Do you need a driver's permit if you are over 18?

In the United States of America, the United Kingdom and Canada, a driver's permit is required of all drivers, regardless of age. The minimum age requirement and procedure for obtaining a driver's permit varies from state to state and country to country.

In the USA, the minimum age requirement varies from 16 to 18, depending on the state says DMV.org. The minimum age requirement in Canada varies from 14 to 18, depending on the province or territory as stated by Service Canada. In the UK, residents can obtain a driver's license once they reach 17 years of age according to GOV.UK. It is best to check the official governmental website of the state/province/territory in which one resides to determine the appropriate tests necessary to acquire a driver's permit. In most cases, a would-be driver must first acquire a learner's permit before he can apply for a full driver's license.
