Final answer:
A permit driver over the age of 21 usually has no restrictions on their driving, unlike younger permit drivers who have certain limitations.
Step-by-step explanation:
A permit driver over the age of 21 usually has no restrictions on their driving. Unlike permit drivers under 21, who typically have restrictions on driving during certain hours, carrying passengers and driving on highways those over 21 are generally exempt from these restrictions.
This is because older permit drivers are considered to have more experience and maturity therefore not requiring the same level of restrictions as younger drivers.
