The 'stop' sign is the only road sign that's octagonal. This is so that it can be recognised and obeyed even if it's obscured; for example, by snow.

Be aware that other traffic might still be clearing the junction. When the green light shows, make sure the way is clear before continuing.

On a single carriageway road, the national speed limit will apply, unless signs indicate otherwise. For a car, the limit is 60 mph unless the car is towing a trailer - in which case the limit is reduced to 50 mph.

The slip road should be used to allow you to accelerate until your speed matches that of the traffic already on the motorway. By doing this, you can join the motorway without affecting the progress of the traffic. At busy times, you may have to slow down to merge into slow-moving traffic. Always give way to traffic already on the motorway.

If you're following a large vehicle but are so close to it that you can't see its exterior mirrors, the driver can't see you. Keeping well back will also allow you to see the road ahead by looking past either side of the large vehicle.

Be aware that elderly people might take a long time to cross the road. They might also be hard of hearing and not hear you approaching. Don't hurry elderly people across the road by getting too close to them or revving your engine.

If you're driving along the motorway in the left-hand lane and you see traffic joining from a slip road ahead, you should move to another lane if it's safe to do so. This can greatly assist the flow of traffic joining the motorway, especially at peak times.

Try to plan your journey so that you can take rest stops. It's recommended that you take a break of at least 15 minutes after every two hours of driving. This should help to maintain your concentration.

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.

Usually, a road is constructed with a camber: the road surface slopes to assist with drainage. Some bends have an 'adverse camber'. This is where the road slopes towards the outside of the bend. When going around a bend that has adverse camber, you need to take extra care. The forces acting on your vehicle could cause it to leave the road more easily than normal.

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.

Don't travel unless you really have to. Making unnecessary journeys will increase the risk of being involved in an incident. If you do decide to use your car, it's important that you can see and be seen. Make sure any snow or ice is cleared from lights, mirrors, number plates and windows.

Don't ignore feelings of drowsiness while driving. You'll need to find somewhere safe to stop and rest until you feel alert enough to continue your journey. On a motorway, you can either stop at a service area or leave the motorway and then find a safe place to stop. Until you reach a safe place to stop, make sure the vehicle is well ventilated. Don't stop on the hard shoulder to rest.

Don't turn your vehicle around on a busy main road. It's safer to find a quiet side road where you can turn around and then rejoin the main road.

On a windy day, the blustery conditions will affect motorcyclists and they may be blown off course. If you wish to overtake a motorcyclist in these conditions, make allowances for them and give them extra room.

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.

Diagonal stripes or chevrons are painted on the road to help separate traffic lanes or vehicles turning right. When bordered by a solid white line, you shouldn't enter the area except in an emergency. If the line is broken, you shouldn't enter the area unless it's necessary and you can see that it's safe.

If a horse is frightened, it may bolt or shy unpredictably, and the rider may lose control. To reduce the risk of frightening the horse, you should not make any unnecessary noise. Pass it slowly and give it plenty of room.

Give way to traffic already on the motorway. If you've matched the speed of traffic in the left-hand lane, you should be able to join where there's a suitable gap in the traffic. Try to avoid stopping at the end of the slip road - but you might have to do so if the motorway is very busy and there isn't a safe gap in the traffi
