ADI Part 1 theory test practice questions

The white circular sign with a red border and no symbol means 'no vehicles', including ridden bicycles. It's always used with a plate: mostly 'no vehicles', but occasionally 'play street'. Exemptions and times of operation may also be shown on the plate.

Diagonal stripes or chevrons are painted on the road to help separate traffic lanes or vehicles turning right. When bordered by a solid white line, you should not enter the area except in an emergency. If the line is broken, you should not enter the area unless it's necessary and you can see that it's safe.

The sign shows a mandatory cycle lane, and drivers must not park or drive in it during its times of operation. The lane will be marked by a solid white line on the road. Where the cycle lane is advisory, it will be marked by a broken white line. There'll also be a similar sign that shows a bicycle on a blue background but without the lane represented. Do not drive in this lane unless it's unavoidable.

If your learner wants to overtake a long vehicle, they should stay well back so that they can see the road ahead. They should not

• get too close to the vehicle, as this will restrict their view of the road ahead

• get impatient; overtaking on a busy road calls for sound judgement

• take a gamble; only overtake when they can see that it's safe to complete the manoeuvre.

This sign means there are waiting restrictions on the road. There may be further details, for example a plate showing when the restrictions are in place or road markings. Waiting restrictions generally allow you to stop briefly to pick up or set down passengers and may allow you to load or unload goods.

At blind junctions, there's often a 'stop' sign. The 'stop' sign has been put there because the view into the main road is poor. Your pupil must stop because it will not be possible to assess the situation on the move, however slowly they're travelling.

This sign on the overhead gantry will be accompanied by flashing amber lights. The arrow directs you to move into the next lane. There might not be any visible signs of a problem ahead, but there might be queuing traffic or another hazard that you cannot yet see.

If your pupil's turning into a side road, pedestrians already crossing the road have priority. Your pupil should also give way to pedestrians waiting to cross. Do not let your pupil

• wave them across the road

• sound their horn

• flash their headlights

• give any other misleading signal - other road users may misinterpret the signal and your pupil might lead the pedestrians into a dangerous situation.

If a pedestrian is slow or indecisive, encourage your pupil to be patient and wait. Do not let your pupil hurry them across by revving the engine.

If a police officer or traffic warden directing traffic signals you to stop, you must obey them. They'll use the arm signals shown in The Highway Code. If they're controlling traffic where traffic lights have failed, react to their signal as though it had been given by the traffic lights.

A long vehicle, such as a lorry, a coach or a vehicle towing a trailer, may swing out to the right as it approaches a left turn. This allows the rear wheels to clear the kerb. Do not let your pupil try to filter through if they see a gap on the nearside.

Some bus lanes only operate 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. Where no hours are shown, the bus lane operates 24 hours a day.

If you want to overtake on a two-way road that has 3 lanes, you must consider that approaching traffic could be planning the same manoeuvre. When you've considered the situation and have decided it's safe, indicate your intentions early. This will show the approaching traffic that you plan to pull out. Some of these roads have solid white lines marked to allow for overtaking in one direction only, usually for uphill traffic.

This hatched area is bordered by broken lines; in normal driving, there should not be a need to enter or cross the hatched area. When exceptional circumstances arise (for example, the need to pass a temporary obstruction or a slow-moving vehicle), you may drive on a hatched area when you're sure that it's safe to do so. Where hatched areas are bordered by a solid line, you must not enter the area except in an emergency.

Where a motorway has a steep uphill gradient, slow-moving, large vehicles might get in the way of other traffic. An extra lane on the left may be provided for these slow-moving vehicles. It allows faster-moving traffic to flow more easily.

Some junctions have advanced stop lines with an area for cyclists to position themselves ahead of other traffic. Your students must stop at the first white line they reach. If they're unable to stop safely at the first line, they must stop at the second line, even though they'll be blocking the area reserved for cyclists.

If your pupil's driving along the motorway in the left-hand lane and you see traffic joining from a slip road ahead, you should ask them move to another lane if it's safe to do so. This can greatly assist the flow of traffic joining the motorway, especially at peak times.

This sign prohibits all motor vehicles. Only bicycles may pass it. However, a black-and-white plate underneath the sign may give exemptions; for example, 'except buses' or 'except for access'.

The slip road should be used to allow your student to accelerate until their speed matches that of the traffic already on the motorway. By doing this, they can join the motorway without affecting the progress of the traffic. At busy times, they may have to slow down to merge into slow-moving traffic. Teach your students to always give way to traffic already on the motorway.

This blue circular sign indicates a route available only to the class of vehicle shown. Plan ahead so that when you see the sign, you have time to take another route; this may be indicated by other traffic signs.

Serious incidents have occurred when vehicles or people on the hard shoulder have been struck by vehicles using the left-hand lane of the motorway. While using the emergency telephone, be alert and watch for approaching traffic.
