When you are on a highway or in a busy city street, there are many traffic control devices that make the road safe for pedestrians and motor vehicle drivers. Understanding the basic categories of these devices will help you stay more informed and aware while driving. It will also be helpful when you are asked what a certain device means at your next trivia night, and you can step in as the hero for your team.
The first category of traffic control devices includes those that direct and regulate the movement of vehicles, including bicycles. Some examples include directional signage that gives directions for specific points along the road, signs warning pedestrians of danger and lane markings. These devices are designed to be highly visible, and most have retroreflective materials to achieve maximum visibility, especially at night.
Another important category of traffic control devices is the ones that assign priority rules for various types of vehicles in an intersection or roundabout. Traffic lights are a well-known example, using green, yellow and red to tell motorists when they can proceed through an intersection without stopping. Other examples of these devices are signals that indicate the appropriate lane to enter at an intersection and lights that advise drivers when they may safely cross a roadway.
Work zone traffic control devices are those that direct the movement of vehicles around areas where road repair or construction is being done. These include a variety of implements such as traffic cones, barrels and water barricades. These are usually brightly colored, and they are easy to spot, even at a distance. They also serve to channel traffic in a particular direction, which is useful for preventing a motorist from making a wrong turn that could lead to a serious accident.
Finally, there are those traffic control devices that assist law enforcement or fire personnel. Some examples include markers that identify fire hydrant locations, speed measurement pavement markings and signs posting local non-traffic ordinances or civic organization meeting information. This group of traffic control devices helps keep law enforcement officers and firefighters on the job more efficiently.
