PCV - Free Test #4

The reverse warning bleeper is fitted to your vehicle to warn others near the vehicle that it's reversing. However, it's no substitute for good all-round observation. Get someone to guide you if you can't see clearly where you're reversing.

When visibility is poor or the road is wet, leave a greater separation distance - at least a four-second time gap from the vehicle in front. You should also reduce speed and use dipped headlights.

Drivers are required to take 35 hours of training every five years to maintain their Driver CPC. This can be split into shorter sessions of at least seven hours each. These can be spread over the five years, so effectively one day's training is taken each year. The penalties for non-compliance are the same as those for driving without a licence.

Cyclists and motorcyclists may become unbalanced by your vehicle passing too close. Plan ahead and give them plenty of room. Remember that your large vehicle can cause a vacuum, which will suck the rider towards it. The noise and close proximity of your vehicle can also startle them, and could cause them to swerve suddenly.

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

An engine fitted with a turbocharger should be allowed to idle for about a minute before it's switched off. This prevents the turbocharger bearings from being starved of oil.

Moisture in the air condenses as the air pressure increases. This moisture can be transmitted around the braking system and is especially dangerous in cold weather. It can lead to ice forming and blocking the valves and pipes.

Before uncoupling a trailer, always make sure that you've parked on firm, level ground and applied the trailer parking brake.

If you're involved in an incident that causes damage or injury to a person or property, you must stop. You must also give your details to anyone who has reasonable grounds to ask for them. If you don't do this, you must inform the police as soon as possible and in any case within 24 hours.

If your vehicle breaks down, try to stop on the left, facing in the same direction as the flow of traffic. This will help other drivers to see you, as your red reflectors will show to the rear. Don't stop on the pavement, as the weight of the vehicle may damage paving stones and underground services.

On the approach to many tunnels, a board will indicate a local channel or radio frequency that you should tune into. This should give a warning of any incident or congestion in the tunnel ahead. Severe loss of life has occurred in tunnel fires. Getting advance warning of any problems ahead will help you to take appropriate action in good time.

By using a bypass, rather than joining the stop/start traffic in a town centre, you're less likely to be held up and can travel at a constant speed. Keeping to a constant speed will reduce the amount of pollution produced by your vehicle.

A full category D licence entitles you to tow a trailer of up to 750 kg.

Driving at higher speeds and for longer periods, such as on motorways, can cause your tyres to overheat and disintegrate. You should make a point of checking them when you stop for a break.

If you see a vehicle with a green flashing light, it will be a doctor on an emergency call, so give way by pulling over and letting the vehicle pass. But don't just stop suddenly - choose a safe place as soon as you can to let the doctor's car pass safely.

A road that has a steep camber will slope sharply towards the kerb, causing your bus to lean towards the pavement or verge. This brings a risk of collision with objects such as overhanging trees, lampposts and bus-stop roofs.

Make certain that your filler caps are properly closed, so that you don't spill fuel as you drive along the road.

When the roads are wet, have consideration for pedestrians walking or standing near the kerb.

Moisture in the braking system can cause serious problems, especially in cold weather, when it could freeze and stop the brakes from working. Most modern vehicles have a system that drains automatically, but make sure you know which system is fitted to any vehicle that you drive.

Normally, you should only use the hard shoulder for emergencies and breakdowns. On smart motorways, the hard shoulder may be used as a running lane, but only when speed-limit signs are shown directly above it. This technology has been introduced to ease traffic congestion.

If you've been stopped for some time at a bus stop or in a bus station, be aware that cyclists and pedestrians, especially children, can enter your blind spots. They may be out of sight below the windscreen line. Always take all-round observation before manoeuvring, whether you're moving away, parking or reversing.

Prompt treatment can help to deal with shock. Warning signs to look for include rapid pulse, sweating, pale grey skin, and rapid shallow breathing. While waiting for help to arrive, keep the casualty warm and comfortable, and speak reassuringly to them.

Always be aware of the height of the vehicle you're driving, particularly if you drive different vehicles. If you use a sat-nav, it may show you the height and weight limits on UK roads.

Be cautious, especially if there's a bend in the road and you're unable to see well ahead. If you have to pass pedestrians, leave them plenty of room. You might have to use the right-hand side of the road, so look well ahead and in your mirrors before you pull out.

Before leaving your vehicle parked, you must stop the engine. The parking brake must be set and the vehicle should be safe and secure when you leave the cab.

Learning is a process of practice and experience. Try to understand this and tolerate others who are at the beginning of this process.

Tyre care is especially important. You should routinely check tyre pressures and general tyre condition. An unroadworthy vehicle will endanger the lives of your passengers.
