So, a DUI is the most serious charge for driving under the influence of alcohol. It carries a year in jail. It carries 12 points and a maximum fine of $1000.00. A DWI is driving while impaired by alcohol, which is a lesser degree and carries a maximum of only 60 days, $500.00 fine, and 8 points. So, in the most literal sense, a DUI is a lesser included or lower form of driving impaired by alcohol.
