How can you prove that police wrongfully stopped you for DUI?

On Behalf of | Jan 16, 2025 | Drunk Driving Charges

Police must follow certain legal standards when stopping a driver for suspicion of driving under the influence in Pennsylvania. They need a valid reason or “reasonable suspicion” to stop a vehicle.

This means they must witness specific behaviors or circumstances before assuming that someone might be driving while impaired. Without reasonable suspicion, the stop may violate the Fourth Amendment, which protects against unreasonable searches and seizures.

Examples of valid and invalid stops 

Valid reasons for a DUI stop might include swerving, running a red light, speeding or other clear violations of traffic laws. However, stopping a driver based on a hunch or an unsubstantiated suspicion does not meet the legal requirement. For instance, driving late at night or leaving a bar does not justify a DUI stop unless the officer observes signs of impaired driving.

Gathering evidence to challenge the stop 

Challenging a DUI stop begins with examining the officer’s actions leading up to the traffic stop. Dashcam or body camera footage can provide evidence of the officer’s observations and behavior. Witness statements from passengers or other drivers may also help support the claim that the officer lacked reasonable suspicion.

Traffic camera footage or evidence from the vehicle’s GPS system may also prove that no violation occurred. For example, this evidence might show the driver remained within their lane or stopped at a traffic signal as required.

Demonstrating a lack of reasonable suspicion 

Proving that the police lacked reasonable suspicion can help your case in court. Under Pennsylvania law, the prosecution cannot use evidence obtained from an unlawful stop against the accused. Successfully challenging the stop may weaken or entirely dismiss the DUI case.

It is important to fully understand your rights during and after a traffic stop. This will help you know how the law protects you from improper police actions. You can defend yourself by recognizing and challenging any wrongful actions by law enforcement.
