Before entering a roundabout you must indicate if you are intending to exit left or right (if going straight ahead, don't indicate on entry). You must give way to all traffic that will cross your path from your right as you enter the roundabout.
On approach you must indicate right, and turn using the right lane, unless arrows show you can use other lanes to turn right. You must give way to all vehicles already on the roundabout. You must continue to indicate right as you turn. When you leave, you must indicate left, if practical.
Explanation: When going straight ahead at a roundabout, don't signal as you approach it. Indicate left just after passing the exit before the one you wish to take.
If the exit you require is 12 o'clock or before you need the left hand lane. If the exit that you require is after 12 o'clock, you need the right hand lane. Unless any road markings or signs say differently.
This broken white line is a reminder to give way to traffic from the right at roundabouts.
Choice of lane and signal
When approaching a mini-roundabout, treat it similar to a normal roundabout. Signal left if you intend on turning in that direction, signalling right if you intend on turning right and when travelling ahead, no signal should be applied.
Position your vehicle in the right lane, unless arrows on the road or signs indicate otherwise. Use your right indicator as you approach and enter the roundabout. Give way to all vehicles already on the roundabout. Before exiting, use your left indicator and follow the exit lane marking.
Generally speaking when approaching a “two lane” roundabout, treat it like a clock face. If the exit you wish to take is the 1st exit, or is before or at the 12 o'clock point then stay in the left lane.
There is no evidence to support this, other than the 'careless driving' argument. You should plan before you enter a roundabout and circling more than twice could be considered as careless driving. It is however, illegal to drive over a mini-roundabout, as they must be treated as an island in the road.
If you need to travel straight on through a roundabout, then you'll generally need to use the left-hand lane. However, in some cases, the left-hand lane might only be for left turns only, so look out for signs that indicate this. Larger roundabouts might also have a designated lane for driving straight over, too.
Any turn that exits the roundabout after 12 o'clock can be considered a right turn. - Use your right indicator as you approach and enter the roundabout. - Before exiting, use your left indicator and follow the exit lane marking. - Stop indicating once you have exited the roundabout.
These yellow lines are painted across the road to make you aware of your speed. Yellow lines are an extra warning to slow down, and you can find this road marking on the approach to large roundabouts and dangerous junctions.
All vehicles MUST pass round the central markings except large vehicles which are physically incapable of doing so.
The golden rule
You approach the roundabout from the 6 o'clock position, entering the roundabout by turning left so that you go around in a clockwise direction, while at the same time, giving way to traffic coming from your right, who are already on the roundabout.
Slow down really early and look as early as you can into the road on your right, and across the roundabout itself. By watching the traffic flow really early, you can sometimes manipulate yourself an opportunity to go, by timing your arrival at the roundabout when there is a gap.
If you are taking the first exit you should always be in the lane furthest to the left. If you are taking the last exit, or if you need to go all the way around and double back on yourself, you should be in the lane furthest to the right.
Signal right and approach the exit in the right hand lane. Keep to the right on the roundabout until you need to change lanes to reach your exit. Signal left after you have passed the exit before the one you intend to take.
Once clear, indicate a right turn and enter the roundabout in the innermost (right) lane. Once you have passed the third exit, change the turn indicator to the left and exit the roundabout in the left lane.
Give way. The most important rule – when entering a roundabout, give way to traffic on the roundabout, unless road markings or signs say otherwise. If the way is clear keep moving. Stopping at a clear roundabout slows traffic and can cause frustrating delays.
How Many Times Can You Legally Go Around a Roundabout? There is no legal limit to the number of times that you can travel around a roundabout. However, circling a roundabout more than twice may be considered careless driving. You should always try to exit a roundabout correctly after you first enter it.
