Proof that a driver was intoxicated at the time of an accident does not automatically demonstrate negligence in personal injury cases. However, it often results in an admission of general liability if the drunk driver caused or contributed to the car accident. Injured claimants may establish drunk driving with the following evidence: A related DUI plea or conviction A blood alcohol test over 0.08 or indicating the presence of alcohol A breathalyzer test over 0.08 or indicating the presence of alcohol Witness testimony Victim testimony Traffic camera footage Restaurant security videos Physical evidence from the vehicle, such as open liquor bottles Prosecutors may share evidence with injured victims after a DUI conviction, including offender testimony and test results. Seattle drivers waive medical privacy rules related to alcohol and drug testing after car accidents, but personal injury attorneys must follow specific protocols for obtaining this evidence.
