Facing a first-time DUI in Pennsylvania can feel overwhelming. It’s a confusing and scary situation that can have a serious impact on your life. While the path ahead might seem uncertain, a DUI charge does not automatically mean a conviction.
Skilled legal representation can help build a proper defense depending on the circumstances of your case. An attorney can challenge the charges and work to protect your future and reputation. Here are potential legal defenses for a first-time DUI.
Challenging the traffic stop
Police officers must have a valid reason to pull you over, known as “reasonable suspicion.” It could be something like a broken taillight or erratic driving.
If the stop lacked a legal basis, the evidence collected afterward might be thrown out, including the results of any sobriety tests. Your attorney will investigate whether the officer had a lawful reason to stop your vehicle in the first place.
Are field sobriety tests reliable?
Field sobriety tests (FSTs) include the walk-and-turn, one-leg stand and Horizontal Gaze Nystagmus (HGN) tests. However, the results are often flawed. Many factors can affect your performance, such as:
- Medical conditions
- Weather conditions
- Your footwear
- Anxiety
An attorney can challenge how the officer administered the tests and question the results. Your performance could have been affected by conditions outside of your control. In Pennsylvania, you are not penalized for refusing to perform FSTs.
Contesting chemical test results
Breathalyzers and blood tests are designed to measure your blood alcohol content. But these testing methods are also frequently inaccurate. Issues can arise from improper equipment maintenance or mistakes made by the officer.
Your attorney can investigate potential problems with the tests, such as:
- Improper calibration of the breathalyzer machine
- Failure to follow proper testing procedures
- Improper handling or storage of blood samples
Your attorney will review all procedures and maintenance logs to find any errors that could have affected your results. However, it’s important to note that refusing a chemical test after a lawful arrest can result in an automatic license suspension.
Procedural violations and your rights
Even after a traffic stop, your constitutional rights must be protected. The police must follow specific rules and procedures at every step. If they don’t, it could lead to evidence being suppressed or your case being dismissed.
Your attorney will examine all police reports for any violations. They will look for whether the police had “probable cause” for your arrest or if your Miranda rights were read to you. They also check whether sobriety checkpoints are set up illegally. A violation of your rights at any stage could be a strong defense for your case and potentially lead to dismissed charges or lesser penalties.
