NTC looks to change warning triangle standards

NTC calls on trucking industry to offer views on proposed changes to portable warning triangles in NSW

The National Transport Commission (NTC) has called on the trucking industry to put forward its views on proposed changes to portable warning triangles in NSW.

The changes were proposed by the Roads and Traffic Authority (RTA) following a coroner’s report into a B-double accident in 2006.

If the proposal is accepted, it would be mandatory for the triangles to be placed a further 150 metres from a stricken vehicle.

According to the RTA, the current Australian Road Rule 227 (4) which requires a driver to place the warning sign between 50 and 150 metres in front and behind a truck does not provide an adequate safety margin for a large vehicle such as B-double travelling at its maximum allowable speed.

"The National Transport Commission’s Network Classification Guidelines recommend a stopping sight distance of 135 metres for a B-double stopping from a speed of 70km/h and 238 metres for a B-double combination stopping from 100km/h,"the RTA says.

The NTC is also calling on the industry to provide its views on whether there should be a national standard for the design of portable triangles.
