Do not hold up a long queue of traffic, especially if you are driving a large or slow-moving vehicle. Check your mirrors frequently, and if necessary, pull in where it is safe and let traffic pass.
Being overtaken. If a driver is trying to overtake you, maintain a steady course and speed, slowing down if necessary to let the vehicle pass. Never obstruct drivers who wish to pass. Speeding up or driving unpredictably while someone is overtaking you is dangerous. Drop back to maintain a two-second gap if someone overtakes and pulls into the gap in front of you.
DO NOT overtake where you might come into conflict with other road users. For example
- approaching or at a road junction on either side of the road
- where the road narrows
- when approaching a school crossing patrol
- on the approach to crossing facilities
- where a vehicle ahead is slowing to stop for a pedestrian that is crossing from a pedestrian island (see Rule 165)
- between the kerb and a bus or tram when it is at a stop
- where traffic is queuing at junctions or road works
- when you would force another road user to swerve or slow down
- at a level crossing
- when a road user is indicating right, even if you believe the signal should have been cancelled. Do not take a risk; wait for the signal to be cancelled
- stay behind if you are following a cyclist approaching a roundabout or junction, and you intend to turn left. Do not cut across cyclists going ahead, including those using cycle lanes and cycle tracks (see Rule H3)
- stay behind if you are following a horse rider or horse drawn vehicle approaching a roundabout or junction, and you intend to turn left. Do not cut across a horse rider or horse drawn vehicle going ahead
- when a tram is standing at a kerbside tram stop and there is no clearly marked passing lane for other traffic.
DO NOT overtake if there is any doubt, or where you cannot see far enough ahead to be sure it is safe. For example, when you are approaching
- a corner or bend
- a hump bridge
- the brow of a hill.
You MUST NOT overtake
- if you would have to cross or straddle double white lines with a solid line nearest to you (but see Rule 129)
- if you would have to enter an area designed to divide traffic, if it is surrounded by a solid white line
- the nearest vehicle to a pedestrian crossing, especially when it has stopped to let pedestrians cross
- if you would have to enter a lane reserved for buses, trams or cycles during its hours of operation
- after a ‘No Overtaking’ sign and until you pass a sign cancelling the restriction.
Large vehicles. Overtaking these is more difficult. You should
- drop back. This will increase your ability to see ahead and should allow the driver of the large vehicle to see you in their mirrors. Getting too close to large vehicles, including agricultural vehicles such as a tractor with a trailer or other fixed equipment, will obscure your view of the road ahead and there may be another slow-moving vehicle in front
- make sure that you have enough room to complete your overtaking manoeuvre before committing yourself. It takes longer to pass a large vehicle. If in doubt do not overtake
- not assume you can follow a vehicle ahead which is overtaking a long vehicle. If a problem develops, they may abort overtaking and pull back in
Before overtaking you should make sure
- the road is sufficiently clear ahead
- road users are not beginning to overtake you
- there is a suitable gap in front of the road user you plan to overtake.
