Article 4. Probation of California Vehicle Code >> Division 6. >> Chapter 3. >> Article 4.

Whenever by any provision of this code the department has discretionary authority to suspend or revoke the privilege of a person to operate a motor vehicle, the department may in lieu of suspension or revocation place the person on probation, the terms of which may include a suspension as a condition of probation, issuing a probationary license with such reasonable terms and conditions as shall be deemed by the department to be appropriate.
The department, as a condition of probation, may require a person whose privilege to operate a motor vehicle is subject to suspension or revocation to attend, for not to exceed 24 hours, the program authorized by the provisions of Section 1659.
The department shall have authority to terminate or to modify the terms or conditions of any order of probation whenever good cause appears therefor.
The department upon receiving satisfactory evidence of a violation of any of the terms or conditions of probation imposed under this code, may withdraw the probationary license and order the suspension or revocation of the privilege to operate a motor vehicle.
Unless probation was imposed for a cause which is continuing, the probationer, after not less than one year, may request in writing the termination of the probation and the return of his regular license. Upon a showing that there has been no violation of the terms or conditions of the probation for a period of one year immediately preceding the request, the department shall terminate the probation and either restore to the person his driver's license or require an application for a new license.
