A felony is a much more serious violation of the law. These transgressions often come with a jail sentence and a hefty fine. People who are accused of felonies tend to have to put up thousands or tens of thousands of dollars in order to fight the charge and possibly avoid it. DUIs can only lead to these charges in a rare handful of instances. There are DUIs that cause severe damage or injuries that can be pursued as felonies. There are also situations where a person is accused of their fifth or sixth DUI. They have put the public at risk for far too many times and must be dealt with.
