LGV - Free Test #4

When a warning light or device indicating a loss of brake pressure comes on, you must stop safely and get the fault put right immediately. The safety of you, your load, your passengers and all other road users is at risk.

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.

At night, a pedestrian carrying a red light should be at the back of an organised walk. The walkers should keep to the left, but this won't always be the case. Pass them very slowly. Be aware that the pedestrians may have their backs to you and might not know you're approaching.

A motorcycle can be lost out of sight behind another vehicle. The use of the headlights helps to make the motorcycle more easily seen.

Every year, there are hundreds of incidents in the UK where vehicles hit railway or motorway bridges. Most involve buses, coaches and lorries. Make sure your route doesn't take you under a bridge that's too low for your vehicle. If you hit a bridge, you'll be putting yourself and any passengers at risk, and you could cause a major disruption to road and rail transport.

If there's nothing embedded in the wound, you can control the blood loss by applying pressure to the wound and raising the leg if possible.

Spray reducers or spray-suppression equipment are attachments fitted around the wheel arches of large vehicles. They effectively trap spray thrown up from the wheels, which would otherwise reduce visibility for other road users.

The priority when dealing with an unconscious person is to make sure they have a clear airway and can breathe. Stay with the casualty and make sure someone rings for an ambulance.

Goods and passenger vehicles with a MAM of more than 7.5 tonnes, those required to be fitted with a speed limiter, and vehicles towing trailers must not use the right-hand lane on a motorway with more than two lanes, unless there are exceptional circumstances.

While overtaking, you'll need to judge carefully when to return to the nearside lane. Check your left-hand (nearside) mirror to make sure the rear of your vehicle is well clear. You should allow for the length of both vehicles and take into account the speed difference. Don't cut in too soon on the vehicle you've overtaken, and don't rely on signals from other drivers; they may be signalling to someone else.

If you intend to turn right, check your right-hand (offside) mirror first. All of your mirrors should be properly adjusted to give a clear view around and behind your vehicle. They should be kept clean at all times and shouldn't be cracked or broken.

If you check the engine oil level when your vehicle is standing on a slope, the reading on the dipstick won't be accurate. Park it on flat ground, so the dipstick shows the true level.

Check all medicines for their side-effects, such as drowsiness. If you're unsure, ask your doctor or pharmacist to explain how you might be affected by the medication.

Modern large vehicles are fitted with power-assisted steering. If the steering feels heavy, then there's likely to be a fault, which should be investigated and repaired as soon as possible.

Lanes at roadworks often have weight restrictions to keep larger vehicles in the left-hand lane. The lanes through the roadworks are often narrow and therefore not wide enough for large vehicles to pass each other safely. Always look for restriction signs at roadworks. They're usually placed well in advance to give you time to move safely into the correct lane in good time.

When carrying high-value goods, you can become a target for thieves. Avoid developing a set routine or pattern. Vary your routes whenever possible to make it difficult for thieves to predict when and where your cargo can be intercepted.

There is a swing bridge or one that can open for boats at a river crossing ahead. Category: Warning signs.

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.

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.

Allow the cyclist plenty of room. Give them space and be prepared for them to change direction. To stay safe, they may travel around the roundabout in the left-hand lane.

Workshop manuals give detailed technical advice about the servicing, maintenance and repair of your vehicle. They're essential for anyone who wants to service or repair their own vehicle.

On smart motorways, the hard shoulder can be used as a running lane when a speed limit is shown above it. However, a red cross above the hard shoulder means that this lane shouldn't be used, except for emergencies and breakdowns.

Roadworks can involve complex lane layouts. Reflective green-and-yellow fluorescent studs are used to separate the lanes in a contraflow traffic system. As you approach roadworks, look for traffic signs giving you advance information, which may relate to the size or type of vehicle you're driving.

Learners might take longer to react to traffic situations. Don't unnerve and intimidate them by driving up close behind.

Standing on or near the edge of the carriageway is very dangerous. Your priority is to alert the emergency services by using an emergency roadside telephone. This connects to an operator, who'll get help out to you as soon as possible. In most cases, this is preferable to using a mobile phone, as it will show the operator your precise location.

When visibility is poor or the road is wet, leave a greater separation distance - at least a four-second time gap from the vehicle in front. You should also reduce speed and use dipped headlights.

Fragile loads need extra care in loading and handling. The load must be secured using the most appropriate form of restraint. Air suspension reduces the vibration caused by the impact of the lorry wheels on road surfaces. This also reduces damage to the road, bridges and adjacent structures.

If the trailer begins moving while you're working on it, you could put yourself and others in great danger. You must make sure that it's properly secured by the brake before you start work.

Poor planning leads to late braking and harsh acceleration. This causes higher fuel consumption and increased emissions, which is harmful to the environment.
