Driving an Over-Height Vehicle? Warning System Will Alert You to Risk Ahead

News Releases 26 Sep 2014 warning system overhead road structures

Six-month trial for Vehicle Height Limit Warning System from 30 September

          From 30 September, the Land Transport Authority (LTA) will conduct a trial along Upper Bukit Timah Road to test if a warning system can alert drivers of over-height vehicles so that they can avoid hitting overhead road structures with a 4.5m clearance, such as pedestrian overhead bridges and gantry signs.

2.        When the system senses an approaching over-height vehicle, it will display a visual warning to alert the driver that his vehicle may hit the structure.

3.        This will be a six-month trial, and LTA will evaluate the effectiveness of such a system to see if it can be extended to more locations.

4.        While incidents involving over-height vehicles hitting overhead structures are relatively low, a damaged overhead road structure can pose significant danger to the vehicle drivers as well other road users. Since 2010, there were 24 cases of overhead road structures hit by vehicles that go over the height limit. Many of these incidents can be prevented as they were caused by drivers who forget to fully retract their machinery, for example, crane booms on their heavy vehicles, before driving off.

Enforcement and public education effort

5.        This trial will complement LTA’s existing enforcement and public education effort. Besides enforcement, LTA carries out public education through the distribution of brochure and stickers to remind drivers of heavy vehicles to fully retract their machinery when on the road.

6.        Those found guilty of hitting road structures will be fined a maximum of $5,000 or can be jailed for up to two years. Apart from the penalty, the owner or driver of the vehicle will also have to pay for the repairs of the damaged road structure.

7.         It is also an offence to drive a vehicle exceeding 4.5m in height without a police or auxiliary police escort. If found guilty, the driver may be jailed up to five years, fined $5,000 and disqualified from driving for two years.

8.         Please refer to the Annex for a location map of the trial system and system illustration.
