The flashing lights of a patrol car and the request to step out of your vehicle can be overwhelming. In those moments, many people feel as though the outcome is already decided.
Field sobriety tests are often presented as clear proof of impairment, but the reality is far more complicated. These roadside evaluations are subjective, and the way they are administered or interpreted can significantly impact the results.
Understanding field sobriety tests
In Indiana, it’s illegal to drive while OWI (operating while intoxicated) if your blood alcohol concentration (BAC) is 0.08% or higher. To enforce these laws, police officers use field sobriety tests.
Field sobriety tests are physical and mental exercises that police officers use during an OWI stop to check for alcohol impairment. In Indiana, officers often rely on standardized field sobriety tests such as the walk-and-turn or the one-leg stand. These are designed to measure balance and coordination, all of which can be influenced by more than just alcohol. Fatigue, medical conditions or even the type of footwear a person is wearing can affect performance.
Because these tests are conducted on the side of the road, conditions are rarely ideal. Rough pavement, poor lighting or the weather can make it difficult for anyone to perform perfectly. Even nervousness and stress can cause mistakes that may be misread as signs of impairment.
When challenged in court, defense strategies often focus on the administration of the tests themselves. Officers must follow strict guidelines, and if those are not met, the results can be called into question. Demonstrating that a test was improperly given, or that outside factors influenced the performance, can weaken the weight of the evidence against you.
If you’re facing drunk driving charges, it’s important to remember that you still have options. Speaking with a knowledgeable legal professional can make a significant difference in protecting your future.
