Ohio Serious Vehicular Crimes Defenses

People charged with Vehicular Homicide and Vehicular Assault in Columbus Ohio and the central Ohio area may wonder what are the defenses to those charges. The defense for each case must be tailored to the unique facts, but there are common strategies for these cases.

Below are the top 40 defenses to the allegation your driving caused the accident:

1. Not all evidence collected and/or photographed
