Sharing the road with overdimension vehicles

You will sometimes see overdimension vehicles, such as vehicles carrying buildings, on the road. Because of their size, and because they travel slower than other vehicles, you need to be especially careful when driving near them.

• You will usually have advance warning of extremely large vehicles, as they have pilot vehicles travelling with them to warn you (see Vehicle-mounted signs for more information). Oversize vehicles will be equipped with hazard panels, beacons and flags.
• Slow down and be prepared to do what the pilot vehicle instructs you to do.
• Be patient – a few minutes of travelling at a slow speed is better than risking an accident.
• Be extremely careful when passing and only pass when it is safe and legal to do so (see Passing for more information). Remember that wide or long loads can make passing more difficult.
