Types of traffic signage can be divided into three categories:
-Regulatory
Regulatory signs notify motorists of traffic laws and regulations. These may include stop signs, speed limit signs and one-way signs.
-Warning
Warning signs are used to signal unexpected or dangerous conditions ahead that may require motorists or pedestrians to reduce speed or change routes. These may include slippery when wet signs, merging traffic and no passing zone signs.
-Guide signs
Guide signs are road signs which advise and inform road users about the route they are following. They give distances and directions to destinations, on the route or along other roads which intersect with the motorist’s route. These may include end freeway sign, exit signs and advance direction signs.
