Regulatory Signs: Practice Questions

Regulatory signs are generally circular with a white background, black symbols and a red frame, and ignoring them can lead to a fine. This large topic covers the STOP sign and its eight corners, the downward-pointing give-way triangle, maximum speed signs, no entry, no parking versus no stopping, bans on particular vehicle types, and limits on height, width, weight and axle load. It also includes no overtaking signs, end-of-restriction signs, the no-horn sign and customs stops, with scenarios that ask whether your vehicle may pass.
