ADI Free Test #2

There's an eyesight test for the Register of Approved Driving Instructors. The requirement is that an instructor must be able to read a number plate with letters and figures 79 mm high and 50 mm wide at a minimum distance of 26.5 metres (87 feet). This is a greater distance than the minimum legal requirement for car drivers.

The steady amber light will be followed by twin flashing red lights, which mean you must stop. An alarm will also sound to alert you to the fact that a train is approaching.

If there are double white lines along the centre of the road and the line nearest you is continuous, you mustn't cross or straddle the line, except in specific circumstances. These include to enter premises or a side road, or to pass a stationary vehicle. You may also overtake a bicycle, horse, or road maintenance vehicle, provided they're travelling at 10 mph or less. You mustn't park on such a road, but you may stop to pick up or set down passengers.

A mirror with convex glass gives a wide field of vision. This makes everything appear smaller and further away than it would look in a flat mirror.

In heavy rain, the road will be wet and there may be pooling surface water. This will reduce the grip the tyres have on the road and will at least double the distance it takes to stop. Take this increased stopping distance into account while driving. Double the separation distance you'd leave in dry conditions.

A continuous white line is used on many roads to indicate the edge of the carriageway. This can be useful when visibility is restricted. The line is discontinued at junctions, lay-bys, and entrances and exits from private drives.

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.

You must stop if there's a red cross with red lights flashing above every lane on the motorway. However, if the signs over any of the other lanes don't show this signal, you may move into one of those lanes and continue, if it's safe to do so.

It's illegal to drive or park in a cycle lane marked by a solid white line during its hours of operation. Parking in a cycle lane will obstruct cyclists; they may move into the path of traffic on the main carriageway as they ride around the obstruction. This could be hazardous both for the cyclist and for other road users.

Hatch markings bounded by broken white lines are designed to separate traffic lanes or to protect traffic turning right. Only drive into these areas if it's necessary and you can see that it's safe.

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.

If you brake while travelling in a straight line, the inertia of the vehicle tries to keep it moving forward. This moves the weight of the vehicle forward and onto the front wheels. This extra load on the front tyres will press them more firmly into contact with the road, giving more tyre grip.

Fully applying the parking brake whenever your vehicle is stationary is important with an automatic car. This will reduce the possibility of the car creeping forwards when it's in gear.

There's usually a 30 mph speed limit where street lights are less than 185 metres (600 feet) apart.

When approaching a zebra crossing, drivers should look out for pedestrians wanting to cross. If anyone is waiting, you should slow down and be ready to stop and let them cross.

Before you test the brakes, don't forget to check for traffic behind. If it's safe, drive slowly and gently apply the brakes until they dry out and work properly again.

When someone is injured, any movement that isn't absolutely necessary should be avoided, as it could make injuries worse. Unless it's essential to remove it, it's generally safer to leave a motorcyclist's helmet in place.

In windy conditions, care must be taken on open, exposed roads. A strong gust of wind can blow you off course. Watch out for other road users who may be worse affected. These include cyclists, motorcyclists, and drivers of high-sided lorries or vehicles towing trailers.

The traffic that's permitted to use a contraflow lane travels in the opposite direction to traffic in the other lanes on the road. This is to help public transport make full use of the road network in places that would otherwise be unavailable, such as one-way streets.

Take care if a vehicle is approaching from the right and giving a left signal. The driver may have forgotten to cancel the signal or may wish to stop just past the junction. Don't emerge until you're sure of their intentions.

If you're involved in a collision that causes damage or injury to any other person, vehicle, animal or property, you must stop and exchange details with anyone having reasonable grounds for requiring them. If you don't give your details at the time, report the incident to the police as soon as is reasonably practicable and in any case within 24 hours.

Wet weather will affect the time it takes for you to stop. If another vehicle pulls into the gap you've left, ease back until you've regained the stopping distance that's appropriate for the conditions.

You should approach mini-roundabouts in the same way as normal roundabouts. All vehicles must pass around the central markings except vehicles that are physically incapable of doing so, such as long vehicles or vehicles towing trailers.

Use a slip road to adjust your speed to match that of the traffic in the left-hand lane of the motorway. This will allow you to merge into a safe gap in the traffic. Give priority to traffic already on the motorway.

If possible, lay the casualty down. Once you're sure there are no objects in the wound, apply firm pressure using clean material. Raising the arm above the level of the heart will also help to stem the flow of blood.

At the start of their training, a pupil needs to understand why the seating adjustment is important. They should familiarise themselves with all seat adjustment controls; without assistance, pupils should be able to move the seat into a position where they can reach all of the important controls comfortably.

If you realise you've taken a wrong turn when you're driving in a one-way street, don't reverse or turn your vehicle around. Drive on and find another route.

If a medicine you need to take is making you feel drowsy, get advice from your doctor before driving.

To make it easy to recognise, the 'stop' sign is the only sign that's octagonal. The visibility from a junction where the 'stop' sign is used will be poor, even from the edge of the junction. You must stop and, if necessary, edge forward until you can see it's safe to drive out.

Potential driving instructors (PDIs) will have their eyesight tested at the start of their Part 2 examination. A number plate, where the letters and figures are 79 mm tall and 50 mm wide, must be read at a minimum distance of 26.5 metres (87 feet). If a PDI can't pass this test, their Part 2 examination will go no further. This won't, however, affect their licence to drive, as the ADI eyesight test standard exceeds the legal eyesight requirement.
