Generally speaking, you should stick to the left lane if you want to take the first exit, and the right lane if you want to take the third (or subsequent) exit. If you're going straight, you can use either lane. Plus, you must give way to any traffic that's already in the roundabout.
Another good rule of thumb to follow, unless otherwise indicated by way of road signs, is to use the left lane up to the 2nd exit, or 180 degrees.
If you have a four-road roundabout, and your GPS says “take the second exit”, that basically means you should go straight (so you would skip the first exit on the right, and take the next one).
For the first exit, take the left-hand lane and for the final exit, take the right-hand lane, indicating your intentions appropriately.
If there are three exits on a roundabout and three lanes, each lane corresponds to an exit, with the first exist being the lane furthest to the left. The second exit is the middle lane, while the third is the lane on 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.
On a standard, 2 lane, 4 exit roundabout. When turning right (3rd exit) you indicate right and stay in the outer lane (the one closest to the roundabout) until you pass the 2nd exit, when you start indicating left to leave.
the first road sign tells us our lane of be splitting into two the left lane goes left and straight and the right lane will be turning right the second board gives us more information about the roundabout. so this roundabout has three exits. the third exit is on the right.
For all exits you must indicate left before you take the exit. Bear in mind that if you indicate left and don't take that exit that cars coming onto the roundabout just after that exit might think you are turning and could pull out in front of you.
If you can choose among three lanes on your side of the road, pick the middle lane for the smoothest driving. Use the left lane to go faster, pass, or turn left. Use the right lane to drive slowly, enter, or turn off the road.
The left lane is the default lane: you should always use it, except for when you're turning right or there is road signage that says otherwise. The right-hand lane(s)—yes, middle lanes count as well—are for overtaking and turning right.
Going straight ahead at a roundabout
Unless road markings indicate otherwise, you should use the left lane when going straight ahead. There's no need to signal on approach. Make sure you stay in your lane as you go around the roundabout. When you've passed the exit before the one you need to take, signal left and exit.
Position 2: The right side of the lane. This is a good place to go if someone is passing you. You're still within the lines of the original lane and haven't changed lanes, you're just shifted over to the right a bit to allow some extra space for the other driver to get by.
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.
Lane positioning
If your exit is before or at 12 o'clock, choose the left-hand lane. If the exit is after 12 o'clock, choose the right hand lane. This gets a little trickier when a roundabout has more than two lanes.
Exit discharges must lead directly outside or to a street, walkway, refuge area, public way, or open space with access to the outside.
As with all junctions and roundabouts, if you're in the wrong lane, move into the correct lane safely by use of mirrors, blind spot check and signalling only if it is safe to do so.
When taking an intermediate exit… You do not normally need to signal. Approach in the most appropriate lane and stay there until you need to change course. Change lanes when you need to leave. Signal left after passing the exit before the one you need.
the left lane will go left the middle lane will be going straight and left and the right lane will go straight and right we need to move into the right lane to go to the fourth. exit.
Motorways typically have three lanes: Lane one – the left lane – is for routine driving. Lane two – the middle lane – and lane three – the right-hand lane – are for overtaking. Keep to lane one unless there's a build-up of slow-moving vehicles in that lane, when you can move over to one of the other lanes.
