PCV - Free Test #3

To keep your Driver CPC, you need to take 35 hours of training every five years. This can be split into sessions of at least seven hours each, so you can take one training day a year over the five years if that suits you. The penalties for non-compliance are the same as those for driving without a licence.

As well as headlights and tail lights, large vehicles have additional lighting to help other road users see the size of the vehicle. All lights should be clean and working properly. Driving at night when your vehicle is poorly lit is dangerous for you and other road users.

The 'stop' sign is the only road sign that's octagonal. This is so that it can be recognised and obeyed even if it's obscured (for example, by snow).

The endurance brake (retarder) slows the vehicle without the use of the wheel-mounted brakes. However, care should be taken in slippery conditions, when the retarder's effect can be powerful enough to cause a skid.

If you've been convicted of drink- or drug-driving, statistically you're a risk to yourself and others on the road. For this reason, when you're able to drive again, insurance companies may charge you a high premium to insure your vehicle.

To prevent drivers from becoming distracted, TV or video equipment must be out of their sight. While passengers are being entertained, they can be sure the driver is concentrating on delivering them safely to their destination.

Under no circumstances should you attempt to move or drive a vehicle with an air leak in the braking system. Report the fault immediately, or arrange to have it repaired. Place a warning sign in the cab, telling other drivers not to drive the vehicle and why.

Where the road surface has been made slippery (for example, by spilt diesel fuel), motorcyclists are particularly vulnerable to skidding.

To prevent your wheels from locking, you'll need to brake very gently on ice. Give yourself as much room and time as possible to stop. If your front wheels lock, you can't steer, and that will mean you can't avoid any obstacle in your path.

Advanced stop lines allow cyclists to take a position ahead of other traffic. When the green signal shows, they then have the time and space to move off in front of the following traffic.

A triangular sign is a warning sign. Knowing this, you can prepare for the hazard ahead.

Always maintain a safe following distance from the vehicle in front. If another vehicle pulls into the gap, slow down to re-establish a safe following distance. Following too close is dangerous and places you and other road users in unnecessary danger; your view of the road ahead will be seriously reduced, and you won't be able to see or plan effectively.

High-sided vehicles such as box vans are affected by side wind, particularly when they're empty. Drivers should slow down and stay alert for other road users affected by the windy conditions.

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.

Coolant solution is also known as anti-freeze. It provides protection from freezing and also contains a corrosion inhibitor that prolongs the life of the cooling system. Remember to check the coolant level regularly.

This sign gives you advance warning of a junction where the permanent sign is obscured by roadworks.

If there's a risk that another vehicle could run into the back of your bus, you should move your passengers forward to a safer position.

In very wet conditions, tyres may be unable to clear all the water from their path. This can result in a layer of water building up between the road and the tyre - a situation known as aquaplaning. To regain control, ease off the accelerator and, as the vehicle slows, the tyres should regain their grip. It's safer to reduce the risk of aquaplaning occurring by driving more slowly in very wet weather.

You should always check all your spray-suppression equipment before a journey. Don't ignore it just because it's dry when you set out. The weather can change on the way.

On unlit roads, it's more difficult to see bends, junctions or dips ahead. This could prevent you from seeing oncoming traffic, pedestrians or cyclists. Unless the road is well lit or you're on a dual carriageway, ask yourself whether overtaking is absolutely necessary.

The most powerful and effective brake on the vehicle is the service brake, and this should be used in normal circumstances. Well-maintained brakes should apply an even pressure to all the wheels, providing an efficient, controlled stop.

Sulphur produces acidic gases. Diesel fuels with lower sulphur content have been produced to reduce exhaust emissions that harm both people and the environment.

It's dangerous to drive a vehicle with low air pressure. To alert you to this, all vehicles are fitted with a warning light and/or buzzer. Don't move your vehicle if this warning shows or sounds.

Fire can spread extremely quickly. Your priority is the safety of your passengers: you must get them off the bus straight away. If at all possible, disconnect electrical lines and cut off the fuel supply. Fire can destroy a vehicle very quickly.

In poor conditions, all braking should be controlled, in good time and when travelling in a straight line. Try to avoid braking and turning at the same time. Look well ahead to assess and plan your actions.

Buses carrying schoolchildren must display a distinctive yellow reflective sign on the front and rear, unless they're running a scheduled service for the general public. Buses displaying the sign are permitted to use hazard warning lights when they've stopped for schoolchildren to get on or off.

At bus stops, stop close to the kerb, where it's safe and convenient for your passengers to get on and off. Accelerating as you move off can easily unsteady a passenger. Try to wait until all passengers are seated or settled before moving off.
