Regulatory signs are the ones with the force of law behind them. Ignoring a warning sign is careless; ignoring a regulatory sign is an offence, and the learner's licence test treats the difference as something you are expected to know cold.
Almost all of them are round. A red ring around a black symbol prohibits something. A blue disc with a white symbol commands it. A red bar struck through the symbol ends a restriction that was set earlier. The two exceptions are the octagonal STOP and the triangular YIELD, given their own shapes so that they can still be read from behind or in the dark, when the colour and the wording are gone.
The groups below follow the way the manual splits them, because that is the way the test asks about them: control signs first, then commands, then prohibitions, the limits and their de-restrictions, and finally the signs that reserve a lane or a stretch of road for one kind of vehicle.
In the test: A prohibition sign is a red ring; a command sign is a solid blue disc. If you remember nothing else about the round signs, remember that red forbids and blue instructs.
