Provisional license.

The Provisional or Intermediate license is the central phase in a comprehensive Graduated Licensing System. Young drivers qualify for a Provisional license by completing their Learners phase, reaching a specified age, and passing a road test. Provisional license holders are allowed to drive unsupervised subject to various restrictions. Typical restrictions include prohibitions against night driving, passengers and alcohol. The goal is to limit teen exposure to risky driving situations during their first few months of licensure, a time when their crash rates are extremely high. States with such restrictions have been shown to have lower teen crash rates than states without. Parents indicate strong support both for Graduated Licensing Systems and for the specific restrictions.
