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.

Road humps, chicanes and narrowings are all traffic-calming measures designed to keep vehicle speeds low. They're used to protect vulnerable road users near areas such as housing estates and shopping centres.

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

You must obey signals given by police officers, traffic officers, traffic wardens and signs used by school crossing patrols. When a police officer signals to you to stop, you should stop safely on the left and switch off your engine.

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.

You must stop and wait behind the white stop line when the red traffic light is showing. The white line is generally positioned so that pedestrians have room to cross in front of waiting traffic. Don't move off while pedestrians are crossing, even if the lights change to green.

You should only flash your headlights to warn others of your presence. Don't use them to
- greet others
- show impatience
- give up your priority.
Other road users could misunderstand your signal.

Most power steering systems only work when the engine is running. If the power steering system fails (or the engine cuts out), much more effort will be needed to steer the vehicle.

Some bus lanes only operate during peak hours and other vehicles may use them outside these hours. Make sure you check the sign for the hours of operation before driving in a bus lane. Where no hours are shown, the bus lane operates 24 hours a day.

Coloured studs are used to help you judge your position on the carriageway in poor visibility. Knowing which colour is used and where can help keep you safe. Amber studs are used between the right-hand lane and the central reservation on a motorway or dual carriageway.

Check all tyres (including the spare) at least once a week. Do it when they're cold and remember to refit the valve caps. The vehicle handbook will tell you if you need different pressures for different conditions. Remember: because it's so dangerous, it's an offence to use a vehicle with an improperly inflated tyre.

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.

'Coasting' is the term used when the clutch is held down or the gear lever is in neutral and the vehicle is allowed to freewheel. This reduces the driver's control of the vehicle because the engine isn't connected to the driven wheels. This removes the assistance of engine braking and the stability of a powered drive train.

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.

Cars are designed to have an aerodynamic shape; an empty roof rack causes drag and increased wind resistance. The increased wind resistance will waste fuel; it also increases emissions and causes unnecessary pollution to the atmosphere.

Check the vehicle handbook: this should give you guidance on the correct tyre pressures for your vehicle. There may be recommendations to increase the tyre pressure when carrying heavy loads or when travelling continuously at higher speeds, such as when using a motorway.

The brakes on your vehicle must be effective and properly adjusted. If your vehicle pulls to one side when braking, take it to be checked by a qualified mechanic. Don't take risks.

The edge of the carriageway is often marked with a continuous white line. This stops at junctions, lay-bys, and entrances and exits from private drives. In conditions of poor visibility, such as when it's foggy, this line can help you see the edge of the road.

A long white line with short gaps means that you're approaching a hazard. Don't cross the line unless you really need to. If you do need to cross the line, make sure that the road ahead is clear before doing so.

A properly adjusted head restraint can help to prevent whiplash injury to the neck and spine. You're most likely to suffer this type of injury if you're hit from behind by another vehicle.
