What is the difference between a DUI felony, a misdemeanor, and an infraction?

A DUI felony is considered the most severe classification of DUI offenses in California which can result in serious punishment and penalties. A DUI felony involves 4th DUI offense in 10 years, DUI with a minor involved or causing an injury while violating DUI laws. This carries penalties such as a jail sentence and a permanent criminal record. In most felony charges, a DUI attorney will attempt to reduce the charges to a misdemeanor.
A misdemeanor DUI is less serious than a felony. Generally a first, second, and third DUI offense are treated as misdemeanors. Penalties for a misdemeanor are based on the severity of the charges. Usually, the penalties include a minimum jail time and fines, however, in some cases there may be additional charges like carrying a criminal record. A DUI infraction is the lightest DUI offense which is when the suspect is under 21 and has a BAC under a .05. There are different charges for a BAC .05 and BACs between .05 and .07.
