Electronic Road Pricing (ERP) 2.0

Motorcycles

• A single-piece design that includes a Processing Unit and a small touchscreen for riders to toggle through different functions.
• To be mounted on left mirror mount (subject to technical assessment by the workshop), similar to IUs today. 

Cars and all other vehicles

Cars and all other vehicles will be fitted with a three-piece design, comprising an Antenna, Processing Unit and an optional Touchscreen Display. 

Antenna

• Communicates with the satellite system and carpark gantries.
• Mounted on the windscreen. 

• Processes all payment-related transactions, and is where the valid CEPAS card should be inserted.
• The exact placement varies by vehicle type and interior. Possible locations include placing it at the front passenger footwell, under glovebox, driver's area or under driver's seat. Technicians will advise on the feasible options and motorists can decide their preferred placement. Click here for more details.   

Touchscreen Display (highly recommended to install, though it is optional)

• Allows motorists to control the volume of OBU alerts.
• Notifies motorists about ERP and payment info, and provides real-time road and traffic updates.
• Allows motorists to temporarily disable card payments, for complimentary parking
• In future, the Touchscreen Display also enables motorists to pay for usage licenses such as for off-peak cars, classic/vintage vehicles, tolls at existing Woodlands and Tuas checkpoints, and roadside parking. 
• Displays information in an easy-to-read graphical or numerical format, with minimal wording, similar to ERP gantries and road signs. 
• Installing the Touchscreen Display is optional. You can indicate your preference when scheduling your OBU installation appointment with your preferred workshop. The workshop will confirm this with you during your installation appointment as well.
• If you choose to install the Touchscreen Display, the workshop will also confirm with you the exact position of the display. In most vehicles, it is mounted on the windscreen, in front of the antenna, for easy viewing by the driver. 

What are the benefits of installing the Touchscreen Display? 

Only selected fleet will be notified by LTA separately to schedule an appointment directly with one our authorised Appointed Partners (AP).  The list of APs and their contact information can be found here.  

It is not mandatory for laid-up vehicles to have an OBU as such vehicles are not allowed on the roads during the lay-up period. More details will be provided in due course. However, if a laid-up vehicle is reinstated during the OBU installation period, they will be scheduled for OBU installation. Once the installation exercise concludes, owners will need to arrange for installation within 5 calendar days of the laid-up status being reinstated. In both cases, the OBU and OBU installation is free if installed within the allocated period.

Will there be any changes to my congestion pricing after I install the OBU? 

The current form of congestion pricing will continue for now, i.e. cordon and point-based pricing. ERP will still be deducted at the physical gantries during the transition period.

When will distance-based road pricing commence? 

There are no immediate plans to impose distance-based road pricing. Any form of distance-based road pricing using ERP 2.0 is still several years away. Our present key focus is to ensure the smooth implementation of the new system, and to allow ERP 2.0 to stabilise.

LTA mentioned the possibility of new charging points. Where will these be?

Similar to the current approach, new charging points may be set up at congested stretches of roads. The aggregated traffic data collected by ERP2.0 will help LTA review the traffic conditions across Singapore. Unlike the current ERP system, we will not need to set up physical gantries under ERP2.0. When the ERP2.0 installation exercise has been completed, new charging point would be indicated by road signages as well as via OBU Touchscreen Display, without any physical gantry. More details will be shared when ready.

Not all motorists have established relationships with workshops, or their regular workshops may not be authorised for OBU installation. Won’t the original booking site make it more convenient for them to get an appointment? Why isn’t LTA maintaining the original booking site for this group?

Many existing vehicle owners have proactively booked OBU installations with workshops directly, likely because of convenience or established relationships with workshops. This approach also allows motorists to conveniently combine OBU installation with other services, such as vehicle servicing, reducing downtime.

As maintaining two booking systems (LTA and workshops) may increase the potential for booking conflicts, we have streamlined the process and redesigned LTA’s original booking site to help motorists locate suitable workshops for their vehicle make. If preferred workshops are unavailable or not authorised for OBU installation, motorists can choose other authorised workshops from go.gov.sg/book-obu to contact the workshop directly or contact LTA's Call Assist Service for help.

Previously, LTA mentioned that there would be a two-month window after being notified by LTA and a partial installation fee, amounting to $35 for motorcycles and $70 for other vehicles would be applied if vehicle owners miss this window. Is this still the case?

During this period, we will waive the partial installation fee. However, we strongly encourage vehicle owners to install the OBU within six months upon being notified by LTA.   

