When is a vehicle escort required?

The requirement for a heavy vehicle escort is based on the dimensions and/or mass of the heavy vehicle and load combination. This also includes the topography of the road network and traffic volumes.  Refer to the carrying loads bulletin for information on how to safely secure your load.

Heavy vehicle escorts help make sure that OSOM vehicles are able to travel across bridges on the road network at a speed and manned in a way which is not likely to cause unnecessary damage to road or bridge infrastructure. Often this task can only be done safely when all traffic is stopped from entering onto the bridge until the OSOM load has passed.
