Purpose of highway sign system

The purpose of the highway system is to provide safe comfortable convenient transportation for people and goods. Traffic control devices and signs are an integral part of this system and provide the medium for the
road authority to communicate vital information to the motorist along the
highway. This is accomplished through the use of regulatory and warning signs, including signs outlining speed limits and other regulations pertaining to the safe operation of the vehicle. Of equal importance are the guide signs that direct motorists to their destinations and signs that provide information on the

Consistency in design is good practice, as it assists a driver to respond to conditions, situations, events and information in a consistent manner. It is therefore important that, whenever possible, signs are kept identical, or at least very similar, on travel routes throughout North America, within Canada and each province.