We encourage everyone to make an appointment soon, to ensure that they can get an appointment with their preferred authorised workshop at their preferred time. Motorists can also consider conveniently combining OBU installation with routine vehicle servicing. They need not wait for the notification letter.

Why does my eligibility status reflect "scheduled for installation at a later time" when I keyed in my vehicle plate number?

LTA has scheduled your vehicle for OBU installation at a later stage. But if you prefer to install OBU in your vehicle prior to receiving LTA's notification (e.g. IU is faulty), please contact LTA's Call Assist Service for assistance. 

Why are LTA-authorised workshops only able to install the OBU? How may I apply to be an authorised workshop?

Similar to the in-vehicle unit (IU) today, only LTA authorised persons (e.g. authorised workshop technicians) are able to install the IU / OBU in motor vehicles. Self-installation of the IU / OBU is not permitted, and doing so is an offence under the Road Traffic Act (Electronic Road Pricing System) Rules 2015. Should any motor vehicle dealer / distributor (e.g. parallel importers) require assistance with OBU installation in new local vehicles, please approach an LTA appointed installer for assistance.

For existing vehicle owners, you may visit go.gov.sg/book-obu to find an LTA-authorised workshops that’s suitable for your vehicle make, to schedule an appointment for OBU installation.

If you wish to apply to be an authorised workshop, please write in to LTA at LTA_OBU_LNO@lta.gov.sg.

I have received a notification to install OBU but I am intending to sell my vehicle. Do I need to install the OBU before doing so? 

The ownership of a vehicle can be transferred with or without the OBU installed. You can go ahead to transfer the vehicle even if the OBU was not installed yet. The notification will be void at LTA’s end and there will be no action required on your part. A new notification will be sent to the new vehicle owner instead.

Why can't I use the one-piece OBU (for motorcycles) for my car? I drive an open-top vehicle, why can't I use the one-piece OBU?

The OBU offers more functionalities and supports wireless connections with more stringent security measures. It is bigger due to the larger computation power required.

With a bigger size, it is therefore designed as a three-piece unit, suitable for indoor use. The processing unit of the three-piece OBU is mounted away from the dashboard and only the antenna, which communicates with the gantries and satellites, is mounted on the dashboard.

On the other hand, the single-unit OBU is designed for outdoor conditions. The single-unit OBU with the integrated antenna cannot be mounted on the dashboard inside a vehicle as its heat dissipation is poorer in an enclosed environment, which will affect its reliability.

Will the OBU drain my vehicle's battery?

The OBU needs a constant 12V power supply to operate properly. However, when the ignition of the vehicle is turned off, the OBU will switch to sleep mode and draw even lower power than the IU today. Motorists need not worry that there will be a power failure if they do not drive for a few days.

If your vehicle has faulty batteries / electrical system and cannot provide the constant 12V power supply to OBU, the workshop will advise you to replace the vehicle batteries / electrical system in order not to impact the proper functioning and lifespan of the OBU, which would lead to additional costs and inconvenience for motorists downstream.

Why is installing the OBU Touchscreen Display recommended? 

Motorists are encouraged to install the OBU Touchscreen Display to access the full set of features, such as adjusting the volume of OBU notifications and paying for roadside parking.

However, if you still prefer not to install the OBU Touchscreen Display, you can download a compatible mobile application on your smartphone and connect it to the OBU via Bluetooth.

What will happen to my Touchscreen Display if I choose not to install it? 

If you choose not to install your Touchscreen Display, it will still be given to you. Please ensure that you keep it safely, especially if you wish to install it in the future. 

What should I do if I change my mind regarding the installation of OBU Touchscreen Display after installation? Do I need to pay for this service?

Please visit the workshop that carried out your OBU installation if you wish to install or remove your OBU Touchscreen Display after the initial installation. 

Please note that you will be required to pay for this service as it is beyond the scope of the initial OBU installation which is free to motorists. The fee for this service is determined by individual workshops and may not be uniform across the industry. Therefore, you are advised to check with a workshop before making a decision.  

Where can I purchase a OBU Touchscreen Display if I have misplaced mine?

You will be able to purchase a new OBU Touchscreen Display at the workshop that carried out your OBU installation, or at authorised OBU inspection centres.

However, if you obtain an OBU Touchscreen Display through other unauthorised means, please note that the Touchscreen Display will have to be properly decommissioned from its original vehicle and OBU at the workshop or authorised service centre before it can be commissioned onto your vehicle and OBU. The original vehicle will have to be present at the workshop or authorised inspection centre for the decommissioning process.

