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.

Although cars are the least likely to be affected, side winds can affect anyone, especially
- after overtaking a large vehicle
- when passing gaps between hedges or buildings
- on exposed sections of road.

The speed limit on a dual carriageway or motorway is 70 mph for cars and motorcycles, unless there are signs to indicate otherwise. If your car or motorcycle is towing a trailer, then a lower national speed limit applies. The speed limits for different types of vehicle are listed in The Highway Code.

The purpose of this road marking is to keep the junction clear of queuing traffic. You may only wait in the marked area when you're turning right and your exit lane is clear but you can't complete the turn because of oncoming traffic.

On a single carriageway road, the national speed limit will apply, unless signs indicate otherwise. For a car, the limit is 60 mph unless the car is towing a trailer - in which case the limit is reduced to 50 mph.

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.

A mirror with convex glass has a wide field of vision but makes it more difficult to judge the distance and speed of traffic behind. Vehicles seen in this type of mirror appear to be further away than they actually are.

Before you enter a roundabout, you normally give way to any traffic approaching from your immediate right. In a few cases, however, traffic on the roundabout has to give way to traffic entering. Look out for 'give way' signs, road markings and traffic lights on the roundabout.

The flashing amber light allows time for pedestrians to finish crossing. If the crossing is clear and it's safe, you may drive on before the green light shows.

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.

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.

If your indicators don't turn off automatically, you must cancel them. This might happen after a slight deviation, where the movement of the steering wheel hasn't been enough to activate the auto-cancel mechanism. A signal that continues to show after it should have cancelled can mislead other road users.

When travelling down a steep hill, your vehicle will tend to increase speed. This will make it more difficult for you to stop. To maintain control and prevent the vehicle from running away
- select a lower gear - the engine will then help to control your speed
- use the footbrake to maintain control.

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.

Selecting a low gear when travelling downhill will help you to control your speed. The engine will assist the brakes and help prevent your vehicle from gathering speed.

To use anti-lock brakes in an emergency, you should brake firmly until you've come to a stop. The anti-lock mechanism will activate automatically if it senses the wheels are about to lock.

Road humps are there to reduce the speed of traffic. Don't accelerate between them, as their purpose is to slow traffic along the whole street. This is to protect vulnerable road users in the area.

A continuous white line is often seen along the edge of the road. Its purpose is to mark the edge of the carriageway. This can be helpful in conditions of poor visibility, such as when it's foggy or at night.

The entry sign to a controlled parking zone will show the times of operation. Inside the zone, yellow lines indicate where waiting is prohibited. Yellow time plates are provided where a yellow-line restriction operates at different times from those shown on the entry sign.

This sign indicates a route for trams only. Other vehicles aren't allowed to use these routes. Drivers need to look ahead and plan - especially in an unfamiliar area.
