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 handlebars, 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.
• You will have a choice on the exact placement of the Processing Unit within your vehicle. The workshop will confirm with you on your choice during the installation appointment

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

• Notifies motorists about ERP and payment info, and provides other info such as locations of nearby Silver Zones, bus lanes etc.
• Installing the Touchscreen Display is optional. You can indicate your preference when booking your OBU installation appointment. 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. 
• Displays information in an easy-to-read graphical or numerical format, with minimal wording, similar to ERP gantries and road signs.
• Allows driver to control the volume of OBU alerts.

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.

Where can I register my interest and book my OBU installation?

LTA will notify you when your vehicle is due for OBU installation. Upon receiving the notification, you can book an appointment via LTA’s booking website using your Singpass. The list of available workshops and operating hours can be found here.

If you wish to install the OBU ahead of your official notification, please contact LTA’s Call Assist Service at 6377-2255.

How can I book an appointment if I do not have Singpass?

You can contact LTA’s Call Assist Service at 6377-2255 to make your appointment.

Who can bring my vehicle down for OBU installation? 

After your appointment is made, anyone can bring your vehicle down for OBU installation on your behalf. No documents are required. 

My two-month eligibility window has passed. What can I do?

You can still proceed to make an appointment via the appointment booking website. However, as you have missed your two-month eligibility window, you will have to pay part of the installation fees, amounting to $35 for motorcycles and $70 for other vehicles. Installation fees will be collected during your appointment.

Why is my Vehicle Registration Number (VRN) reflected as 'not eligible' for free OBU installation on the appointment booking website?

Your vehicle is not scheduled for OBU installation yet. LTA is commencing the OBU installation exercise in phases from 1 Nov 2023, starting with fleet vehicles (e.g. public buses, goods vehicles and motorcycle fleets) and motorcycles.  LTA will notify you when your vehicle is due for OBU installation. 

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.

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 an authorised OBU inspection centres.

However, if you obtain an OBU Touchscreen Display via 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.

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. 

My existing IU is faulty. May I request for an early OBU installation? 

You may visit any authorised OBU inspection centre to replace your faulty IU with the OBU, at no cost. 

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

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

You will be issued a vehicle inspection notice (VIN) if your OBU malfunctions. You must visit an authorised OBU inspection centre after you have received the VIN.

You may also visit the workshop that carried out your OBU installation, or an authorised OBU inspection centre prior to receiving a VIN if you notice your OBU is malfunctioning*. 

*Non-payment of ERP charges due to OBU malfunctions will be reviewed on a case-by-case basis. 

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

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.

Authorised OBU inspection centres and OBU installation workshops, and Care Centres are all trained to inspect and replace the OBU. If you receive a VIN, you will need to go to an authorised inspection centre to have your OBU inspected.

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

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.

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.

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

The on-board unit 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. 

Do laid-up vehicles need to install an on-board unit?

It is not mandatory for laid-up vehicles to have an on-board unit (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, 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, it will be automatically scheduled for OBU installation. Vehicle owners will receive a letter, email and/or SMS from LTA when it is their turn, and they will need to book an appointment and install the OBU within the two-month time period indicated in the notification.

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 any authorised OBU installer.

In both cases, the OBU and its installation fee will be free if it is installed within the respective allocated periods.

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

If the OBU is faulty/not functioning properly but is still able to switch on, the vehicle owner will receive a vehicle inspection notice (VIN). Vehicle owner must visit an authorised OBU inspection centre after he has received the VIN. 

If the OBU is not functioning/unable to be switched on, the vehicle owner must visit an authorised workshop or OBU inspection centre. If necessary, a new OBU may be installed at the vehicle owner’s cost.

List of authorised workshops can be found here.

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.
