Definition - What does Sobriety Checkpoints mean?
Sobriety checkpoints are locations where police conduct routine stops that are done for the purpose of testing drivers for sobriety. The most common method of doing this is through breathalyzer tests. Other methods are used as well including asking the driver to walk in a straight line or repeat the alphabet both forward and in reverse. These stops are performed for the purpose of reducing the risk of damage by drunk drivers and drivers affected from drug use including prescription drugs.
Justipedia explains Sobriety Checkpoints
Sobriety checkpoints have been introduced in many places to stop or deter intoxicated driving to reduce the potential of substance-related traffic accidents. Through the implementation of sobriety checkpoints, the roads are deemed safer with the knowledge that there aren't as many intoxicated drivers on the road. It is a common misconception that sobriety checkpoints are put in place for the specific purpose of catching drunk drivers. While a high number of drunk or intoxicated drivers are tested through these checkpoints, there are many who fail these tests due to recreational and prescription drug use including medicinal cannabis in states where it is legal.
