LGV - Free Test #6

Always be prepared to give way to overtaking lorries or buses. Maintaining your speed will only block the motorway to other traffic unnecessarily. You may find yourself in a similar situation if the limiter on your vehicle doesn't allow you enough speed to successfully overtake another vehicle.

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.

You must take 35 hours of training every five years to maintain your Driver CPC. This can be done at any time during the five years: all at once or split into sessions of at least seven hours each. The penalties for non-compliance are the same as those for driving without a licence.

If you're trying to resuscitate a casualty, don't give up until medical help arrives. Never assume that someone's dead. People who aren't breathing can survive longer than you may imagine when given chest compressions and mouth-to-mouth resuscitation.

Research shows that approximately 40% of SRVIs involve commercial vehicles. The consequences are usually very serious because of the size of the vehicle and the fact that there is no braking before the impact.

A person who's hysterical may do things that you wouldn't expect. Try to keep the distressed person calm and safe until the emergency services arrive.

Tiredness can seriously affect your concentration - even to the point of falling asleep. You always need to be alert so that you can safely deal with the constantly changing environment around your vehicle.

A loose brake pedal would suggest a serious loss of fluid from the hydraulic system. Don't drive your vehicle until the fault has been checked and fixed by a qualified person.

High-sided vehicles are severely affected by side wind because of the large surface area of the bodywork. The risk of loss of control is increased if the vehicle is unladen.

As you approach the children, consider whether you need to sound the horn as a warning. Always check your nearside mirror as you pass any hazards on the left, so that you know when your vehicle is clear of the hazard.

You should take precautions against dropping mud on the road, because it's a hazard to other road users. It's also an offence for which you could be prosecuted.

Never attempt to change direction to the right without checking your right-hand mirror. A motorcyclist might not have seen your signal and could have decided to overtake. This action should be a matter of routine.

Endurance brakes or 'retarders' help to control a vehicle's speed. They operate by applying resistance to slow the vehicle without using the wheel brakes, so avoiding brake fade. The methods used include: increased engine braking, exhaust braking and transmission-mounted devices.

A pelican crossing that goes straight across the road must be treated as one continuous crossing even if it has a central island. The lights controlling the crossing show to both directions of traffic. You must give way to pedestrians who are still crossing when the amber light is flashing.

All vehicles over 7.5 tonnes maximum authorised mass must have markings on the rear of the vehicle. These markings are rectangular and are coloured red and yellow. They're there to inform other road users of the characteristics of your vehicle. The markings should be kept clean so that they can be seen clearly at all times, especially at night and in poor visibility.

The pump creates a vacuum in the servo unit. This reduces the amount of pressure you need to apply to the brake pedal. Without this vacuum, it's extremely difficult to press the brake pedal down.

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.

In high winds, some exposed roads, bridges and viaducts are closed to high-sided vehicles. Plan your route with care and try to avoid these areas. Also plan an alternative route in case of road closure.

Some lanes are set aside for certain types of vehicle. Signs and road markings show the authorised vehicles in words or pictures. There's usually also a sign showing the times that the lane is in operation. Some lanes might only be in operation for a short time. Check the sign and only use the lane if you're allowed to do so.

If you attempt to move a casualty who has a spinal injury, it could cause further damage. Make sure an ambulance has been called for and talk to the casualty to keep them calm.

Driving at high speed on a wet motorway can throw up dense spray, making it very difficult for other drivers to see ahead. Driving more slowly reduces the amount of spray and this makes it safer for other drivers.

Some drivers might emerge from a junction when it's not safe to do so. In this situation, understand that other drivers might make mistakes. Don't intimidate them by driving aggressively to teach them a lesson.

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

If you're the first to arrive at an incident, further collisions and fire are the immediate concerns. Switch on your hazard warning lights to warn other traffic. Stop any running vehicle engines to reduce the risk of fire. Don't assume that someone else has called the emergency services - do it yourself. Don't move casualties trapped in vehicles unless they're in danger.

As a local-service bus driver, you may use the bus lane at any time. The restrictions apply to other road users, to keep the lane clear for you at peak times. Don't be tempted to speed when driving up the inside of slow-moving or stationary traffic. Be alert for pedestrians who may be trying to cross the road.

Continually using the brakes could cause them to overheat. When that happens, they become less effective. This is called brake fade, and it occurs most often when the driver has to control the vehicle's speed on a long downhill gradient. To help prevent brake fade, use the endurance brake (retarder) and a lower gear to keep the vehicle's speed in check, rather than the wheel-mounted brakes.

Before entering a tunnel, you should switch on your dipped headlights; these help you to see and be seen. In many tunnels, using headlights is a legal requirement. You should also remove your sunglasses before you drive into a tunnel.

Immediate treatment can help to reduce the effects of shock. Reassure the casualty and try to keep them warm and comfortable. Only move a casualty if it's necessary for their safety.

To make sure it's safe, you must use the mirrors well before you make any manoeuvre. For example, you need to use them before moving off, turning, overtaking, slowing or stopping, opening a door, or changing direction, lanes or speed.

When seat belts are fitted to your vehicle, they must be worn unless you hold a valid medical exemption certificate. People making deliveries or collections in goods vehicles are also exempt, when they're travelling less than 50 metres (162 feet).
