Depending on the type of a drivers license that you currently hold, certain California drivers license restrictions may apply to it. This particularly concerns drivers under the age of 18 who must observe all California provisional driver's license restrictions for at least 12 months or until they reach the age of 18, whatever comes first. Apart from provisional license restrictions, other California driver license restrictions may limit your ability to operate a vehicle under certain conditions. For example, a very common type of a restriction is a bioptic lens restriction that requires you to wear glasses or contact lenses while driving.
Unfortunately, we were unable to locate a list of the California driver's license restriction codes, so if you are trying to find what a specific code means, you should turn to the California Department of Motor Vehicle and they will decipher the code for you. The most common restrictions that are placed on California driver licenses are the bioptic lens and daytime driving only. These are placed onto your drivers license if you fail the vision exam at the DMV during your California drivers permit test. In order to pass the vision exam, you must have visual acuity better than 20/200 in at least one eye without the use of a bioptic telescopic lens or similar bioptic device.
Provisional license restrictions are part of the California graduated drivers license program and it's just a small portion of the measures that were devised to keep teen drivers safe during their first years of driving. Most teenagers are under the impression that once they pass the California drivers license test, they get a full driver's license and can do whatever they want on the road. This is not exactly true, the drivers license that is issued to drivers under age of 18 is marked as a provisional drivers license and it comes with the following restrictions:
These driver's license restrictions do not apply if you have a parent/legal guardian present in the vehicle.
Note how these license restrictions are different from the California permit restrictions that you had to observe while driving under the California drivers permit. The main difference is that while operating under a learner's permit, you are not allowed any unsupervised driving whatsoever, while California provisional license restrictions merely limits your ability to drive alone to when it's safe to do so.
In certain situations, the need to travel is greater than the danger this traveling may cause and the DMV recognizes this fact. That's why you are allowed to break the provisional license restrictions, provided the following conditions are met:
In all other cases, you must observe your driver's license restrictions are all times. Restrictions will be automatically lifted in 12 months or when you turn 18, whichever comes first. You do not need to exchange your drivers license at that point.
