What age must a driver reach to transition to the unrestricted driving phase in the GDL program?

To transition to the unrestricted driving phase in the Graduated Driver License (GDL) program in Texas, a driver must reach the age of 18 years old. This phase is designed to allow young drivers to gain experience while gradually increasing their driving privileges.

At the age of 18, individuals have typically completed the necessary requirements of holding a provisional license for a minimum period, which includes meeting specific practice driving hours and having no serious traffic violations. This age is crucial as it's when individuals are recognized as legally adults in many contexts, including the ability to freely engage in driving without further restrictions that apply to younger drivers.

The earlier ages listed do not suffice because the GDL program emphasizes safety and experience over the mere age of the driver. Thus, only at 18 can individuals enjoy full driving privileges without the limitations imposed on younger, less experienced drivers.
