Junction, Lane Discipline and Parking Rules
Junctions
At a roundabout, traffic already circulating has priority and approaches from your left. Give way to it and enter only when there is a safe gap; do not stop once you are on the roundabout. At a give-way line or junction, use the priority shown by signs and road markings, and remember the general fallback: if there is no priority marked, be prepared to give way to traffic on the priority road and to the right. Never enter a junction you cannot clear - blocking a box junction is an offence even on a green light. Give way to pedestrians already crossing when you turn.
Lanes
Keep right except when overtaking. The left lane is for overtaking, not for cruising. Choose your lane early, signal, check the blind spot, and complete the change smoothly; do not straddle lanes or weave. On a multi-lane road, stay in the lane that matches your intended exit and do not cut across marked chevrons or solid lines.
Parking
Park within marked bays, facing the direction of traffic. Do not park on pedestrian crossings, in front of hydrants, on pavements, across driveways, at bus stops or too close to junctions and corners. Observe kerb markings and the accompanying sign; a single yellow marking is not permission to stop anywhere. Reverse into a bay where possible - it is safer to leave forwards. Accessible bays require a valid permit.
Traps
A vehicle behind flashing headlights does not have priority; a driver waving you out does not remove your duty to check; and a green light does not entitle you to block a junction.
Rule of thumb: at any junction, if in doubt, give way - a two-second delay costs nothing.
