Common DUII Defenses Used in Portland

Illegal Traffic Stop

If the officer lacked reasonable suspicion to pull you over, all evidence gathered may be suppressed. Portland attorneys frequently challenge stops on procedural grounds.

Breathalyzer Accuracy

Breath test devices must be properly calibrated and maintained. Equipment used by Portland-area law enforcement must meet Oregon standards for admissibility.

Blood Test Chain of Custody

Blood samples must be properly drawn, stored, and transported. Any break in the chain of custody can make results inadmissible.

Rising Blood Alcohol Defense

Your BAC may have been below 0.08% while driving but rose above the limit by the time you were tested. This is especially relevant when there is a long delay between the stop and chemical testing.

Field Sobriety Test Errors

Officers must follow NHTSA standardized procedures for administering FSTs. Deviations can undermine the prosecution's case.
