Driver Services: Driver Improvement Program

Drivers Age 18 and Over

If you are convicted of a demerit-point violation (or safety belt and child restraint violation) committed when you were age 18 or 19, you will be required to complete a driver improvement clinic.

If you are 18 or older and you accumulate eight demerit points in 12 months (or 12 points in 24 months), you will receive an advisory letter that cautions you about the consequences of violating the law.

If you accumulate 12 demerit points in 12 months (or 18 points in 24 months), you will be required to complete a driver improvement clinic. You must enroll in and satisfactorily complete the clinic within 90 days.

If you accumulate 18 demerit points in 12 months (or 24 points in 24 months), your driving privilege will be suspended for 90 days. Additionally, you must complete a driver improvement clinic before your privilege will be restored. Once your privilege is restored, you will be placed on a six-month probation period.

If you are under age 20, a computer-based driver improvement clinic will not satisfy a driver improvement clinic requirement. You must satisfactorily complete a clinic that provides classroom instruction
