PCV - Free Test #2

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.

All drivers may use hazard warning lights to warn other road users of danger on specific occasions. When you're driving a school bus, you may also use these lights when you've stopped and children are getting on or off the bus.

Air suspension provides a smoother journey than traditional suspension and transmits less vibration to the road surface, under-road services and nearby structures, such as bridges. It's considered to be environmentally friendly because it reduces damage to the road network.

Slow down and be ready to stop if you see animals in the road ahead. Animals are easily frightened by noise and by vehicles passing too close to them. Stop if signalled to do so by the person in charge of the animals.

You won't be able to see any hazards that might be out of sight in the dip. As well as oncoming traffic, there may be cyclists, horse riders, parked vehicles or pedestrians hidden from view. Only start to overtake when you can see the road ahead is clear, giving you enough time to overtake safely.

You should be aware that motorcyclists are likely to be affected by side wind and can be blown into your path. Adjust your speed so that you can stop or take avoiding action safely if necessary.

Buses carrying schoolchildren must display a distinctive yellow reflective sign on the front and rear, unless they're running a scheduled service for the general public. Buses displaying the sign are permitted to use hazard warning lights when they've stopped for schoolchildren to get on or off.

When you need to drive close to the kerb, be aware of the dangers.

• Pedestrians may step off the kerb.
• The nearside mirror may be at a pedestrian's head height.
• Cyclists may be tempted to pass you on your left if you're driving slowly in congested conditions.

If a school crossing patrol steps out into the road with a 'stop' sign, you must stop. Don't wave anyone across the road or get impatient and rev your engine.

The reverse warning bleeper is fitted to your vehicle to warn others near the vehicle that it's reversing. However, it's no substitute for good all-round observation. Get someone to guide you if you can't see clearly where you're reversing.

The car is the most stable of the vehicles shown. However, all vehicles are affected by side wind and buffeting from larger vehicles. Be aware that your speed and road position could cause unnecessary turbulence when passing smaller vehicles.

Smart motorways are intended to reduce congestion and make journey times more reliable. In these areas, the hard shoulder may be used as a running lane to ease congestion at peak times or when an incident occurs. The variable speed limits shown in red circles are mandatory and help to keep traffic flowing at a steady speed.

Always look into the road you're entering. If pedestrians are already crossing, be considerate and give way to them. Don't wave or signal them to hurry; they have priority here.

In wet conditions, water can build up between your tyres and the road surface. This is known as aquaplaning and it will cause your vehicle to slide. Try to regain control by easing off the accelerator to gradually lose speed. Don't brake or steer until your tyres are gripping the road again.

This shared route is for pedestrians and cyclists only. Be aware that, when it ends, the cyclists will be rejoining the main road.

Driving today requires all of your attention, all of the time. Any distraction, however brief, is dangerous. This is why it's illegal to use a hand-held mobile phone while you're driving.

Operators must set up an 'effective system' to prevent the carriage of illegal immigrants. This should include documentation with advice on vehicle security and a list of checks to be made. These papers should be produced immediately if an immigration officer asks to see them.

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.

When you're stationary for any length of time (for example, in a traffic jam), switch off your engine. This will cut exhaust emissions and so help to protect the environment.

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.

Always be concerned for the safety of other road users. Be aware of the various factors and situations where you may have to take action to keep more vulnerable road users safe.

While moving, hazard warning lights may only be used on a motorway or unrestricted dual carriageway to warn drivers behind of a need to slow down, due to a hazard ahead.

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.

In slow-moving traffic, particularly on dual carriageways or motorways, always be on the lookout for motorcyclists who approach from behind and filter through narrow gaps between vehicles.

In very wet conditions, tyres may be unable to clear all the water from their path. This can result in a layer of water building up between the road and the tyre - a situation known as aquaplaning. To regain control, ease off the accelerator and, as the vehicle slows, the tyres should regain their grip. It's safer to reduce the risk of aquaplaning occurring by driving more slowly in very wet weather.

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.

Turning off the engine is safer and emits less fumes into the environment. Leaving the engine idling unnecessarily will also waste fuel.

Make certain that your filler caps are properly closed, so that you don't spill fuel as you drive along the road.

In the darkness, it will be difficult to assess the road ahead - especially if there are bends or hills, which may prevent you from seeing oncoming vehicles.

It's vital that you give yourself enough separation distance when driving on icy roads - ten times as much as in normal conditions. You should brake gently to reduce the risk of losing control.
