Oversize vehicle sign

Sometimes an oversize vehicle may be accompanied by Police or a pilot vehicle (vehicle with flashing lights) to warn traffic that the load following is very wide or long.

You must follow any directions given by Police. You should also follow any reasonable directions given by the occupants of the pilot vehicle provided you do not break the law.

When approaching an on-coming oversize vehicle you should:

  • Be careful and reduce speed.
  • Keep to the left of the centre line.
  •  Be prepared to move to the left side of the road if necessary.

You should use extreme care when overtaking an oversize vehicle.

Large, heavy turning vehicles

Be careful of large, heavy vehicles displaying a DO NOT OVERTAKE TURNING VEHICLE sign as they may use more than one lane when turning left or right.

When it's not safe to overtake

Light rail vehicles

When a light rail vehicle is coming towards you, keep to the left unless there is a barrier between you and the light rail vehicle.

Only overtake on the left to pass a light rail vehicle travelling in the centre or on the right hand side of the road.

You should overtake on the right when the light rail vehicle is on the left hand side of the road.

You must not overtake a light rail vehicle on the left if it is turning or signalling to turn left. If it is turning or signalling to turn right, you must not overtake it on the right.

Bridges

Approach bridges with care as they are often narrow. If you think two vehicles cannot fit on a narrow bridge, give way to the other driver.

When you come to a bridge which is wide enough for only two vehicles, slow down and drive carefully. Sometimes you are not allowed to overtake a vehicle going in the same direction or to pass a vehicle coming towards you.

The following signs tell you what to do:

Give way sign

You must give way to any vehicle travelling in the opposite direction on the bridge.

No overtaking sign

You must give way to any vehicle travelling in the opposite direction on the bridge.

You must not overtake any vehicle travelling in the same direction.
