You must obey signals given by police officers, traffic officers, traffic wardens and signs used by school crossing patrols. When a police officer signals to you to stop, you should stop safely on the left and switch off your engine.

You must stop if there's a red cross with red lights flashing above every lane on the motorway. However, if the signs over any of the other lanes don't show this signal, you may move into one of those lanes and continue, if it's safe to do so.

These lights warn that children may be crossing the road to a nearby school. Slow down so that you're ready to stop if necessary.

At a roundabout, a horse rider wanting to turn right may feel safer keeping to the left all the way around the roundabout. Stay well back. Driving close behind or alongside could frighten the horse.

Always carry an advance warning triangle, or other permitted warning device, in your vehicle. Use it to warn other road users if your vehicle has broken down or there's been an incident. You're advised to place it about 45 metres (147 feet) behind the vehicle, on the same side of the road. You may need to place it further back if the vehicle is hidden by, for example, a bend, hill or dip in the road. Never attempt to place any warning device on a motorway.

If your view of the road ahead is restricted because you're being dazzled by approaching headlights, slow down and, if you need to, stop.

Some zebra crossings are divided by a central island. Each half is a separate crossing.

Always stay in the middle of your lane until you need to change course. This is even more important when in narrow lanes; for example, at roadworks. Be aware of large vehicles that may have to straddle more than one lane.

It's dangerous for vehicles to travel too close together. Visibility is reduced and there's a higher risk of collision if a vehicle brakes suddenly to avoid a hazard. By increasing the separation distance between you and the vehicle in front, you have a greater safety margin. If necessary, this will allow you to reduce speed gradually and so avoid the vehicle behind being unable to stop within the space it has allowed.

When you're overtaking on a motorway, you'll sometimes find faster vehicles approaching from behind. When it's safe to do so, you should move over and let them pass. Don't try to enforce the legal speed limit.

Large, long vehicles need extra room when making turns at junctions. They may move out to the right in order to make a left turn. Keep well back and don't attempt to pass on the left.

When parking on a hill, there's a risk of the car rolling if the parking brake fails. To reduce this risk, turn the front wheels towards the kerb. This will allow the kerb to act as a chock, preventing any forward movement of the vehicle.

If you're driving a vehicle that breaks down on an automatic level crossing, don't delay in getting everyone out of the vehicle and well clear of the crossing. You should then use the emergency telephone to tell the signal operator of the obstruction.

Sometimes, large vehicles may need more space than other road users. If a vehicle needs more time and space to turn, be prepared to stop and wait.

If you meet another vehicle on a narrow road, pull into the nearest passing place on the left. If the nearest passing place is on the right, wait opposite it.

On main beam, your headlights are liable to dazzle a driver who's overtaken you. For this reason, you should dip your headlights as soon as the overtaking vehicle passes you. When following another vehicle at night, make sure that your headlights are on dipped beam and the light beam falls short of the vehicle in front.

If your vehicle breaks down on a level crossing, your priority is to get everyone out of the vehicle and clear of the crossing. If there's a railway telephone, use it to tell the signal operator what's happened. If you have time before a train arrives, move the vehicle clear of the crossing, but don't attempt this if the crossing alarm sounds.

When your vehicle is too big to fit into the central reservation, you should treat a dual carriageway as one road and wait until the road is clear in both directions before emerging to turn right. If you try to treat it as two separate roads and wait in the middle, your vehicle will overhang the central reservation and could cause a collision.

Following too closely behind another vehicle at night may dazzle the driver. If you drop back, your headlight beam will fall short of the vehicle and so avoid dazzle.

Large vehicles can throw up a lot of spray when the roads are wet. This will make it difficult for you to see ahead. Dropping back will move you out of the spray and let you see more of the road ahead.
