4th DUI in California: Felony Status, Penalties and What Affects the Case
In California, a fourth DUI within 10 years can be charged as a felony or a misdemeanor under Vehicle Code §23550. The possible penalties are serious, but they are ranges, not set results. The court case, the DMV, treatment requirements and monitoring each work separately.
