What does a lorry restriction sign mean?
The Land Transport Authority (LTA) restricts goods vehicles from certain roads. On LTA's commercial vehicles page, the rule applies to roads that carry both a "Lorry Restriction" traffic sign and an "Except Authorised Vehicles" supplementary plate. A tipper truck is a goods vehicle, so it is covered.
On such a road, an application must generally be made to LTA for the goods vehicle to be authorised to enter. Make sure the site, not just the driver, knows about any restricted road before the truck is dispatched.
Is every goods vehicle affected?
Not always. LTA says that where the supplementary plate shows a weight limit, goods vehicles below that limit need not submit an application. A different sign, "No entry for goods vehicles", is explained on LTA's driving rules page: vehicles whose laden or unladen weight exceeds the stated weight are prohibited, and a vehicle over the limit must have a public escort. That page also shows a separate "No entry for vehicles with 3 or more axles" sign.
| Sign | What LTA says |
|---|---|
| Lorry Restriction + Except Authorised Vehicles | Goods vehicles generally need LTA authorisation to enter |
| Same sign with a weight limit plate | Vehicles below the limit need not apply |
| No entry for goods vehicles | Vehicles above the stated weight are prohibited; over-limit vehicles need a public escort |
| No entry for vehicles with 3 or more axles | Vehicles with three or more axles may not enter |
Read the actual plate at each road. Weight limits and conditions differ between locations.
How do you apply for authorisation?
LTA's page sets out the process for the vehicle owner or driver:
- Check the route first. Authorisation is for vehicles that cannot reach their destination through alternative access points or routes.
- Confirm the purpose. The vehicle must be used for repair or maintenance work, courier delivery, or construction services.
- Submit details through Form.SG. LTA links the form from the commercial vehicles page.
- Mind the 7-day limit. Authorisation covers a period of up to 7 days. To enter the road after that, a new application has to be made.
LTA lists refuse collection vehicles as already authorised. Tipper trucks hauling earth, sand or debris are not named in that exemption, so plan to apply.
What should a site manager plan before trucks arrive?
- Map the access road and look for the signs. Do this before the first tipper is booked, not on the morning of the haul.
- Ask whether an alternative route exists. If one does, LTA's criteria (authorisation is for vehicles with no alternative route) mean an application may not be approved.
- Diarise renewals. A project that needs more than 7 days of access has to reapply, so make it part of the weekly site plan.
- Share the details with the driver. Give the dispatcher the authorised road, dates and gate to use.
- Confirm with LTA. Rules and forms can change. Treat this article as a pointer and confirm current requirements on LTA's OneMotoring site.
How Vanguard Transport fits in
Vanguard Transport supplies tipper trucks with Vanguard drivers, allocated to your project for the length of a long-term contract, for earth, sand, aggregate and demolition debris. Our tipper trucks go up to 51 tonnes gross vehicle weight, so weight limits on access roads matter for planning. Our drivers are briefed on site-specific hazards before mobilising. See tipper truck transport, our fleet, or talk to us about your site access.
Frequently asked questions
Do tipper trucks need LTA authorisation to use lorry-restricted roads?
Generally yes, where the road has both a "Lorry Restriction" sign and an "Except Authorised Vehicles" plate. If the plate shows a weight limit, vehicles below it need not apply. Confirm with LTA.
How long does LTA authorisation last?
LTA states that an application can be made for a period of up to 7 days. A new application is needed to enter the road after that period.
Can I apply if another route is available?
LTA's process is for vehicles that cannot reach the destination through alternative access points or routes, and that are used for construction services, repair and maintenance, or courier delivery.
Where do I apply?
Through Form.SG, linked from LTA's commercial vehicles page on OneMotoring.
