If another driver wishes to travel faster than you, it isn't your role to try and stop them. Move to the left when it's safe and let them pass, even if they appear to be breaking the speed limit.

These lines are a device often found on the approach to a roundabout or a dangerous junction. They become closer together as you approach the hazard, warning you to slow down.

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.

When planning and delivering a lesson, it's important to remember that we all learn in different ways. Continuing to deliver in the same way, when the pupil is clearly not engaging or making progress, may reduce their motivation even further.

Wet roads will reduce your tyres' grip on the road. The safe separation gap of at least two seconds in dry conditions should be doubled in wet weather.

If there's no pavement, The Highway Code advises pedestrians to walk on the right-hand side of the road, which means they may be walking towards you on your side of the road. At night or in poor visibility, they may be very difficult to see, so where there are no pavements, be mindful that pedestrians may be in the road ahead.

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.

Cyclists approaching a roundabout in the left-hand lane may be turning right, but may not have been able to get into the correct lane due to heavy traffic. They may feel safer by keeping to the left all the way around the roundabout. Give them plenty of room and be prepared for them to take a different course to other traffic.

You should carry out frequent checks on all fluid levels. The brake-fluid level will fall as the friction material on your brake shoes or pads wears down. If it falls below the minimum mark on the fluid reservoir, air could enter the hydraulic system, and this will lead to loss of braking efficiency.

You may be difficult to see when you're travelling at night, even on a well-lit road. If you use dipped headlights rather than sidelights, other road users will see you more easily.

Horses can be startled by the sound of a car engine or the rush of air caused by a vehicle passing too closely. Keep well back and only pass when it's safe. Leave them plenty of room. You may have to use the other side of the road to go past. If you do, first make sure there's no oncoming traffic.

The lowest level of insurance cover you must have to drive on public roads is third-party liability. The third party is anyone you might injure or whose property you might damage. With this minimum level of insurance cover, you're not covered for any damage to your vehicle or injury to yourself.

The thinking distance is the distance that the vehicle travels from the moment the driver realises there's a need to brake, until they actually begin to apply the brakes. This reaction time can increase if a driver is tired or unwell.

Before you move out to overtake, you must be sure that it's safe to complete the manoeuvre - and in order to be sure, you must be able to see far enough ahead. If anything is obstructing or restricting your view, you can't know whether the road ahead is clear and, therefore, you shouldn't overtake.

Learning isn't always a continuous process. Sometimes pupils simply need time to consolidate learning before moving on. On other occasions there may be something blocking progress. You should work with the learner to understand what's happening and agree how to move on.

The fuel in your vehicle can be a dangerous fire hazard. A strong smell of petrol may indicate a fuel leak and needs investigating. Don't use a naked flame near the vehicle if you can smell fuel, and don't smoke when refuelling your vehicle.

If you don't switch off rear fog lights when the fog has lifted, drivers behind may find it difficult to see your brake lights. This can be a particular problem on wet roads and on motorways. If you leave your rear fog lights on at night, drivers behind are likely to be dazzled and this could put you both at risk.

A 16 year old may drive a car if they're in receipt of the enhanced rate of the mobility component of Personal Independence Payment. However, if the enhanced rate is withdrawn, the normal minimum age for driving a car (17 years old) will then apply.

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.

It's not easy to see cyclists and motorcyclists, due to their small size when compared with other vehicles. At junctions, it's important that you look for these small vehicles; they're easy to overlook and riders are very vulnerable to injury in a collision.

Black ice makes a road look damp, and you may not be able to see that it's icy. Signs that indicate you may be on black ice include
- your steering suddenly feels light
- a lack of road noise from your tyres.

When giving cardiopulmonary resuscitation (CPR), continue until the casualty is breathing unaided or until medical help arrives. Don't give up. Look for signs of recovery and check the casualty's pulse. Avoid moving them unless it's necessary for their safety.

Using a lower gear will allow the engine braking to assist the brakes in keeping the vehicle's speed under control. Avoid coasting with the clutch held down or rolling in neutral, as there will then be no engine braking.

Slow-moving vehicles, such as a salt spreader or breakdown vehicle, may use a flashing amber beacon. On unrestricted dual carriageways, vehicles with a maximum speed of 25 mph (40 km/h) or less must use a flashing amber beacon.

If you're driving at night or in poor visibility, tinted lenses will make everything appear darker. This will make it more difficult for you to see in what are already difficult conditions.

If someone's been injured, the sooner proper medical attention is given, the better. Either ask someone to phone for help or do so yourself. Only move an injured person if there's a risk of further danger. Don't remove an injured motorcyclist's helmet unless it's essential.

You need to allow extra room in case the side wind blows the rider across the lane and into your path. Additionally, the draught from your vehicle could further buffet and unbalance the rider.

If a driver makes a mistake and emerges from a side road into your path, you should show tolerance and not react aggressively. If you're shaken or upset by the experience, slow down and - if necessary - stop in a convenient place. Take a break until you can safely continue on your journey.

As you approach left-hand bends, keep to the middle of your lane. Don't move to the centre of the road to improve your view. This could put you too close to oncoming traffic. A vehicle coming the other way might be running close to or over the centre of the road as it comes around the bend.

If an ADI is charging for a driving lesson, they must display their ADI certificate and appropriate L or D plates on the tuition car.
