Even if a DUI conviction does not occur, a driver can still face liability charges in a civil suit. Prosecutors must prove a person’s guilt beyond a reasonable doubt in a DUI case because this is a criminal charge. However, you can prove civil cases for damages resulting from intoxication by overwhelming evidence of intoxication and its effects. So, a driver could avoid a DUI conviction because of a technicality related to their arrest, but you could still prove their intoxication to the court in a civil case.
