There are various types of charges with various penalties. If you are found guilty of DUI, DUI Per Se, or DWI by Controlled Dangerous Substance, you could receive 12 points on your license and a maximum penalty of 1 year in jail and a $1,000 fine for a first offense, 2 years and $2,000 for a second offense, and 3 years and $3,000 for a third offense.
If found guilty of DWI by Alcohol or DWI by Alcohol and Drugs, you are more likely to receive 8 points on your license and a maximum penalty of 60 days in jail for a first offense and 1 year for any subsequent offense. As you can see, your penalties will come down to which precise charges you have, your history, and whether or not the judge assigns you the maximum penalty.
