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.

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.

Keep well back and allow the cyclist room to take up the correct position for the turn. Don't get too close behind or try to squeeze past.

Elderly people may misjudge how far away you are and how fast you're travelling. This may cause them to step into the road when you would expect a pedestrian to wait. They may also walk slowly and so could take a long time to cross the road.

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.

If a bus is signalling to move off, give it priority as long as it's safe to do so. Look for pedestrians who have left the bus and may be trying to cross the road.

A red cross with flashing red lights above your lane shows that your lane is closed. You should move into another lane as soon as you can do so safely. If the signal shows above all lanes, you must stop and not go beyond the signal.

If you see a vehicle with a flashing green beacon approaching, it means the driver or passenger is a doctor on an emergency call. Allow it to pass when you can do so safely. Someone's life could depend on the driver making good progress through the traffic.

You should check the coolant level frequently, particularly before a long journey, and top it up as necessary. The need to top up often might indicate a leak or other fault in the cooling system. Have it checked by your garage or dealer.

It's recommended that you check all the lights on your vehicle on a daily basis and replace any faulty bulbs. Carrying spare bulbs and fuses in your vehicle will ensure you can replace a bulb as soon as you find it has failed.

A circular sign with a red border tells you what you mustn't do. If the circle contains a speed limit, you mustn't exceed the limit, whether the sign is temporary or not.

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.

You're responsible for making sure that anything you carry on your vehicle is fastened securely. The safest way to carry items on the roof is in a specially designed roof box. This will help to keep luggage secure and dry. Roof boxes also have less wind resistance than exposed loads carried on a roof rack, and this helps to reduce fuel consumption.

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.

Holding the clutch down or staying in neutral for too long will cause your vehicle to freewheel. This is known as 'coasting' and it's dangerous, because it reduces your control of the vehicle.

Letting your vehicle roll or coast in neutral reduces your control over steering and braking. This can be dangerous on downhill slopes, where your vehicle could pick up speed very quickly.

Strict controls on exhaust emissions require a catalytic converter to be fitted to the exhaust system of all new vehicles. Catalytic converters remove most of the carbon monoxide, oxides of nitrogen and unburned hydrocarbons from the exhaust gases.

Carrying a heavy load in a vehicle will change its centre of gravity. This will affect the vehicle's handling on bends, compared with when it's lightly loaded. It's your responsibility to make sure that your vehicle isn't overloaded and that any load is secure.

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.

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.
