LGV - Free Test #6

Driving in a fuel-efficient manner means that you plan well ahead for hazards and react in good time. This can save fuel and is therefore good for the environment.

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.

Take care if you're driving an empty high-sided vehicle when it's windy. Watch for places where the conditions could suddenly change, such as a gap between buildings or when passing under a bridge. Reduce your speed and stay alert for other road users who are also affected by these weather conditions.

Power-assisted steering operates when the engine is running. If a fault develops, much greater effort is required to turn the steering wheel. Don't attempt to drive a vehicle if you're aware of a fault in the power-steering system.

The service brake is usually operated by the brake pedal. It's used to control the speed of the vehicle and to bring it to a halt safely. It may also incorporate an anti-lock braking system.

You must check the nearside mirror during and after overtaking a motorcyclist. Make sure that the rider is still in control and that your vehicle's draught hasn't caused them to lose their balance.

If you become aware that any part of your load is insecure, you must stop as soon as it's safe to do so. Resecure the load before continuing your journey. If this isn't possible, then you must seek assistance. Don't take risks.

If a height isn't shown on the bridge, the headroom (in the UK) will be at least 5 metres (16 feet 6 inches).

Even though a warning device indicates low air-brake pressure, you may still be able to release the parking brake. If you do this and start moving, the service brake may be ineffective and you may not be able to stop.

Plan well ahead and take care if you need to move out or straddle lanes due to the length of your vehicle. Other road users may not understand your reasons for doing this and may try to pass on your left. Check your mirrors before and as you turn. It's better to use extra space on the road you're leaving than to find there's not enough room when you turn in.

If you try to overtake another vehicle and realise that you're unable to complete the manoeuvre, ease off the accelerator and drop back behind the vehicle. If the vehicle you're trying to overtake is large, then it will take a long time to pass. You should assess whether you have the time and power to complete the manoeuvre before you try to overtake.

Children can be unpredictable, and when they're in groups they may fool around and push each other into the road. You should drive with extreme caution when you're near them. You need to be ready to stop suddenly.

If you're trying to resuscitate someone, it's important that you don't give up on them. Make sure that someone has called the emergency services and continue trying to resuscitate the casualty until medical help arrives.

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.

If you're carrying a load that consists of loose materials, it must be covered by suitable sheeting. You mustn't risk losing any part of your load. This could cause damage or injury to other road users, and you would be responsible.

Large vehicles can be fitted with various types of endurance brake (retarder). Make sure you're familiar with how the system operates on the vehicle you're using. Don't risk a crash or collision through ignorance.

Any medical condition that could affect your ability to drive a lorry or a bus safely may prevent you from holding a licence. These conditions include serious visual impairment, heart disease and some mental disorders. For more information about medical standards, you should contact the Drivers Medical Branch, DVLA, Swansea.

Horses and their riders will move more slowly than other road users. They might not have time to cut across heavy traffic to take up a position in the offside lane when they're turning right; it could also be hazardous for them to do so. Therefore, a horse and rider may approach a roundabout in the left-hand lane, even though they're turning right.

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.

The exit from a motorway is indicated by countdown markers. These are positioned 90 metres (100 yards) apart, the first being 270 metres (300 yards) from the start of the slip road. Move into the left-hand lane well before you reach the start of the slip road.

Causing excessive smoke is an offence and could contribute to causing an incident or collision. You could also end up creating serious traffic problems if your vehicle breaks down in a difficult location.

At motorway roadworks, some lanes may be narrower than normal and large vehicles may not be allowed to use those lanes. Look for weight-limit signs to check for any lanes that you can't use. Move to the appropriate lane in good time.

Caravans are relatively light but have a large surface area. This makes them vulnerable to the turbulence created by large vehicles travelling at speed. The blast of air can destabilise the caravan, causing it to snake, and in extreme cases they can be blown over.

Never return to the left-hand lane until you're sure that you're well clear of the vehicle you've just overtaken. Don't cut in too soon and don't rely on the other driver flashing you in. Make your own judgement about when it's safe to move into the left-hand lane.

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.

When braking, always maintain steady pressure on the brake pedal until the vehicle has stopped. This helps to reduce the 'wave effect' that can build up as the liquid load moves when the vehicle changes speed.

Plan well ahead to enable you to brake normally. Don't rely on anti-lock brakes to compensate for deficiencies in your driving.

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.

Tailgating' - travelling too close to the vehicle in front - is very dangerous, because it doesn't give you enough distance to stop safely. Leave at least a two-second gap in good conditions, and increase this to four seconds in wet weather.

At the scene of an incident, the first priority is to prevent any further collisions by warning traffic. You can warn other traffic by switching on hazard warning lights or displaying an advance warning triangle, or by any other appropriate means.
