This page collects the signs from the 400 series that give priority instructions and mandatory directions: stop, give way, the traffic light "train" and "go" signs, roundabouts, one-way streets and keep-right signs.
Know them cold for the theory test: confusing "give way" with "stop" is a classic mistake. If a sign is not here, check the prohibition signs.
