>Provisional licenses are functionally the same as a driver license, but are typically issued to new drivers under the age of 18, i.e. 14 to 17 years old. Almost all states have some form of a graduated licensing provision. The actual restrictions and the length of time a new driver must adhere to them vary widely by state.
