What are some typical defenses used in DUI cases?

Challenging the legality of the stop or questioning the accuracy of the sobriety tests is a common and effective defense in DUI cases. This approach hinges on the principle that law enforcement officials must have a valid reason to stop a vehicle. If the stop was not conducted based on reasonable suspicion or probable cause, any evidence gathered as a result may be deemed inadmissible.

Additionally, sobriety tests, which can include field sobriety tests and breathalyzer results, must be administered correctly. If an attorney can demonstrate that the tests were not conducted according to established protocols or that the devices used were improperly calibrated, this can cast doubt on the validity of the evidence of impairment. Overall, these challenges can significantly weaken the prosecution's case, making them a staple in DUI defense strategies.
