PCV - Free Test #3

Speed limiters may only be repaired by authorised speed-limiter centres. They'll ensure that all the connections are sealed and that the system is tamperproof.

If red lights flash on the overhead signals above your lane, you mustn't go past the signal in that lane. If other lanes aren't displaying flashing red lights, you may go ahead in those lanes if it's clear and you can move into them safely. If red lights flash on a signal in the central reservation or at the side of the road, you mustn't go past the signal in any lane.

When a police officer is following you and wants you to stop, they'll flash the vehicle's headlights and signal with the left indicator. You should stop in a safe place as soon as possible.

Even though the warning light is showing, there may be sufficient pressure to release the parking brake. However, you mustn't do this, because there may not be enough air pressure to operate the service brake.

The effect of your vehicle driving through a puddle will be to throw water onto the pavement. If there are pedestrians close by, they could be splashed with the water. Be considerate and, if it's safe to do so, avoid driving through the puddle.

To help a casualty who isn't breathing, you should remove any obstructions from their mouth and tilt their head back slightly. These actions will help to keep their airway clear and maintain the correct position if mouth-to-mouth resuscitation is required.

If there's a risk that another vehicle could run into the back of your bus, you should move your passengers forward to a safer position.

No phone call is important enough to endanger someone's life. If you must be contactable when driving, plan your route to include breaks where you can catch up on telephone messages in safety. Always choose a safe place to take a break.

Try to anticipate the actions of other road users. When you're waiting at a junction, don't emerge until you're sure of their intentions; their signals might be misleading.

On unlit roads, it's more difficult to see bends, junctions or dips ahead. This could prevent you from seeing oncoming traffic, pedestrians or cyclists. Unless the road is well lit or you're on a dual carriageway, ask yourself whether overtaking is absolutely necessary.

Never attempt to change direction to the right without checking your right-hand mirror. A motorcyclist might not have seen your signal and could have decided to overtake. This action should be a matter of routine.

Children getting off the bus will be hidden from your view, and they may not be able to see you. Even if they can see you, they may have poor judgement of danger. You should drive slowly as you pass the bus and be ready to stop.

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.

When passing through immigration control, you should have a list of all your passengers. They must all be accounted for.

All modern vehicles have some form of power-assisted steering, which will be able to cope with everything the vehicle requires. If the steering feels heavy, the power-steering system could be faulty and needs to be checked before you continue your journey.

Alcohol can take a long time to leave the body. You may feel all right to drive, but its effect will last for many hours.

Driving with the rev counter in the red band will cause the engine to wear prematurely and can lead to expensive repairs. This could result in the vehicle being off the road for some time.

You should allow the faster-moving vehicle to overtake safely. If you pull out to overtake at this time, you'll cause the car behind to brake sharply. Don't use the size of your vehicle to intimidate. Be professional and show consideration to other road users.

Elderly pedestrians may have impaired judgement, hearing and/or vision. Be aware that, if they do start to cross, they could take more time to do so.

It's a serious offence to drive without insurance. As well as an unlimited fine, you may be disqualified or given penalty points.

Always allow plenty of time for your journey, in case of unforeseen problems such as punctures, breakdowns, road closures or diversions. You'll feel less stressed and less inclined to take risks if you're not under time pressure.

When you have to straddle the lanes at small roundabouts or junctions, always signal in good time. Be alert for inexperienced road users who may, without realising, put themselves into a dangerous position.

Cyclists, motorcyclists, caravans and high-sided vehicles can be very vulnerable in high winds. Plan well ahead and consider the difficulties they may be having. Remember, some routes may be closed to certain vehicles and you may need to use an alternative route.

Many learners aren't confident when they first start to drive. Allow them plenty of room and don't react impatiently when they take their time. Remember that new drivers are inexperienced in dealing with traffic situations, so be patient.

Kneeling buses are equipped with air or hydraulic systems that allow the vehicle body to be lowered. This improves access for disabled and elderly passengers. Remember to return the mechanism to its travelling position before moving off.

Using a hand-held mobile phone while driving is illegal. It will distract you from your driving, because your attention is split between the phone call and your driving.

This mirror offers the most benefit when you're manoeuvring in confined spaces. It shows you where your nearside front wheel is in relation to the kerb or a bay marking line.

If you're travelling on a motorway and your view ahead is poor, then you should reduce your speed. Leave at least four seconds between your vehicle and the one in front, and make sure that others can see you by using your dipped headlights.

If you damage a parked vehicle and the owner isn't around, you must report it to the police within 24 hours. This applies to any property you might have damaged. In Northern Ireland, all incidents must be reported to the police immediately.
