LGV - Free Test #1

If you feel the onset of tiredness, you need to take a break. This might be at a motorway service station, but if there isn't one nearby you'll need to leave at the next exit and find a safe place to stop and rest.

If your vehicle is too long to fit into a passing place, you may need to wait opposite one. This will allow a following or approaching driver to pass. When you use this type of road, you need to plan and look well ahead to avoid meeting another road user at an inappropriate place.

Roll-over' usually happens as a result of the inside rear wheels of an articulated vehicle starting to lift when the driver changes direction sharply. This tends to happen when a driver is changing direction to leave a roundabout. If the load moves during the change of direction, the vehicle is increasingly at risk of rolling over. The problem often involves vehicles carrying fluids in bulk.

High-value cargoes are often targeted by thieves. Operators are recommended to seek advice from their local crime-prevention officer to help prevent their vehicles and loads from being stolen.

You should take account of the weather forecast when you plan your route. You're most likely to be subjected to side wind on exposed routes; for example, on long bridges, open roads and exposed stretches of motorway.

Fluids carried in tankers can move in waves as the vehicle's speed or direction changes. This happens particularly when you brake and then ease off the pedal; the moving wave of liquid causes the vehicle to surge forward. Baffle plates are designed to reduce this surging effect.

White boxes allow you to unload at any time, but during the day the length of stay is restricted. You should check nearby signs for the specific times. At other times, when it's not so busy, there may not be any restrictions on parking.

Unless the curtains are specifically designed, they must not be used to restrain the load. They should be used to protect it from the weather and provide a level of security. Most companies also use them as a mobile advertisement.

Demountable bodies have legs that can be lowered so that the carrier vehicle can be driven out from underneath the body. This has an advantage over ISO containers, which require some form of crane or lift to remove the container from the trailer.

On a quiet country road, always be aware that there may be a hazard just around the next bend, such as a slow-moving vehicle or pedestrians. There might not be a pavement and people may be walking on your side of the road.

Escape lanes are found on steep downhill sections of road. They're designed to give a 'run-off' area, usually straight ahead, to allow vehicles to stop in an emergency. This is usually when brakes have faded or failed on large vehicles.

Vehicles overtaking in the right-hand lane may return to the centre lane when they've finished their manoeuvre. You should look for this before starting to pull out. Don't rely on the size of your vehicle to claim right of way.

Correctly adjusted air deflectors will save fuel. They should be adjusted to guide the airflow over the highest point at the front of the trailer or load and body.

In an emergency, time can be of the essence. The emergency services need to know your exact location. Before you phone, get the post number from the nearest marker post on the edge of the hard shoulder. Give this to the emergency services, as it will help them to locate you.

Your tachograph chart is a legal document; it's a record of your work covering a rolling 24-hour period. Drivers who break the rules are subject to heavy fines and could lose their vocational licence. Altering your tachograph chart with intent to deceive is against the law and could lead to a prison sentence. Similar penalties exist for those who permit such offences.

These lights warn that children are likely to be crossing the road on their way to and from school. Slow down and watch out for them.

A kingpin or drawbar lock is a visible and effective deterrent to thieves wishing to steal an unattended trailer.

If the brake pedal is hard to press, this could mean a loss of vacuum or a fault in the vacuum pump. You shouldn't drive the vehicle until the fault has been repaired.

High vehicles are often directed to the centre of the road to go under an arched bridge. Check that your vehicle doesn't exceed the height restriction indicated. Plan your route in advance to avoid any bridges that your vehicle won't be able to clear.

Driving a large vehicle will sometimes require you to position your vehicle well to the left before making a tight right turn. Inexperienced drivers or riders may not realise your intentions and may try to overtake you. Make sure you signal in good time and make a final mirror check before committing yourself to the turn.

You'll need to identify the sign in time, so that you can select an appropriate gear.

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.

Don't try to enforce the speed limit by blocking another vehicle's progress. This is likely to cause the other driver to become more frustrated. Slow down or move over when it's safe and allow the other vehicle to pass.

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

Take care; it's not worth taking risks. Always check with your doctor to be absolutely sure. The medicine may have an effect on you later in the day and for longer than you think.

An unladen vehicle that also has high sides will be vulnerable to the effects of strong side wind. An evenly distributed load will help to keep the vehicle more stable, but the higher the vehicle is, the more it will be affected. Be aware that such a vehicle may become unstable or difficult to control in windy conditions.

At the scene of an incident, you should tell your passengers what has happened, while reassuring them that they're not in danger. Explain to them that the emergency services are dealing with it and they should remain on the coach.

Telephone calls can distract you, meaning that you're not in proper control of your vehicle. If you need to use a telephone when driving, find a safe place to stop first. Better still, use a phone answering service and listen to your messages at the end of your journey.

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.
