1When turning into a side road, which road user should an instructor expect the driver to give priority to if they are crossing or waiting to cross the road being entered?
A.Traffic behind the car
B.Pedestrians at the junction
C.Drivers waiting in the side road
D.Cyclists only if they dismount
Explanation: The Highway Code gives pedestrians priority when they are crossing, or waiting to cross, a road into which a driver is turning. An ADI should teach pupils to scan both pavements, reduce speed early, and be prepared to stop before committing to the turn.
2On a dry road, what minimum time gap should normally be left between your vehicle and the vehicle ahead?
A.One second
B.Two seconds
C.Four seconds
D.Ten seconds
Explanation: The two-second rule gives a basic safety margin on dry roads. The gap should be increased in poor weather, at higher speeds, or when visibility and road surface conditions reduce the driver's ability to stop safely.
3Before signalling or changing direction, what routine should a pupil be taught to use?
A.Signal first so others know the intention, then check mirrors
B.Check mirrors, assess the situation, signal if it will help, then manoeuvre
C.Brake sharply, signal, and look over the right shoulder
D.Move position first, then signal if anyone reacts
Explanation: Drivers should use mirrors before changing speed or direction, then signal only when it will inform or help other road users. The routine prevents signals being given blindly and helps the driver decide whether the manoeuvre is safe.
4A learner intends to turn right at a standard roundabout. Which approach is normally correct unless signs or markings show otherwise?
A.Use the left lane and signal left on approach
B.Use the right lane, signal right on approach, then signal left after passing the exit before the one required
C.Use either lane without signalling until leaving
D.Drive around the outside of the roundabout to keep away from faster traffic
Explanation: For a right turn at most roundabouts, the normal routine is to approach in the right lane, signal right, maintain correct position, and signal left after passing the exit before the one to be taken. Local signs and road markings override the general pattern.
5When may a driver normally use the hard shoulder on a motorway?
A.To overtake slow-moving traffic
B.To stop in an emergency or when directed by signs or authorised personnel
C.To take a mobile phone call
D.To rest when tired if the services are full
Explanation: The hard shoulder is primarily for emergencies and for situations where signs, police, or traffic officers direct drivers to use it. It is not a spare lane and should not be used for convenience.
6On a narrow road with parked vehicles on your side, what is the safest general approach when meeting oncoming traffic?
A.Accelerate through the gap before the oncoming vehicle arrives
B.Give way if the obstruction is on your side and only proceed when there is enough space
C.Drive halfway into the gap so the other driver must stop
D.Sound the horn continuously until the road is clear
Explanation: If the obstruction is on your side, you normally need to give way to oncoming traffic unless you have already safely committed. An ADI should coach early observation, speed control, and eye contact or clear positioning rather than forcing a priority claim.
7On a clear dual carriageway, what lane should a driver normally use when not overtaking or preparing for a right turn?
A.The right-hand lane
B.The lane nearest the central reservation
C.The left-hand lane
D.Any lane if the speed limit is being obeyed
Explanation: Drivers should normally keep to the left unless overtaking or following signs and markings for their route. Good lane discipline reduces bunching, prevents unnecessary lane changes, and keeps overtaking lanes available.
8What is the national speed limit for a car on a single carriageway road, unless signs show a lower limit?
A.40 mph
B.50 mph
C.60 mph
D.70 mph
Explanation: For cars, the national speed limit on a single carriageway is 60 mph unless signs impose a lower limit. The limit is a maximum, not a target, so speed must still suit visibility, road layout, traffic, and weather.
9Why should an instructor discourage pupils from waving pedestrians across the road?
A.It is illegal to make any hand signal to pedestrians
B.The pedestrian may rely on the signal without checking for other traffic
C.It always gives the pedestrian legal priority
D.It makes the vehicle's brake lights stop working
Explanation: A friendly wave can be misunderstood as confirmation that the whole road is safe. The safer coaching point is to stop where required, remain predictable, and let the pedestrian make their own decision after checking all directions.
10What should a driver do before opening a door into a road where cyclists may be passing?
A.Open it quickly so the cyclist can see the movement
B.Check mirrors and blind spots, opening the door only when it is safe
C.Rely on the cyclist to leave a large gap
D.Use the horn before opening the door
Explanation: Drivers and passengers should check carefully before opening doors because cyclists and motorcyclists can be seriously injured by a door opening into their path. Teaching the far-hand or Dutch Reach habit can encourage a shoulder check before opening.

ADI Part 1: Suggested Study Strategy

1Study the four official multiple-choice categories evenly; a high overall score still fails if any category is below 20 out of 25.
2Use The Highway Code and Know Your Traffic Signs as active teaching references, not just memorisation lists.
3Practise explaining rules as you would teach them to a learner, especially junction priority, vulnerable road users, pedestrian crossings, and speed management.
4Review DVSA ADI registration duties, trainee licence rules, standards checks, and professional conduct because these are easy to miss if you only revise ordinary learner theory material.
5Connect hazard perception practice to real instruction: identify developing hazards early and explain what change of speed, position, or direction would be needed.
6Track scores by category during practice so weaknesses are fixed before booking the £81 official test.
