Which vehicle might have to use a different course to normal at roundabouts?

أي عربة تسلك طريقا مغايرا للطبيعي عند الدوار

Explanation: A long vehicle may have to straddle lanes either on or approaching a roundabout so that the rear wheels don't cut in over the kerb. If you're following a long vehicle, stay well back and give it plenty of room.