The fees for decommissioning and commissioning the Touchscreen Display would be determined by the workshop.

The list of authorised OBU inspection centres can be found here. 

What language will the OBU interface support?

The Touchscreen Display supports English only. However, it has been designed to display information in an easy-to-read graphical or numerical format, with minimal wordings, similar to ERP gantries and road signs today. This enables the information to be conveyed and understood easily.

What is the price of an OBU? 

Until the transition to ERP 2.0 is complete for all vehicles, the price of the OBU for all new vehicles will continue to be charged at the same subsidised rate as IUs ($158.70, inclusive of GST). This excludes the cost of installation that specific authorised dealers/distributors may charge, as per current practice. LTA will announce the final OBU price that would apply after the transition to ERP 2.0 at a later stage.

Will the Processing Unit for three-piece OBU scald or burn me?

The Processing Unit may feel warm, but the protective cover ensures that it is never too hot to touch. 

Is the Processing Unit for the three-piece OBU waterproof? 

The Processing Unit has been tested to be resistant to light splashing. 

My existing IU is faulty. May I request for an early OBU installation, prior to receiving LTA's notification? 

Visit go.gov.sg/book-obu to find a list of LTA-authorised workshops that are suitable for installing the OBU for your vehicle's make, and contact your preferred workshop directly to schedule an appointment.  

My OBU is faulty/not functioning properly/displaying an error message, what should I do?

You will receive a letter from LTA requesting you to visit either the workshop that carried out your OBU installation or the OBU Care Centre. 

If you have not received any letter or inspection notice from LTA, but suspect that there is an issue with your OBU, please visit the workshop that carried out your OBU installation. 

Who is authorised to fix and repair the OBU?

If you suspect that there is an issue with your OBU, please visit the workshop that carried out your OBU installation. The workshop will assess if you need to visit the OBU Care Centre.

Does the OBU come with a warranty? What does it cover?

Each OBU comes with a 5-year warranty, which commences from the date of first installation. The OBU warranty covers all manufacturer’s defects and is subject to limitations of coverage on product failures due to, but not limited to, user negligence, improper installation, accident, mishandling, misuse, tampering, vandalism and unusual operating environments.

If the OBU is under warranty, any part replaced free-of-charge follows the original OBU warranty period. If a replacement part is purchased for an OBU that is not under warranty, the individual part will have its own warranty coverage period. This applies for the single-piece OBU as well.

I need to send my vehicle for repair / maintenance works, but my regular workshop is not an LTA-authorised workshop. Will this void my OBU warranty?

LTA acknowledges that there are workshops who may not be authorised OBU installers but may find themselves inadvertently having to touch the OBU or its wiring for non-OBU related services as part of vehicle-related works (e.g. servicing, maintenance, replacement of vehicle’s air conditioning / solar film / windscreen). We request technicians to carry out such non-OBU related services with caution (e.g. not change the wiring of the OBU). Such non-OBU related services will not automatically void the validity of the OBU warranty, as long as there is no tampering of the OBU.

What if my vehicle gets damaged during the OBU installation? Will my vehicle warranty be voided? 

Technicians from the authorised workshops will be trained with the necessary skill sets to install an OBU. The workshop will also ensure quality standards are met during installation. If a vehicle is damaged during the installation process, the workshop will be expected to rectify the issue. As long as the OBU installation process follows the instructional manual, the vehicle warranty will not be voided. 

Will the OBU warranty be retained through transfer of vehicle ownership (e.g. for those buying second-hand cars)?

Yes. The OBU warranty is tied to the OBU. Therefore, the ongoing OBU warranty will remain valid with any transfer of vehicle ownership. 

If you wish to retain your OBU when you sell your current vehicle and buy a new one, please visit the authorised OBU inspection centres to transfer the OBU within 30 days*. If not, your OBU warranty will become void. The transfer period here refers to the period between the date the OBU is removed from a vehicle and the date it is re-installed onto another vehicle.

*The 30 days limitation is only applicable to the processing unit of the OBU. 

Where can I find the expiry date of my OBU warranty?

You can find your OBU warranty’s expiry date on One Motoring Digital Services.

Why can't alerts and traffic information be displayed on my car infotainment system? 

The display of information via the car infotainment system can only be enabled if it is supported by the vehicle’s manufacturer, or if the mobile application was developed to be compatible with Apple CarPlay and/or Android Auto. Third-party app developers may provide connectivity to the in-vehicle infotainment systems that are compatible with Apple CarPlay or Android Auto. Motorists are advised to look up the respective apps for more information.

