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
• 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.
