Who has priority at an unmarked crossroads in the UK?

At an unmarked crossroads where there are no signs or road markings, the general rule is to give way to traffic approaching from the right. Always approach with caution, observe other vehicles, and be prepared to stop if necessary.

How do I signal on a large roundabout in Great Britain?

When approaching a roundabout, you must indicate left if taking the first exit. For any exit past the first, you should indicate right when passing the exit before the one you intend to take, and then indicate left as you pass your intended exit. For the last exit (directly opposite), you must indicate right when approaching and left as you pass the exit before yours.

What is the difference between a mini-roundabout and a large roundabout?

Mini-roundabouts are smaller and often have a central island that you only drive around if the traffic flow dictates. You do not need to signal when entering a mini-roundabout unless you are turning left or right from the start. Large roundabouts are more complex, usually with multiple lanes, and require clear signalling and lane discipline as described in the Highway Code.

When should I give way at a T-junction?

At a T-junction, if you are turning left or right, you must give way to traffic on the major road (the road that continues across the junction). If you are emerging straight ahead, you must still give way to traffic on the major road. Always check for signs and road markings which will indicate the primary road.

Can I overtake on a roundabout?

Overtaking on a roundabout is generally not advised and often prohibited by road markings or layout, especially on multi-lane roundabouts. Focus on maintaining your position, signalling correctly, and safely exiting. If you need to overtake, it should be done before entering or after exiting the roundabout, adhering to all other rules.

What are the rules for traffic light controlled junctions?

At traffic light controlled junctions, you must obey the signals. Red means stop, amber means stop if safe to do so before the line, and green means proceed if the way is clear. You must also respect any associated signs, such as 'no entry' or specific lane directions, even when the light is green.
