How are detours
Detours are signposted using the signs on the right. Follow the signs to get back the motorway on which you were travelling. The signs along the detour route may have a white square (like the ones on the right) or another shape, such as a circle, or a triangle. Only one symbol will be used on each detour.
Take care to follow the signs staying on each road until the signs direct you onto another road. The end of the detour and the way back to the motorway will be signposted.
