Police officers who suspect people of driving under the influence (DUI) offenses often start looking for evidence immediately. They may follow people in traffic to record their conduct. They may ask them questions to get them to admit that they consumed alcohol previously.
They can also request that the drivers submit to testing. The first testing that occurs is often field sobriety testing. Before officers can justify requesting a chemical test, they have to screen people for signs of intoxication. They need probable cause to arrest a driver.
What usually happens during field sobriety tests?
Drivers perform physical tasks
Field sobriety testing involves gauging an individual’s ability to perform certain physical functions. There are three field sobriety tests recognized as standard. Those tests include the one-leg stand test, the walk-and-turn test and the horizontal gaze nystagmus test.
Officers have people walk in a straight line, balance on one leg and follow an object with only their eyes. These tests help gauge the likelihood of chemical intoxication, although false positive results are possible. Medical conditions and even anxiety could impact test outcomes.
Police officers usually record field sobriety test procedures. They may then arrest those who fail the tests and request chemical testing. Drivers have the right to refuse field sobriety test requests. They may also be able to provide evidence about why they failed the tests.
Understanding what happens during a DUI traffic stop can help people reduce their risk of a conviction. Many people accused of drunk driving can avoid convictions if they have assistance while developing a criminal defense strategy.
