LGV theory practice test 4

Explanation

If you change vehicles during the working day, you should take your chart with you and use it in the next vehicle. This isn't always possible, however, as charts produced by different manufacturers may not be interchangeable. In this case, you should use another chart, making sure that all the information for the day is recorded.

Explanation

You should always be aware of the amount of room your trailer needs when it's going around bends and corners. If you need to go onto the other side of the road, make sure there's no oncoming traffic before you move out.

Explanation

To achieve maximum stability, the load should be placed to keep the centre of gravity as low as possible. To do this, heavy items should be placed close to the centre line and spread over the full length of the vehicle. Lighter items should be placed along the sides.

Explanation

Overloading an axle has an impact on the environment, causing damage to road surfaces. You also risk a fine and driving penalties.

Explanation

Some highly dangerous chemicals have to be transported at prescribed temperatures. Drivers must be fully trained in the use of these specially designed, temperature controlled vehicles.

Explanation

HMRC can check the type of fuel you're using, and the type and legality of your load. Red diesel is dyed gas oil with a lower tax than regular diesel. It can only be used in agricultural and construction vehicles such as tractors. Red diesel mustn't be used in freight transport.

Explanation

Whenever you uncouple a trailer, you must work through the uncoupling process methodically. Start by making sure that the brakes are applied on both the vehicle and the trailer.

Explanation

Under EU rules, you must have a minimum daily rest of 11 consecutive hours. A reduced daily rest period is any period of rest of at least 9 hours, but less than 11 hours.

Explanation

At a traffic incident, the danger of further collisions and fire needs to be dealt with first. Then you should deal with injuries in this order airway, breathing, compressions and bleeding. Don't remove a motorcyclist's helmet unless it's essential to do so.

Explanation

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.

Explanation

Warn other traffic of the incident, without putting yourself or others at risk. Once the danger of further collisions is dealt with, call the emergency services. While you're waiting for them to arrive, keeping casualties or witnesses calm is important, but never offer a cigarette because of the risk of fire.

Explanation

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.

Explanation

If the steering becomes heavy, the power assisted steering may have failed. It's also possible that your vehicle has a puncture or the load might have shifted. You should stop safely, investigate the cause and call for help if necessary.

Explanation

Good forward planning will reduce fuel consumption and engine emissions. This will cause less wear on the vehicle and its tyres, as well as reducing environmental pollution.

Explanation

Fuel spilled on the road is a serious danger to other road users, especially motorcyclists. To prevent this from happening, make sure the filler cap is secure after refuelling.

Explanation

Be especially careful about moving casualties at the scene of an incident. Inexperienced handling of a casualty could cause more injury, or even prove to be fatal. Only move casualties if they're in danger for example, from fire.

Explanation

Low sulphur diesel reduces the levels of sulphur dioxide particles in exhaust emissions. It's widely available and makes a contribution to reducing emissions that are harmful to human health.

Explanation

Driving in heavy traffic needs 100 concentration. If you become lost, find a safe place to stop before checking a map or asking for directions. Don't risk losing concentration by glancing at a map while driving, even if you're in traffic that keeps stopping.

Explanation

It's a legal requirement that your tyres have at least the minimum permitted depth of tread and are in good condition before you start any journey. Make sure that you inspect them before setting off, and at regular intervals.

Explanation

It's a legal requirement that information about a vehicle's height can be seen by the driver from their seat. It's important to know the height of your vehicle so that you can avoid any height restrictions on your route.

Explanation

Use your air conditioning only when it's absolutely necessary. Running it continuously increases overall fuel consumption by up to 15.

Explanation

Following the vehicle manufacturer's guidelines for service intervals will enable worn components to be replaced before they fail. This will help prevent costly breakdowns.

Explanation

If you overfill the engine with oil, you could cause the engine to build up too much pressure when it's running. This could cause damage to oil seals and gaskets.

Explanation

An engine fire is serious. If the fire breaches the fuel lines, it can easily spread to the fuel tank. If that happens, both the vehicle and its cargo will probably be lost. Therefore, your priority is to shut off the fuel supply.

Explanation

Plan well ahead before overtaking. Be aware that a speed limiter may cause you difficulties when overtaking another vehicle, particularly when climbing a hill.

