PCV - Free Test #2

Only change lanes if doing so won't inconvenience another road user. Merging drivers have a responsibility to give way, if necessary, and not force their way onto the main carriageway. Planning ahead will ensure you're prepared to deal with these situations.

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.

If you can't produce your driving licence when asked to do so by a police officer, you may be asked to produce it at a police station within a certain time.

After overtaking, check your nearside mirror carefully before moving back to the left. Don't rely on the other driver flashing their headlights, because only you can make the decision that it's safe.

Always use the MSM routine when you're approaching a hazard. M - Mirrors: check the position of the traffic behind you. S - Signal: signal your intention to slow down or change course in good time. M - Manoeuvre: a manoeuvre is any change in position, from slowing or stopping the vehicle to turning off a busy road.

Sometimes other road users disobey the rules or make errors of judgement. Try to accept this calmly and learn from their mistakes.

Extra care is needed when driving in heavy rain. Reduce your speed and switch on dipped headlights. Tyres will have less grip on a wet road and it will take up to twice the distance to stop when compared with good dry conditions.

If you're involved in an incident in a tunnel, be aware of the danger this can cause to other traffic. You should immediately switch on your hazard warning lights and switch off your engine.

When diesel fuel spills onto the road, it makes the road surface extremely slippery. This can cause danger for all types of vehicle, but particularly for those with two wheels, which rely on their tyres' grip to remain upright.

You should always check all your spray-suppression equipment before a journey. Don't ignore it just because it's dry when you set out. The weather can change on the way.

Look out for signs giving you advance warning of height restrictions. As a professional driver, you should always know the height of your vehicle or load. If you aren't sure of the safe height, stop and check.

There are heavy fines for those convicted of bringing illegal immigrants into the UK. This can mean a fine for each illegal person carried. The fine can be imposed on each 'responsible person', including the vehicle driver, owner and hirer.

You should check your tyres as part of your routine check of the vehicle. A damaged tyre - such as one with exposed ply - can have a major effect on your vehicle's handling and will make it a danger to you and other road users.

Whenever possible, call the emergency services first. If you're able to give first aid, remember DR ABC. Check for Danger, then check the casualty for a Response. Check the Airway, and try to establish Breathing by gently lifting the chin up and forward. Give Compressions if necessary. Try to stop any severe bleeding. If you feel you aren't capable of carrying out first aid, consider taking some training. It could save a life.

You should remain in the left-hand lane unless you're overtaking other vehicles. Don't be inconsiderate and stay in the centre lane or other overtaking lanes when you've finished overtaking.

An unladen vehicle that also has high sides will be vulnerable to the effects of strong side wind. An evenly distributed load will help to keep the vehicle more stable, but the higher the vehicle is, the more it will be affected. Be aware that such a vehicle may become unstable or difficult to control in windy conditions.

Some bus lanes operate only during peak hours and other vehicles may use them outside these hours. Make sure you check the sign for the hours of operation before driving in a bus lane.

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.

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

Being as healthy and alert as possible will make you safer on the road. Take regular meal and rest breaks, and keep to foods that contain complex carbohydrates, such as bread and vegetables. These release energy slowly and will keep you satisfied for longer than foods with a high sugar content.

To make sure it's safe, you must use the mirrors well before you make any manoeuvre. For example, you need to use them before moving off, turning, overtaking, slowing or stopping, opening a door, or changing direction, lanes or speed.

Sulphur produces acidic gases. Diesel fuels with lower sulphur content have been produced to reduce exhaust emissions that harm both people and the environment.

If you're approaching a set of traffic lights and you can see they've been on green for a while, be prepared for them to change. Ease off the accelerator and be ready to come to a gradual stop if you need to. Don't try to beat the red light; it may change as you come closer, causing you to brake late and harshly. Think of your passengers.

Look out for signs above your lane or on the central reservation. These will give you importantn information or warnings about the road ahead. To allow for the high speed of motorway traffic, these signs may light up some distance from any hazard. Don't ignore the signs just because the road looks clear to you.

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

You need to know the length of your vehicle as well as its weight, height and width. Places where the length of your vehicle may be relevant are

• road tunnels
• level crossings
• ferries
• bridges.

Vehicles carrying schoolchildren display the 'school bus' sign to alert other drivers to the danger of children crossing the road. As the bus driver, you must make every effort to ensure the children's safety when boarding or getting off your bus, as well as during their journey with you.

Expect a motorcyclist who makes a quick glance over their shoulder to be changing direction. They should do this before turning. By observing this, you'll get an early clue of their intention.

When seat belts are fitted to your vehicle, they must be worn unless you hold a valid medical exemption certificate. People making deliveries or collections in goods vehicles are also exempt, when they're travelling less than 50 metres (162 feet).
