Are you under 21 and trying to get a critical need license or are you trying to get a restricted license earlier than you would typically be allowed to. If you are under 21, get an attorney to assist you. These are almost impossible to get on your own. If you want to try on your own try contacting your local DMV Driver Safety Office. You can find their number of the DMV website.
Thank you for your question. The generic answer is the phone number is (916) 657-6525. However, you may find that sending a fax to them asking you to call ends up in less time waiting, or the old trick of calling another Sacramento DMV number, and asking to be transferred in internally works like a charm. I hope that this helps, but if you have any other questions, please feel free to ask anytime. All the best to you.
