How are DUI laws enforced?
Sobriety tests are used to detect drunken drivers. One type of examination is a law-enforcement officer’s observation of a driver’s motor- and mental-skill levels, such as the ability to count correctly, to walk correctly, and to talk coherently. If an officer believes that a DUI arrest is warranted after an initial observation, a breath test will be administrated either in the field or at a police station. This second test is to obtain a blood-alcohol concentration level. Any driver who has a BAC of .08 or higher as indicated by the second test is guilty of driving while drunk. A prosecutor will obtain a conviction of drunken driving in this case despite any claims by the driver and any witnesses that the vehicle was under control.