Explanation

Traffic calming measures are becoming more common. Look out for signs warning you of humps in the road ahead. If necessary, change your route rather than take risks.

Explanation

The type of suspension fitted to a vehicle will influence its resistance to roll over. Modern tri axle semi trailers fitted with single wheels on each side extend the tracking width available, making this the most stable configuration.

Explanation

Load security is extremely important. Make sure you park legally and, preferably, in a well lit area. Some lorry parks are patrolled regularly by the police or security services.

Explanation

Continuous high speeds on the motorway can cause the tyres to become hot and to shred. If you notice this happening, you must stop on the hard shoulder as soon as it's safe to do so. It's dangerous to drive a defective vehicle.

Explanation

Tyres are your lorry's only contact with the road. It's essential that this contact gives you the grip you need to control your vehicle at all times. For that reason, goods vehicles must have a tread depth of at least 1 mm across three quarters of the breadth of the tread and in a continuous band around the entire circumference.

Explanation

Getting out of the cab on the offside, directly into the road, can be hazardous especially if traffic is travelling at speed. Use your mirrors to check that it's safe to leave the vehicle. Be sure to use all proper footholds and hand grips when you leave the cab.

Explanation

It's important to stow away all your electrical cables and air lines safely to avoid causing injury to others. Connectors left lying around can be a trip hazard and can be damaged if they're run over by another vehicle.

Explanation

Noise, vibration, exhaust emissions and fuel consumption all contribute to the environmental impact made by a lorry. Good anticipation and forward planning will help to reduce these effects. Braking in good time saves fuel and so helps reduce exhaust emissions. It also helps reduce wear on the vehicle, its tyres and the road surface.

Explanation

The choice of restraint will depend on the load. For example, ropes are unsuitable for loads such as steel plates, as there's a danger of sharp edges shearing the ropes. For steel plates, chains must be used with a suitable tensioning device.

Explanation

All spare sheets and ropes carried on the vehicle must be tied down securely to prevent them falling onto the road, where they may be a hazard for other vehicles.

Explanation

It's important that you always select a place to park that's both safe and legal. Don't park on or too close to a pedestrian crossing or a school entrance this would restrict the view for drivers and pedestrians. Don't park at a bus stop either, because buses would then have to stop in the road, creating a hazard for other traffic and for passengers getting on or off the bus.

Explanation

Only overtake when it's safe to do so, and don't use the size of your vehicle to intimidate approaching traffic. When overtaking a cyclist, leave plenty of room and, before returning to the left, check in your nearside mirror to make sure you've passed them safely.

Explanation

If there's any danger that the load you're lifting with a crane is too heavy for ropes or straps, or that sharp edges on the load may damage them, you should use chains with compatible tensioners.

Explanation

If you're driving an articulated vehicle or a trailer combination, it's vital that you understand the rules that apply to coupling and uncoupling the brake lines. If you take a practical driving test with a trailer, you'll be expected to demonstrate this during the test. The lines are colour coded red is the emergency line, blue is the auxiliary line and yellow is the service line. They must be connected strictly in accordance with the correct procedure.

Explanation

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.

Explanation

Air deflectors reduce wind resistance by streamlining the vehicle. They're most effective when there's a headwind. The streamlining also reduces the vehicle's fuel consumption.

Explanation

Before leaving a construction site, check your vehicle for mud and for debris wedged between double rear wheels. It's important that you prevent any mud or debris from being deposited on the road, where it could be a danger to other road users.

Explanation

The red emergency line is common to both two line and three line brake systems. The other colours are.

Explanation

A tyre may burst or shred if it overheats. This could result in serious loss of control. Stop on the hard shoulder as soon as it's safe to do so and call for help.

Explanation

Make sure you have enough rest before you start a night shift. Driving at night can be tiring and you must be able to stay alert for the whole of your shift. Making sure that there's enough fresh air in the cab can help you to stay alert. Stale, warm air can dull your senses and cause drowsiness.

Explanation

Articulated lorries aren't allowed to drive in the right-hand lane of motorways with three or more lanes. The only exceptions are when an escort vehicle gives you a signal, when road signs indicate, or when directed by a police officer.

Explanation

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.

Explanation

A sleeper cab can create extra blind spots. Look out for vehicles just to the rear offside and nearside of your cab they could soon become hidden in your blind spots.
