These are known as advanced stop lines. When the lights are red (or about to become red), you should stop at the first white line. However, if you've crossed that line as the lights change, you must stop at the second line even if it means you're in the area reserved for cyclists.

Having your car registration number etched on all your windows is a cheap and effective way to deter professional car thieves.

Temporary restrictions on motorways are shown on signs that have flashing amber lights. At the end of the restriction, you'll see this sign without any flashing lights.

Try to give way to buses if you can do so safely, especially when the driver signals to pull away from a bus stop. Look out for people getting off the bus or running to catch it, because they may cross the road without looking. Do not accelerate to get past the bus, and do not flash your lights, as this could mislead other road users.

If a tow hitch fails, the trailer must stay connected to the towing vehicle. This is achieved by using a secondary coupling device, such as a safety chain.

The registered keeper of the vehicle is responsible for paying the vehicle tax or making a Statutory Off-Road Notification (SORN) if the vehicle is to be kept untaxed and off the road.

In the event that the trailer becomes detached from the towing vehicle, the breakaway cable activates the trailer brakes before snapping. This allows the towing vehicle to get free of the trailer and out of danger.

Your vehicle must have valid insurance cover before you can tax it. If required, it will also need to have a valid MOT certificate. You can tax your vehicle online, by phone or at certain post offices.

Check the tyre pressures when the tyres are cold. This will give you a more accurate reading. The heat generated on a long journey will raise the pressure inside the tyre.

Practise good observation in all directions before you emerge or make a turn. Proceed only when you're sure it's safe to do so.

You should only flash your headlights to warn others of your presence. Do not use them to greet others, show impatience or give priority to other road users, because they could misunderstand your signal.

Along the hard shoulder there are marker posts at 100-metre intervals. These will direct you to the nearest emergency telephone.

When surface spray reduces visibility, switch on your headlights on dipped beam. This will help other road users to see you.

Using your hazard warning lights, as well as your brake lights, will give the traffic behind an extra warning of the problem ahead. Only use them for long enough for your warning to be seen.

Avoid blocking tram routes. Trams are fixed on their route and cannot manoeuvre around other vehicles or pedestrians. Modern trams travel quickly and are quiet, so you might not hear them approaching.

Allow the cyclist plenty of room in case they wobble or swerve around a pothole or raised drain. Look well ahead before you start to overtake, because you'll need to cross the hazard line. Look for entrances where vehicles could be waiting to pull out.

When performing CPR on an adult, you should use 2 hands and press down 5 to 6 cm. For a child, you may only need to use one hand and should only press down 4 to 5 cm. For an infant, you should use 2 fingers and press down about a third of their chest depth.

You must use dipped headlights when daytime visibility is seriously reduced, generally to 100 metres (328 feet) or less. You may also use front or rear fog lights, but they must be switched off when visibility improves.

Cyclists, and motorcyclists, are very vulnerable in high winds. They can easily be blown well off course and veer into your path. Always allow plenty of room when overtaking them. Passing too close could cause a draught and unbalance the rider.

To avoid being unbalanced, a motorcyclist might swerve to avoid potholes and bumps in the road. Be prepared for this and allow them extra space.

It's illegal to use a hand-held mobile phone while you're driving, except in a genuine emergency. Even using a hands-free kit can distract your attention. Park in a safe and convenient place before receiving or making a call or using text messaging. Then you'll also be free to take notes or refer to papers.

Look out for warning signs as you’re driving. They'll tell you what hazards you may find ahead. For example, pedestrians, wild animals or cattle. To deal safely with any hazards in the road, be prepared to slow down or stop.

You may pass slower vehicles on their left while travelling along a one-way street. Be aware of drivers who may need to change lanes and may not expect faster traffic passing on their left.

Keeping to the left as you approach right-hand bends will give you an earlier view around the bend and allow you to see any hazards sooner. It also reduces the risk of collision with any oncoming vehicle that may have drifted over the centre line while taking the bend.
