ADI Free Test #1

Even an empty roof rack will create extra wind resistance and this in turn will increase the vehicle's fuel consumption; for this reason, remove a roof rack when it's not needed.

You should stay in the left-hand lane of a motorway unless overtaking. The right-hand lane of a motorway is an overtaking lane and not a 'fast lane'. After overtaking, move back to the left when it's safe to do so.

On occasions, other road users may make a mistake or lack judgement. When this happens, try not to let it annoy you. Don't react by showing anger, sounding your horn, flashing your headlights or shouting. A safe driver remains calm and makes allowances for others.

If you want to turn left and there's a cyclist in front of you, hold back. Wait until the cyclist has passed the junction and then turn left behind them.

A person with only one eye isn't considered to have a disability for the purpose of driving and will be issued with an unrestricted driving licence.

Double white lines along the centre of the road are usually found in places where there's a poor view ahead, usually caused by bends in the road. When the line nearest to you is solid, you may cross it to pass a stationary vehicle, providing that it's safe to do so.

When a candidate passes a practical driving test, their full licence is normally issued directly by the licensing authority. However, if this doesn't happen, successful candidates should apply for a full licence as soon as possible. The driving-test pass certificate is valid for two years; if a full licence isn't applied for within that time, the driver will need to retake their test.

On a motorway, all traffic should use the left-hand lane unless they're overtaking. Use the centre or right-hand lanes if you need to overtake. Make sure that you move back to the left-hand lane when you've finished overtaking. Don't stay in the middle or right-hand lane if the left-hand lane is free.

A transfer of knowledge is when links are made between previous experience and the new skills to be learned. For example, a pedestrian who can judge appropriate gaps in the traffic to cross the road can link this skill to turning right into side roads when they learn to drive. A good instructor will identify these links.

On a busy motorway, traffic may travel at high speeds despite the vehicles being close together. Don't follow too close to the vehicle in front. If a driver directly behind seems to be too close to you, increase your distance from the vehicle in front by slowing down gently. If the traffic in front slows, you'll be able to spread your braking over a longer distance. This will reduce the risk of the driver behind being unable to stop in the room they've allowed.

In some built-up areas, the speed limit may be reduced to 20 mph. Where there are traffic-calming features, the speed limit may be signed as a 20 mph zone with no repeater signs within the zone. Where there are no traffic-calming features, the 20 mph speed limit is signed at each end of the street and with repeater signs in between. Driving at a slower speed will help give you the time and space to see and deal safely with hazards such as pedestrians and parked cars.

Clearways are in place so that traffic can flow without the obstruction of parked vehicles. Just one parked vehicle can cause an obstruction for all other traffic. Don't stop where a clearway is in force - not even to set down or pick up passengers.

You mustn't drive in a bus lane when it's in operation. If the bus-lane sign shows no times of operation, then the lane is in constant operation.

To reduce the risk of wheelspin when moving off on a slippery surface, use a higher gear than normal. This will reduce the amount of torque transmitted to the driven wheels. Gentle use of the accelerator will also make it easier for the tyres to keep their grip.

If you suspect a casualty has back injuries, talk to them and keep them calm. Don't attempt to move them, as this could cause further injury. Call an ambulance at the first opportunity.

When following a large vehicle, you need to keep well back to help you to see around it. You can only judge whether it's safe to overtake when you have a clear view of the road ahead. If another vehicle comes past you and fills the gap, drop further back to keep a safe separation distance.

If your vehicle breaks down, use hazard warning lights as well as a warning triangle or other device to warn other drivers. It's even more important to do this in the dark. Warning triangles should be placed at least 45 metres (147 feet) from your vehicle and on the same side of the road. Don't use a warning triangle on a motorway.

In icy and snowy weather, your stopping distance will be up to 10 times further than in good, dry conditions. To reduce the risk of skidding, take extra care when braking, accelerating and changing direction.

Try not to panic if a tyre bursts while you're driving. Take your foot off the accelerator and avoid braking suddenly. Try to steer a straight course while holding the wheel firmly.

The closer a driver gets to the vehicle in front, the less they can see of the road ahead. The safety aspects of keeping well back to gain a better view need to be emphasised and practised. It takes a long time to overtake a long vehicle and a good view of the road ahead is necessary to see that there's enough room to overtake safely.

As you look through the rear of your vehicle, you may not be able to see a child because of their height. Be aware of this before you reverse. If you're uncertain whether a child is behind but hidden from view, get out and check it's clear before reversing.

Too much oil in the engine will create excess pressure and could damage the engine seals and cause oil leaks. Any excess oil should be drained off.

If you wish to carry a heavy load on your vehicle, it's your responsibility to ensure that the load is secure and the vehicle isn't overloaded.

Always use the Mirrors - Signal - Manoeuvre routine before turning at junctions. Just before turning right, make a final check for any traffic that may be overtaking you on your right, as the driver or rider may not have seen your signal.

These lights warn that children may be crossing the road to a nearby school. Slow down so that you're ready to stop if necessary.

The sign warning of loose chippings is often accompanied by a plate showing an advisory maximum speed. Stone chippings thrown up by tyres can damage vehicles, and pedestrians, cyclists and motorcyclists are more vulnerable. The loose surface will increase your vehicle's stopping distance and there's an additional risk of skidding.

A long vehicle may have to straddle lanes on, or approaching, a roundabout. This is to prevent the rear wheels from going up onto the kerb. If you're following a long vehicle, stay well back and give it plenty of room.

If your indicators don't turn off automatically, you must cancel them. This might happen after a slight deviation, where the movement of the steering wheel hasn't been enough to activate the auto-cancel mechanism. A signal that continues to show after it should have cancelled can mislead other road users.

A high-intensity rear fog light helps drivers behind to see that there's a vehicle ahead, even though its outline can't be seen due to fog.

Most pedestrian crossings are for pedestrians only, but the toucan crossing has been designed to be shared by both pedestrians and cyclists. You can expect to find a toucan crossing where a cycle route and a footpath cross a road at the same point.
