In a civil case against a drunk driver, it’s not necessary for the driver to be convicted of DUI. The standards of proof in civil cases are lower than in criminal cases. While a DUI conviction or guilty plea can be used as evidence, it is not the only way to establish the driver’s intoxication. Other forms of evidence, such as police reports and witness statements, can also be used. It is important to consult with an attorney who can help gather the necessary evidence and navigate the legal process effectively.
