Highway Code Advice
184
On approaching a roundabout take notice and act on all the information available to you, including traffic signs, traffic lights and lane markings which direct you into the correct lane. You should:
Use Mirrors – Signal – Manoeuvre at all stages
Decide as early as possible which exit you need to take
Give an appropriate signal (see Rule 186). Time your signals so as not to confuse other road users
Get into the correct lane
Adjust your speed and position to fit in with traffic conditions
Be aware of the speed and position of all the road users around you
When reaching the roundabout you should:
Give priority to traffic approaching from your right, unless directed otherwise by signs, road markings or traffic lights
Check whether road markings allow you to enter the roundabout without giving way. If so, proceed, but still look to the right before joining
Watch out for all other road users already on the roundabout; be aware they may not be signalling correctly or at all
Look forward before moving off to make sure traffic in front has moved off
186
Signals and position:
When taking the first exit to the left, unless signs or markings indicate otherwise
Signal left and approach in the left-hand lane
Keep to the left on the roundabout and continue signalling left to leave
When taking an exit to the right or going full circle, unless signs or markings indicate otherwise
Signal right and approach in the right-hand lane
Keep to the right on the roundabout until you need to change lanes to exit the roundabout
Signal left after you have passed the exit before the one you want
When taking any intermediate exit, unless signs or markings indicate otherwise:
Select the appropriate lane on approach to the roundabout
You should not normally need to signal on approach
Stay in this lane until you need to alter course to exit the roundabout
Signal left after you have passed the exit before the one you want
When there are more than three lanes at the entrance to a roundabout, use the most appropriate lane on approach and through it.
In all cases watch out for and give plenty of room to:
Pedestrians who may be crossing the approach and exit roads
Traffic crossing in front of you on the roundabout, especially vehicles intending to leave by the next exit
Traffic which may be straddling lanes or positioned incorrectly
Motorcyclists cyclists and horse riders who may stay in the left-hand lane and signal right if they intend to continue round the roundabout. Allow them to do so
Long vehicles (including those towing trailers). These might have to take a different course or straddle lanes either approaching or on the roundabout because of their length. Watch out for their signals
