The reflective studs between the carriageway and the hard shoulder are normally red. These change to green where there's a slip road. They help you identify slip roads when visibility is poor or when it's dark.

Pedestrians and cyclists can both cross at a toucan crossing; cyclists are permitted to ride across.

Knowing the sequence of traffic lights allows you to plan your approach. This can help prevent excessive braking or hesitation at the junction.

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.

You may only stop on the carriageway of a motorway
- when told to do so by the police
- when a red cross with flashing red lights shows above every lane - in a traffic jam
- in an emergency or breakdown.

Long white lines with short gaps mean there's a hazard ahead. Often a warning sign will show you the nature of the hazard. Don't cross the line unless you can see the road is clear well ahead and you wish to overtake or turn off.

Automatic transmission sometimes changes up as you approach a bend, due to reduced pressure on the accelerator. To avoid this, slow down before you reach the bend, then accelerate gently as you turn.

Some junctions only have 'give way' lines. This is usually where there's relatively little traffic. 'Give way' signs, and/or road markings, show you that traffic on the road you want to enter has priority.

Exterior mirrors are designed to be convex. This gives a wide angle of view and helps to reduce blind areas. However, a vehicle behind will appear smaller and further away in a convex mirror, so it could be closer than you think.

Normally, a driver shouldn't stop or park on a road that has double white lines along the centre. However, you may stop for long enough to set down or pick up passengers, or to load or unload goods.

Driving a vehicle with a brake defect could be dangerous and may constitute an offence. Check the brake-fluid level regularly, using the high/low markers on the reservoir. If the fluid level is too low, it could result in loss of braking efficiency.

You may use hazard warning lights when you slow suddenly on a motorway or unrestricted dual carriageway, to warn traffic behind of a hazard ahead. Never use hazard warning lights to excuse dangerous or illegal parking.

At a level crossing, flashing red lights mean you must stop. If a train passes but the lights keep flashing, you must continue waiting. Another train will be coming.

If the road surface is loose, it's possible for the loose surfaces to slide over each other. A vehicle's tyres may grip the surface layer but this may slide across a lower layer. An anti-lock braking system would be less effective in this situation.

If your front wheels are out of balance, the steering will vibrate. You'll have to take your vehicle to a garage or tyre-fitting firm, where they can balance your wheels; it isn't a fault that will rectify itself.

Before you start a motorway journey, make sure that your vehicle can cope with the demands of continuous high-speed travel. To reduce the risk of your vehicle breaking down, check the oil, water and tyres before setting off. If you're travelling a long way, it's also a good idea to plan your rest stops in advance.

Chevrons are painted on the road surface to help you to judge a safe following distance. In good weather, at least two chevrons should be visible on the road surface between your vehicle and the vehicle directly ahead in your lane. Where there are no chevrons, you should use the two-second rule.

Yellow lines are painted across the road on the approach to some roundabouts. The lines are usually found on dual carriageways, where traffic speeds are higher, or at the end of motorway exit slip roads. They provide a visual warning to remind drivers to check their speed.

The 'max speed' plate advises the maximum safe speed for negotiating the hazard shown on the warning sign. Drivers should slow down, as the hazard can be deceiving; for example, a bend may be much sharper than it initially appears.

If you see a pedestrian with a dog that's wearing a yellow or burgundy coat, take care. The pedestrian may have hearing difficulties and so be unable to hear you approaching.

In general, the vehicle handbook will recommend higher tyre pressures for continuous high-speed driving; for example, on long motorway trips. Increased tyre pressures may also be recommended when the vehicle is carrying a heavy load or when towing a trailer.

This curved arrow on the road indicates the direction that traffic should pass solid double white lines that are coming up. These arrows are also used on the approach to hatch markings and low arched bridges. Sometimes the arrow may curve to the right.

Where there's a hidden dip (dead ground), you should be aware that there could be oncoming vehicles out of sight between you and the road in the distance. Don't start to overtake until you can see into the dip and know the road ahead is clear.

This sign means it's illegal to overtake. It may have a black-and-white plate telling you over what distance the prohibition applies. There will normally be a sign with an 'End' plate where the prohibition ends.

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.
