Explanation

If a California driver under the age of 21 is found to have a BAC of 0.05% or higher in a preliminary chemical test, he or she may be required to submit to a second test. If the second test also reveals a BAC of 0.05% or higher, the driver will be arrested for DUI and his or her license will be suspended.
