First DWI Administrative Consequences

You will also have to pay a reinstatement fee of $45.00 plus maintain SR-22 Insurance for a period of two years from the date of your suspension/revocation. Additionally, you may have to install an ignition interlock device to regain limited driving.
Courts also commonly impose conditions like no alcohol violations, community service, and regular check-ins with a probation officer. While some people avoid conviction and jail through probation, the charge is serious. It creates a record of DWI conviction which can be used to enhance the charge of any future DWIs. It can also affect employment opportunities, relationships, and insurance premiums. Putting forth a strong DWI defense can often reduce the impact of a first DWI.
