Traffic Control Devices
Using Appropriate Traffic Control Devices for Traffic Control
Traffic control devices are signs, signals or other marking devices which are used to regulate and guide traffic. They warn both cars and pedestrians of possible dangers on the street or highway. These devices are paramount for promoting highway safety and the efficient flow of traffic through construction or other dense traffic zones.
The Manual on Uniform Traffic Control Devices (MUTCD) is recognized as one of the most widely used standards for traffic control. If you are unsure whether your traffic control equipment is appropriate for the job, this document will help you with many of your questions. The latest edition was just updated in May of 2012 and is available online in pdf form with a ‘hot links’ version to make finding answers to your questions even easier:
