What are the different types of tests used by police officers during a DWI traffic stop?
Police officers may conduct field sobriety tests and/or chemical tests. The most common field sobriety tests include the one-leg-stand test, the walk and turn test and the horizontal gaze nystagmus (HGN) test. Officers may also conduct a finger to nose test or the Rhomberg stationary balance test. Chemical tests are more important in determining guilt of driving while intoxicated. The three most common chemical tests are a breathalyzer test, blood tests and urine tests. In many states, a chemical test is required if there is suspicion of a DWI. Refusing to take a chemical test will result in a suspension of your license.
