In California a restricted license granted after a second DUI conviction has guidelines that need to be followed. According to CA law the restriction of the driving privilege shall be limited to the hours necessary for driving to and from the person’s place of employment, driving during the course of employment, and driving to and from activities required in the driving-under-the-influence program.
Section 13360 of the California vehicle code states that upon receiving satisfactory evidence of any violation of the restrictions of a driver's license, the CA department of motor vehicles may suspend or revoke the license.
So if you are caught driving outside your restrictions it appears that your driving privileges would be once again taken away. The California DMV should be able to advise you if there will be additional penalties given to you by the courts if you are pulled over and cannot prove you are driving within your restrictions.
