PCV - Free Test #2

Your head restraint should be adjusted so that, in the event of a collision, it protects your neck from whiplash injury.

Drinking black coffee or waiting a few hours won't make any difference. Alcohol takes time to leave the body, so you should find a way to get home without using your vehicle; for example, by public transport. Depending on how much you've had to drink, you may even be unfit to drive the following morning.

Cold water will cool the burning tissue and help prevent further damage. It will also reduce swelling, minimise shock and alleviate pain. Use water, or any other liquid, that's clean and non-toxic.

Wet roads will increase the time it takes you to stop. Four seconds is the minimum gap you should leave on wet roads. This is double the gap you should normally keep from the vehicle in front on good, dry roads.

At the scene of an incident, first make sure there's no danger of further collisions or fire before dealing with any casualties. The priority when dealing with an unconscious person is to make sure they can breathe. This may involve clearing their airway if they're having difficulty or there's an obvious obstruction. Don't remove a motorcyclist's helmet unless it's essential, as you could cause them serious injury.

Stay back and allow the cyclist to proceed. You mustn't cut across in front of them. Also be aware of any cyclists who may try to pass on your left as you slow for the turn.

Flashing amber lights are found near schools. They warn you that children are likely to be crossing the road on their way to and from school. Drive slowly until you're clear of the area.

As the driver of a bus, you may be responsible for several passengers at any given time. If a situation occurs where you have to brake or steer harshly, your passengers could be thrown about the vehicle. In these circumstances, there's a significant risk of injury from fittings on board, such as luggage racks, handrails and poles. If seat belts are provided for passengers, they should wear them.

Toucan crossings can be used by cyclists and pedestrians. Some cycle routes lead cyclists to these crossings. Always look out for cyclists, as they're likely to be approaching much faster than pedestrians.

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.

In poor conditions, all braking should be controlled, in good time and when travelling in a straight line. Try to avoid braking and turning at the same time. Look well ahead to assess and plan your actions.

You should warn other road users that there has been a incident. You can do this by displaying an advance warning triangle or by switching on hazard warning lights or other lights. However you choose to warn people of the incident, make sure it doesn't put you or others at risk.

The entrances to roundabouts are often worn. This can make the surface slippery, especially when it's wet. You should plan your approach and brake in good time.

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.

Tailgating is very dangerous because there isn't enough room to stop if an emergency arises. It's also intimidating for the driver that you're following.

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.

Learner drivers are often nervous. If you stay well back, this will reduce the risk of incidents occurring if they make a mistake, and you won't intimidate them. Remember, you were once in that situation yourself.

Take extra care when you're driving on roads where trams operate. Look out for road markings and signs that tell you to expect them. Modern trams are very quiet and you might not hear them approaching.

If your suspension is damaged, all the weight of the vehicle compresses the road and anything located below it. The vibrations travel through the ground and can also damage surrounding buildings.

On motorways, there are often exposed stretches of road where vulnerable vehicles can be affected by side wind. A gust of wind can even blow a motorcyclist out of their lane. Try to anticipate how the wind may affect others and give them plenty of room.

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.

It's very important to know the correct fire extinguisher to use. They'll carry a coloured label or badge telling you their contents. Make sure you learn which extinguisher is which, as using the wrong one could be dangerous and may spread the fire further. For example, you should never use a water extinguisher on burning oil.

On a hot day, the fuel in your tank will expand. If this happens when the tank has been filled to the brim, fuel will spill onto the road. This can be very dangerous or even fatal for other road users - especially motorcyclists. Allow for this expansion when filling your tank.

Potholes and raised drain covers in the road can unsteady a motorcyclist. They may suddenly swerve to avoid these uneven surfaces. Watch out at places where the road is in poor condition and this is likely to occur.

If you've been stopped for some time at a bus stop or in a bus station, be aware that cyclists and pedestrians, especially children, can enter your blind spots. They may be out of sight below the windscreen line. Always take all-round observation before manoeuvring, whether you're moving away, parking or reversing.

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.

You can reduce the chance of a breakdown with routine maintenance and regular checks on your vehicle.

It can be dangerous for vehicles passing close by if you open the door carelessly. Always look properly to make sure that it's safe - checking the blind spots as well as using the mirrors - before you get out of the cab.

Anti-lock braking systems sense when the wheels are about to lock. The sensor control releases the brakes and immediately applies them again. It will do this many times per second. This both prevents skidding and enables the driver to steer - something that's impossible when the steering wheels are skidding.

It's illegal to drive a vehicle that's emitting excessive exhaust smoke, so you should get the problem fixed as soon as you're aware of it. Excessive exhaust smoke increases pollution and creates a hazard for other road users.
