Crossing the traffic lanes, not obeying traffic signs, and swerving in the road are some of the reasons you can get pulled over for suspicion of driving under the influence of alcohol (DUI), according to the Your Erie website.
So what happens when the officer tells you to step behind your vehicle to perform a field sobriety test?
You’ll be asked to follow the tip of a pen with your eyes, put through a heel to toe walk, and then perform a balance test, such as standing on one foot.
You are also given a breathalyzer test to determine how much alcohol is in your system, writes Your Erie.
Police say their reasons for every one of these tests to insure you’re OK to continue driving, or to arrest you for drunk driving.
Police can also use these checks for drugs in your system.
