A green flashing beacon on a vehicle means the driver or passenger is a doctor on an emergency call. Give way to them if it's safe to do so. Be aware that the vehicle may be travelling quickly.

All warning signs are triangular, but the 'give way' sign is the only triangular sign that points downwards; this is to give it greater prominence as you approach a junction. When you see this sign, you must give way to traffic on the road that you're about to join.

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.

At night or in poor visibility, reflective studs in the road help you to judge your position on the carriageway; the colour of the stud will assist you further. Where slip roads join or leave the motorway, green studs are used.

Most power steering systems only work when the engine is running. If the power steering system fails (or the engine cuts out), much more effort will be needed to steer the vehicle.

Check all tyres (including the spare) at least once a week. Do it when they're cold and remember to refit the valve caps. The vehicle handbook will tell you if you need different pressures for different conditions. Remember: because it's so dangerous, it's an offence to use a vehicle with an improperly inflated tyre.

Even an empty roof rack will create extra wind resistance and this in turn will increase the vehicle's fuel consumption; for this reason, remove a roof rack when it's not needed.

If the amber warning lights come on as you're approaching the crossing, you must stop unless it's unsafe to do so. Red flashing lights together with an audible signal mean you must stop. If the warning lights and alarm start as you're driving over the crossing, continue and clear the crossing; it would be dangerous to stop at that point.

Selecting a low gear when travelling downhill will help you to control your speed. The engine will assist the brakes and help prevent your vehicle from gathering speed.

Cars are designed to have an aerodynamic shape; an empty roof rack causes drag and increased wind resistance. The increased wind resistance will waste fuel; it also increases emissions and causes unnecessary pollution to the atmosphere.

A roof rack increases your car's wind resistance. This will cause an increase in fuel consumption, so you should remove it when it isn't being used.

Letting your vehicle roll or coast in neutral reduces your control over steering and braking. This can be dangerous on downhill slopes, where your vehicle could pick up speed very quickly.

When approaching a zebra crossing, drivers should look out for pedestrians wanting to cross. If anyone is waiting, you should slow down and be ready to stop and let them cross.

Progressive braking is a safe driving technique, which allows other drivers time to react and is more comfortable for your passengers. This will help to prevent skidding, and saves wear on brakes, tyres and suspension.

In general, the vehicle handbook will recommend higher tyre pressures for continuous high-speed driving; for example, on long motorway trips. Increased tyre pressures may also be recommended when the vehicle is carrying a heavy load or when towing a trailer.

Most bus lanes may also be used by cyclists. The bus-lane sign will show its times of operation (where time limits apply) and any other vehicles that may also use the bus lane.

This blue circular sign indicates a route available only to the class of vehicle shown. Plan ahead so that when you see the sign, you have time to take another route; this may be indicated by other traffic signs.

Ring roads are designed to keep traffic away from town centres. Unless you need to visit the town centre, you should use the ring road, as this will help to avoid congestion and reduce your journey time.

Hatch markings are used to separate traffic and to protect traffic turning right. Where the boundary line is broken, you may enter the area only if necessary and provided you can see that it's safe. A continuous white line defining the hatched area means that you mustn't enter, except in an emergency. All other rules of the road apply as normal.

An incorrectly adjusted head restraint will offer reduced protection against whiplash injury. When adjusting the head restraint, set it so that it's at least as high as the eyes or top of the ears.
