The C12 sign specifically prohibits the manoeuvre of performing a U-turn. You cannot turn your vehicle around to go in the opposite direction of travel at the location where this sign is posted or within the area it designates.
The restriction imposed by the C12 sign typically continues until it is explicitly ended by another traffic sign, such as a sign indicating the end of a prohibition, or it may be limited by additional panels. Always look ahead for signs that might modify or cancel the restriction.
Generally, the prohibition is absolute for the manoeuvre itself. However, some signs might have additional panels specifying if the prohibition applies only to certain vehicle types or under certain conditions. It's crucial to check for these panels and always follow the general rules of the road, such as not making a U-turn where it would be unsafe or illegal even without a sign.
A common trap is assuming the prohibition only applies at the exact spot of the sign. Learners might also confuse it with signs prohibiting a simple turn or forget to look for signs that cancel the restriction. The theory test will check if you understand that the C12 is a strict ban on reversing direction and requires you to find an alternative, lawful route.
If you see the C12 sign and need to change direction, you must continue driving until you reach a place where changing direction is permitted and safe, such as a junction where a U-turn is allowed, a roundabout, or a designated turning area. You might also need to make a three-point turn on a wider road if a U-turn is not feasible but changing direction is essential.
