In Ontario, the car license process has three levels: G1, G2, and G. A G1 license comes with restrictions for new drivers, with a view to fostering safe driving habits. Drivers with these licenses must be with a G-licensed driver in the passenger seat. G1 drivers cannot ride on expressways, or between midnight and five in the morning.  G2 is the next step up, letting drivers practice with the license for a year without requiring another driver in the vehicle. There are additional restrictions for G2 license holders under the age of 19. The final step is the G license, one free of caveats.
