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.

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.

Give way to buses if you can do so safely, especially when they signal to move off from a bus stop. Look out for people who've just got off the bus, as they may try to cross the road. Don't try to accelerate past before the bus starts moving, and don't flash your headlights; other road users may be misled by this signal.

The speed limit for a car on the motorway is 70 mph. Drive in the left-hand lane whenever possible. Only move to the right to overtake, even if you're travelling at the national speed limit.

Red flashing lights above every lane mean you mustn't go on any further. You'll also see a red cross illuminated. Stop and wait. Don't
- change lanes
- continue
- stop on the hard shoulder (unless in an emergency).

All warning signs are triangular, but the 'give way' sign is the only triangular sign that points downwards; this is to give it greater prominence as you approach a junction. When you see this sign, you must give way to traffic on the road that you're about to join.

When traffic lights are out of order, you should treat the junction as an unmarked crossroads. Be cautious, as you may need to give way or stop. Keep a lookout for traffic attempting to cross the junction at speed.

The traffic that's permitted to use a contraflow lane travels in the opposite direction to traffic in the other lanes on the road. This is to help public transport make full use of the road network in places that would otherwise be unavailable, such as one-way streets.

Over-inflated tyres will cause excessive wear along the centre of the tread. Check your tyre pressures on a regular basis, and when the tyres are cold.

The lane under a gantry signal showing a red cross with flashing red lights is closed to traffic. You shouldn't proceed past that point in that lane. Should other lanes be open, move to a different lane and proceed with care. If red signals are shown above all lanes, then all lanes are closed: you must stop and wait for the lights to change or until you're directed to move.

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.

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.

The flashing amber light allows pedestrians who are already on the crossing to get to the other side before the green light shows to traffic. Give way to them and only proceed when the crossing is clear.

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.

Curving direction arrows are often found painted on the road before solid double white lines and hatch markings; they indicate the direction you should pass them. They're also painted on the road on the approach to low arched bridges, to mark the route high vehicles should take.

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.

In a crash, the occupants of a vehicle can be thrown violently forward and then back again. The head restraint should be adjusted so that it gives maximum protection to the neck as the occupant is thrown backwards.

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.

Try not to panic if a tyre bursts while you're driving. Take your foot off the accelerator and avoid braking suddenly. Try to steer a straight course while holding the wheel firmly.
