Vehicle-class signs: prohibited: part 2: how to read them

This chapter teaches 7 signs from the official manual: Construction vehicles prohibited, Vehicles transporting dangerous substances prohibited, Abnormal vehicles prohibited, Rickshaws prohibited, Tour buses prohibited, Agricultural vehicles prohibited, Animal-drawn vehicles prohibited.

Read the wording and symbol on each sign carefully. They tell you who the sign applies to, where it applies and what you must do, and two signs that look alike can apply to different road users.

Key idea: Check who a sign applies to before deciding what it means for you.