I’ve chosen to use a mobile application. What if my phone freezes/runs out of battery or the app malfunctions while driving? 

If the mobile application is unavailable, you will not have access to ERP alerts and other functionalities. However, this will not affect the ERP charging mechanism as the antenna would still be able to communicate with physical gantries or GNSS satellites (when the system completes transition to ERP 2.0), and the processing unit would still be able to process the ERP charges. 

Is my mobile phone compatible with the application?

The latest version and 2 previous major versions of Android and iOS are supported.

How many mobile applications can my OBU be connected to? 

The OBU can only connect to 1 mobile application (be it mobile display app or any other value-added service app) via Bluetooth at any one time. However, it is easy to switch between mobile apps once the phone is paired. Simply close the first app and open another.

When will I be able to pay for roadside parking through my OBU? 

Roadside electronic parking will be implemented towards the end of the OBU installation exercise when most vehicles have transitioned to the new system. In the meantime, motorists can continue to use Parking.sg to pay for parking digitally.

Why is REP only available with the Touchscreen Display? What options do I have if I don't want to install the Touchscreen Display? 

The roadside electronic parking feature offers a way for motorists to conveniently pay for their parking. They can start a parking session via the OBU touchscreen display, which ends automatically when they drive off. This feature is only available for those with the OBU touchscreen display as motorists need to tap on the display to confirm that the correct parking place has been detected before the session commences. Motorists who have chosen not to install their OBU touchscreen display can continue to use the Parking.sg app to pay for their parking.

Are motorcycles, which are only fitted with a single-piece OBU, able to access the REP?  

Yes. Motorcycles fitted with the single-piece OBU can access REP functions.  

Can I use parking.sg and the REP at the same time?

There is no need for motorists to use both systems to start a parking session. We encourage motorists to go through the OBU as the parking process for REP is simpler – motorists will only need to confirm their parking location before starting the parking session, and it will end automatically when motorists drive off. With the REP, there will be no need for motorists to estimate their parking duration, extend or end their session, unlike Parking.sg. 

Will I still be able to access all carparks with the OBU? 

The OBU is compatible with Electronic Parking System (EPS) carparks that are supported by valid CEPAS cards (NETS Flashpay or NETS/EZ-link Motoring cards, or non-SimplyGo EZ-link cards). Season parking in EPS carparks will also continue to be supported. 

Reported issues have generally been traced to the carpark systems themselves, not the OBU. Motorists experiencing difficulties may contact LTA's Call Assist Service and provide us specific carpark details for our investigation. 

Do laid-up vehicles need to install an OBU?

It is not mandatory for laid-up vehicles to have an OBU as they are not allowed to be used on roads during the lay-up period. However, after the end of the on-board unit (OBU) installation period in 2026, if the vehicle is no longer laid-up and is intended to be used on roads, it will then be mandatory for the vehicle to have an OBU installed before using our roads.

How do I go about installing the OBU once my vehicle is no longer laid-up (during and after the installation exercise)? Will installation be free?

If a laid-up vehicle without an OBU is relicensed during the OBU installation exercise, vehicle owners may contact an authorised workshop to schedule an appointment with them directly to install the OBU in your vehicle. You can find a suitable LTA-authorised workshop for your vehicle's make, by visiting go.gov.sg/book-obu. 

If a laid-up vehicle is relicensed after the OBU installation exercise, vehicle owners will need to arrange for OBU installation within 5 calendar days of the vehicle being relicensed, at a suitable LTA-authorised workshop for your vehicle.

My OBU is not working after my laid-up vehicle is re-licensed. What should I do?

You will receive a letter from LTA requesting you to visit either the workshop that carried out your OBU installation or the OBU Care Centre.

If you have not received any letter or inspection notice from LTA, but suspect that there is an issue with your OBU, please visit the workshop that carried out your OBU installation. 

Will data from the OBU be used to identify or track individuals? Who will LTA share the data with and how does LTA safeguard the data?

There are strict safeguards in place to govern the collection, use and storage of data. LTA will only use vehicle specific data for payment charges and enforcement, such as against non-payment of ERP charges.

LTA adheres to Government-wide standards for data security, including strict guidelines on data sharing with other Government agencies. Sharing of data to support policy and planning purposes will be done on an anonymised or aggregated basis. LTA will ensure that necessary safeguards are in place to prevent unauthorised access to personal data. There are criminal penalties for the unauthorised disclosure and improper use of information.
