It really depends upon the county in which this occurred. He is fortunate both of the charges are misdemeanors. Some counties grant Suspended Imposition of Sentences (SIS), while some don't, only granting Suspended Execution of Sentences (SES). It is important for him to hire an attorney within 15 days of the date of the arrest, otherwise, his license will be suspended without getting a challenge. The Leaving the Scene of an Accident charge is the more serious offense, as not only is it a Class A Misdemeanor (the DWI is a Class B), but it also carries a one year loss of driving privileges with no chance for a hardship.
