4.4: RESPONDING TO TRAFFIC CONTROL SIGNALS

Traffic control signals keep traffic moving in an orderly manner and to indicate right of way. In many large cities, signals are linked electronically to and are controlled by computer. This sets up a grid work that allows traffic to move smoothly and adjusts to changes in traffic volume.

How Do You Know When to Stop or Move Your Car Through Traffic?
As a user of the highway transportation system, your movement, whether you’re a driver or pedestrian, is controlled by a series of traffic signals, arrows, flashing lights, pedestrian signals, or the directions of a traffic officer.

• Traffic Signals: Traffic Signals are located at intersections where the level of risk increases. Traffic signals may be vertical or horizontal, with from one to five or more separate lenses that give information to roadway users.

At a flashing signal you must either stop or slow down, depending on the color of the light. A flashing red signal means that you must come to a full stop. You must slow at a flashing yellow signal.

• Pedestrian Signals: In the city you’ll find pedestrian signals at busy intersections. They may have either words or signals telling pedestrians how to proceed. Pay attention to the pedestrians and your own traffic signal.

• Traffic Officer’s Signals: Keep in mind that a police officer can take the place of and overrule traffic control signals. When an officer is present you should follow the officer’s signals even if they go against those of an automatic traffic signal or stop sign.
