If you're making a long journey, plan a rest stop of 15 minutes for every two hours of driving. Motorway driving can be very tiring, especially for new drivers, and if you feel tired you'll need to find somewhere safe to stop. However, you mustn't stop on a motorway, hard shoulder or slip road except in an emergency or traffic queue. To find a safe place to stop, you'll need to leave the motorway at the next exit or stop at the next motorway service area.

After driving through flood water, it's important to make sure the brakes are working properly. Check for other traffic and, when it's safe, test your brakes. If necessary, dry them out by applying light pressure to the footbrake while driving along slowly.

Any vehicle stopped on the hard shoulder of a motorway is at risk from passing traffic. For this reason, don't attempt to make repairs to your vehicle while it's on the hard shoulder. Make your way to the nearest emergency telephone to call for assistance.

Check with your doctor or pharmacist if you think that the drugs you're taking are likely to make you feel drowsy or impair your judgement.

If your car is fitted with an anti-lock braking system (ABS), this will activate when you brake so hard that the tyres start to lose their grip on the road surface. At this point, the wheels would normally lock up and a skid would start. The ABS senses the wheel locking and releases the brake pressure just enough to avoid the skid. It then cycles through applying and releasing the brake pressure many times per second. This ensures maximum braking for the available grip is constantly applied without the wheels locking.

If you want to turn left and there's a cyclist in front of you, hold back. Wait until the cyclist has passed the junction and then turn left behind them.

If you feel drowsy while driving on a motorway, find a safe and legal place to park as soon as you can. This will mean either leaving the motorway at the next exit or pulling in at the next service area.

Always stay in the middle of your lane until you need to change course. This is even more important when in narrow lanes; for example, at roadworks. Be aware of large vehicles that may have to straddle more than one lane.

Catalytic converters are designed to reduce toxic exhaust emissions by up to 90%. They have a high normal working temperature and for this reason are inefficient when the engine is cold.

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

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.

An instructor needs to explain that taking effective observation means not only looking but assessing the situation and using sound judgement. These are skills that develop over time. To emerge safely, a learner driver may need a much larger gap in the traffic than an experienced driver.

If you operate the brakes when air is in the hydraulic system, they'll have a spongy feel and braking efficiency will be reduced. This is because the air in the system is being compressed as you brake; hydraulic brake fluid alone can't be compressed. If you notice there's a fault with your brakes, have them checked as soon as possible. Don't drive with faulty brakes.

The lights that control the crossing show to both directions of traffic. If a pedestrian from either side is still crossing when the amber light is flashing, you must wait.

At a puffin crossing, an electronic device will keep the red light showing until it detects that the pedestrians have reached a safe position. Don't proceed until the green light shows - and then, only if it's safe to do so.

An incorrectly adjusted head restraint will offer reduced protection against whiplash injury. When adjusting the head restraint, set it so that it's at least as high as the eyes or top of the ears.

At a crossroads where there are no 'give way' signs or road markings, no-one has priority, even if the roads are of different sizes. Approach slowly and only cross when the junction is clear.

Don't turn your vehicle around on a busy main road. It's safer to find a quiet side road where you can turn around and then rejoin the main road.

Normally, an overtaking manoeuvre is carried out by passing the slower vehicle on its right. However, on a congested motorway where traffic on your right is moving more slowly than you are, it's acceptable to continue in the same lane and pass vehicles on their left.

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

Before turning right onto a dual carriageway, make sure that the central reservation is wide enough to protect your vehicle. If it's not, you should treat the dual carriageway as one road and check that it's clear in both directions before pulling out. Otherwise, you could obstruct part of the carriageway and cause a hazard, both for yourself and for other road users.

Properly timed signals tell other road users what you intend to do. When you're turning right at a roundabout, signal left just after passing the exit before the one you wish to take. This helps drivers behind and also those waiting to join the roundabout.

When driving in traffic, keep within your lane. Driving in the centre of your lane ensures there's as much space as possible between you and the traffic on either side. You should always follow the lane markings, which are there for two reasons: they make the best possible use of road space and they guide the traffic.

When teaching your pupil the turn-in-the-road exercise, you should explain that having the car under control is only part of the procedure. They also need to be aware of other road users and know how to deal with them safely.

Traffic signs and continuous red lines painted along the edge of the road identify a Red Route. Parking is banned along these routes and enforcement officers have powers to remove any vehicle that's illegally parked. These powers are in place to ensure the route remains unobstructed and so help the free flow of traffic.

The effects of shock may not be immediately obvious. Keep checking on casualties and talk to them to reassure them. Signs to look for include
- rapid pulse
- pale grey skin
- sweating
rapid, shallow breathing.

When a vehicle is facing downhill, it will try to roll forward when the parking brake is released. Applying the footbrake before releasing the parking brake ensures control is maintained.

Stay with the casualty and talk to them confidently to reassure them. Avoid moving them unnecessarily, in case they're injured. Keep them warm, but don't give them anything to eat or drink.

If you follow another vehicle with your headlights on full beam, they could dazzle the driver. Leave a safe distance and ensure that the light from your dipped beam falls short of the vehicle in front.

Be sure that the gap in the central reservation is wide enough to protect your vehicle before moving into it. Once you're within the central reservation, wait for a safe opportunity to complete the crossing. Where the central reservation is narrow, treat a dual carriageway as one road. Wait until it's clear in both directions before emerging, otherwise your vehicle will cause an obstruction to one or more lanes of traffic.
