Theory Test #4

Follow the instructions given by the signs or by tunnel officials. In congested tunnels a minor incident can soon turn into a major one with serious or even fatal results.

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

The speed limit is reduced for vehicles towing caravans and trailers, to lessen the risk of the outfit becoming unstable. Due to the increased weight and size of the vehicle and caravan combination, you should plan well ahead. Be extra-careful in windy weather, as strong winds could cause a caravan or large trailer to snake from side to side.

Vehicles that are used to carry children to and from school will be travelling at busy times of the day. If you’re following a vehicle with this sign be prepared for it to make frequent stops. It might pick up or set down passengers in places other than normal bus stops.

If you want to overtake a long vehicle, stay well back so that you can get a better view of the road ahead. The closer you get the less you will be able to see of the road ahead. Be patient, overtaking calls for sound judgement. DON’T take a gamble, only overtake when you are certain that you can complete the manoeuvre safely.

A casualty suffering from shock may have injuries that aren't immediately obvious. Call the emergency services then stay with the person in shock, offering reassurance until the experts arrive.

If you’re travelling on an icy road extra caution will be required to avoid loss of control. Keeping your speed down and using the highest gear possible will reduce the risk of the tyres losing their grip on this slippery surface.

Long vehicles might have to take a slightly different position when approaching the roundabout or going around it. This is to stop the rear of the vehicle cutting in and mounting the kerb. Horse riders and cyclists might stay in the left-hand lane although they are turning right. Be aware of this and allow them room.

A green arrow indicates that the lane is available to traffic facing the signal. A white diagonal arrow means that the lane is closed ahead and traffic should move to the next lane on the left. A red cross means that the lane is closed to traffic facing the signal.

A last check in the offside mirror and blind spot will allow you sight of any cyclist or motorcyclist overtaking as you wait to turn.

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

At junctions your view is often restricted by buildings, trees or parked cars. You need to be able to see in order to judge a safe gap. Edge forward slowly and keep looking all the time. Don’t cause other road users to change speed or direction as you emerge.

Try to join the motorway without affecting the progress of the traffic already travelling on it. Always give way to traffic already on the motorway. At busy times you may have to slow down to merge into slow-moving traffic.

Hold back and allow the cyclist to move off. In some towns, junctions have special areas marked across the front of the traffic lane. These allow cyclists to wait for the lights to change and move off ahead of other traffic.

If you’re driving behind other traffic at night on the motorway, leave a two-second time gap and use dipped headlights. Full beam will dazzle the other drivers. Your headlights’ beam should fall short of the vehicle in front.

When approaching a tunnel, switch on your dipped headlights. Be aware that your eyes might need to adjust to the sudden darkness. You may need to reduce your speed.

After the casualty has been placed in the recovery position, their airway should be checked to make sure it is clear. Don't leave them alone until medical help arrives. Where possible do NOT move a casualty unless there's further danger.

The only time you are permitted to use your hazard warning lights while moving is if you are on a motorway or dual carriageway and you need to warn other road users, particularly those behind, of a hazard or obstruction ahead. Only use them long enough to ensure your warning has been seen.

There might be pedestrians crossing from in front of the bus. Look out for them if you intend to pass. Consider how many people are waiting to get on the bus - check the queue if you can. The bus might move off straight away if no one is waiting to get on. If a bus is signalling to pull out, give it priority if it’s safe to do so.

You should slow down and be cautious. The bridge is narrow and there may not be enough room for you to pass an oncoming vehicle at this point. There is also no footpath, so there may be pedestrians in the road.

If you’re following a cyclist who’s signalling to turn right at a roundabout leave plenty of room. Give them space and time to get into the correct lane.

In the event of a towbar failure the cable activates the trailer brakes, then snaps. This allows the towing vehicle to get free of the trailer and out of danger.

These lines are often found on the approach to a roundabout or a dangerous junction. They give you extra warning to adjust your speed. Look well ahead and do this in good time.

Be responsible and only drive if you are fit to do so. Some medication can affect your concentration and judgement when dealing with hazards. It may also cause you to become drowsy or even fall asleep. Driving while taking such medication is highly dangerous.

Before pulling up check the mirrors to see what is happening behind you. Also assess what is ahead and make sure you give the correct signal if it helps other road users.

The engine will need more power to pull the vehicle up the hill. When approaching a steep hill you should select a lower gear to help maintain your speed. You should do this without hesitation, so that you don't lose too much speed before engaging the lower gear.

If there is no-one on the crossing when the amber light is flashing, you may proceed over the crossing. You don’t need to wait for the green light to show.

Large, long vehicles need extra room when making turns at junctions. They may move out to the right in order to make a left turn. Keep well back and don’t attempt to pass on the left.

To prevent your lights from dazzling the driver of the car in front, wait until you’ve overtaken before switching to full beam.

In a contraflow system you'll be travelling close to oncoming traffic and sometimes in narrow lanes. You should get into the correct lane in good time obey, the temporary speed limit signs and keep a safe separation distance from the vehicle ahead.

These lines may be painted on the road on the approach to a roundabout, village or a particular hazard. The lines are raised and painted yellow and their purpose is to make you aware of your speed. Reduce your speed in good time so that you avoid having to brake harshly over the last few metres before reaching the junction.

Don’t be tempted to drive if you’ve lost or forgotten your glasses. You must be able to see clearly when driving.

Vehicle navigation systems can be useful when driving on unfamiliar routes. However they can also distract you and cause you to lose control if you look at or adjust them while driving. Pull up in a convenient and safe place before adjusting them.

These are small battery powered vehicles and include wheelchairs and mobility scooters. Some are designed for use on the pavement only and have an upper speed limit of 4 mph (6 km/h). Others can go on the road as well and have a speed limit of 8 mph (12 km/h). They are now very common and are generally used by the elderly, disabled or infirm. Take great care as they are extremely vulnerable because of their low speed and small size.

This sign indicates that there are waiting restrictions. It's normally accompanied by details of when the restrictions are in force. Details of most signs in common use are shown in The Highway Code. For more comprehensive coverage, see Know Your Traffic Signs.

While driving your concentration is required all the time. Even using a hands-free kit can still distract your attention from the road. Any distraction, however brief, is potentially dangerous and could cause you to lose control. Except in a genuine emergency, it is an offence to use a hand-held phone while driving.

This sign marks a route which buses are not permitted to use.

Congestion can be reduced by keeping traffic at a constant speed. At busy times maximum speed limits are displayed on overhead gantries. These can be varied quickly depending on the amount of traffic. By keeping to a constant speed on busy sections of motorway overall journey times are normally improved.
