Ignoring the 'No U-turns' (3c) sign is a traffic violation and can lead to dangerous situations, potentially causing accidents. It is a binding prohibition, and failing to comply can result in penalties and is a common point of confusion in the theory exam, where understanding all prohibitory signs is essential.
Generally, the 'No U-turns' (3c) sign indicates a strict prohibition. While additional panels might specify exceptions for certain vehicle categories or times, without such clarification, you must assume U-turns are forbidden for all vehicles. Always look for supplementary signs that might modify the restriction.
Lane markings often complement the 'No U-turns' sign. For instance, if a sign prohibiting U-turns is placed above a lane that is also marked with 'straight ahead only' arrows, it reinforces the restriction. Always consider both the sign and the road markings together for correct interpretation.
