Blind spots can occur when bodywork - such as a door or window pillar - restricts your view. Different types of vehicle have different blind spots.

Flashing amber lights are found near schools. They warn you that children are likely to be crossing the road on their way to and from school. Drive slowly until you're clear of the area.

Your vehicle will make more noise than a car, so you should try to avoid making unnecessary noise at any time of the day or night. This is especially important when you're in a residential area at a time when people are likely to be sleeping.

When someone ahead of you switches on their hazard warning lights, it means that they've spotted a hazard that you may not be able to see yet. Slow down and be ready to stop if necessary.

The road ahead is at risk from falling rocks and you may also come across fallen rocks in the road

If there's nothing embedded in the wound, you can control the blood loss by applying pressure to the wound and raising the leg if possible.

Keep a check in your mirrors as you're driving to make sure that the sheets are secure. Air can force itself under the sheets and work them loose.

You don't know what the driver of this car will do. Be prepared for any hazard. The driver may not have seen you. Planning ahead will allow you to be in the correct gear and at the correct speed to cope if this hazard develops.

If you check the engine oil level when your vehicle is standing on a slope, the reading on the dipstick won't be accurate. Park it on flat ground, so the dipstick shows the true level.

On a motorway where there's a long uphill gradient, there may be a crawler lane. This helps the traffic to flow by making an extra lane available on the left for slower, heavy vehicles.

A green flashing light 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 or may stop suddenly.

If a build-up of water prevents the tyres from gripping the road, the steering can become unresponsive. If this happens, ease off the accelerator and slow down gradually.

These markings are found on the road outside schools. Don't stop or park on them, even to set down or pick up children. The markings are to make sure that drivers, riders and children have a clear view.

Goods vehicles with a maximum authorised mass of more than 7.5 tonnes (including any trailer) mustn't be parked on a verge without police permission. The only exception is when this is essential for loading and unloading. In these cases, the vehicle mustn't be left unattended.

Lorries and buses are much heavier than cars and will have a greater impact on the road surface.

If you're waiting to emerge from a side road, remember to look for motorcycles. Their small size makes them easy to overlook. Be especially careful if parked vehicles are restricting your view. If you can't see, don't go.

If you're using a vehicle equipped with an analogue tachograph, you'll need at least one chart for every 24 hours. Your employer should supply you with enough tachograph charts for your entire journey.

If your vehicle is to be left unattended on a verge, you must first get permission from the police.

Some foods need to be transported at controlled temperatures. Drivers will need to be trained in the use of refrigeration units and correct hygiene procedures.

You have a legal responsibility to make sure that your vehicle is fully roadworthy. Daily walk-round checks give you the chance to look for any defects with your vehicle.

If you overfill the engine with oil, you could cause the engine to build up too much pressure when it's running. This could cause damage to oil seals and gaskets.

You must obey these signs even if there appear to be no problems ahead.

This is a warning sign to indicate loose chippings ahead. The sign is usually accompanied by an advisory speed limit. Vehicles travelling too fast for the conditions can throw up chippings or stones. Avoid causing damage to paintwork and windscreens by keeping your speed down.

Motor vehicles over 7500 kg maximum authorised mass (MAM) and trailers over 3500 kg MAM should have these markings fitted to the rear of the vehicle/trailer.

If a police officer signals for you to stop, stop as soon as possible in a safe place on the left.

Modern tankers are fitted with baffle plates inside the tank compartment. These help to minimise the movement of liquids and, therefore, reduce the 'wave effect'.

If you stop to give help at an incident and there are casualties, don't move injured people unless there's further danger. Keep them warm, comfortable and calm. Don't give them anything to drink.

Before driving a vehicle fitted with anti-lock brakes, refer to the handbook. This will give you details of the manufacturer's recommended method of use. Remember, anti-lock brakes will enhance your skills, but they can't replace them.
