A careless driver smashes into you. He gets cited for careless driving, pleads guilty and is convicted. Pretty good evidence of negligence for your injury claim, right? Maybe not.
In Oregon, a plea, judgment or conviction of a traffic crime is not admissible in a later civil trial arising from the same facts. See, ORS 41.905 and 153.108 (2). Even though the plea, judgment or conviction is inadmissible, the facts that led to the conviction are often admissible. Often prosecutors will happily share evidence that led to the conviction to help establish liability in the civil personal injury matter.
