The lights that control the crossing show to both directions of traffic. If a pedestrian from either side is still crossing when the amber light is flashing, you must wait.

Elderly people may misjudge how far away you are and how fast you're travelling. This may cause them to step into the road when you would expect a pedestrian to wait. They may also walk slowly and so could take a long time to cross the road.

The speed limit on a dual carriageway or motorway is 70 mph for cars and motorcycles, unless there are signs to indicate otherwise. If your car or motorcycle is towing a trailer, then a lower national speed limit applies. The speed limits for different types of vehicle are listed in The Highway Code.

There's usually a 30 mph speed limit where street lights are less than 185 metres (600 feet) apart.

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 may only stop on the carriageway of a motorway
- when told to do so by the police
- when a red cross with flashing red lights shows above every lane - in a traffic jam
- in an emergency or breakdown.

If the lights at a level crossing continue to flash after a train has passed, wait, as there might be another train coming. Time seems to pass slowly when you're held up in a queue. Be patient; there's a good safety reason why the barriers have remained down and the lights continue to flash.

If your tyre pressures are lower than those recommended by the manufacturer, there will be increased rolling resistance. To overcome this, the engine will have to work harder, resulting in increased fuel consumption. Check your tyre pressures at least once a week.

Where there are double white lines in the middle of the road and the line nearest to you is broken, you may cross the lines to overtake, provided it's safe and you can complete the manoeuvre before reaching a solid white line on your side.

Routine checks, particularly before a long journey, can help to save trouble and expense. Check the operation of all lights, including the brake lights, each time you use the vehicle.

A mirror with convex glass gives a wide field of vision. This makes everything appear smaller and further away than it would look in a flat mirror.

Time your driving and adjust your speed so that you don't have to use your brakes while you're cornering. Braking on an icy or snow-covered bend is potentially dangerous. The cornering force will continue to pull you outwards and the tyres will have very little grip. This could cause your vehicle to skid.

It's recommended that you check all the lights on your vehicle on a daily basis and replace any faulty bulbs. Carrying spare bulbs and fuses in your vehicle will ensure you can replace a bulb as soon as you find it has failed.

If any warning light shows while you're driving, it indicates a fault that needs prompt attention. If the warning light for the anti-lock brake system shows, have the braking system checked before driving further.

Before starting any journey, make sure your windows and mirrors are clean and your lights are working. You need to be able to see clearly and be seen by other road users. This is especially important when visibility is reduced, as in fog or heavy rain.

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.

Make sure you know what the different warning lights mean. An illuminated warning light could mean that your car is unsafe to drive. Don't take risks. If you're not sure about the problem, get a qualified mechanic to check it.

You must know the speed limits that apply to the vehicle you're driving. On a motorway, the speed limit for a car is 70 mph - but if it's towing a trailer, that limit is reduced to 60 mph.

Strict controls on exhaust emissions require a catalytic converter to be fitted to the exhaust system of all new vehicles. Catalytic converters remove most of the carbon monoxide, oxides of nitrogen and unburned hydrocarbons from the exhaust gases.

At a pelican crossing, there's a phase where the amber light flashes. This will show after the red light and gives pedestrians time to finish crossing safely. For drivers, the flashing amber light means they may drive on if the crossing is completely clear, but they must wait if pedestrians are still on the crossing.
