When is a driver required to undergo a written exam during renewal?

A driver is required to undergo a written exam during renewal only if their driver's license has been expired for more than one year. This is designed to ensure that drivers who have not been on the road for an extended period, typically over one year, are still familiar with the rules of the road and safe driving practices. The need for a written test in this situation addresses potential gaps in knowledge that may have occurred during the lapse in licensure.

When a license has been expired beyond this timeframe, it is necessary to assess the driver's understanding of current traffic laws and safe driving procedures, which may have changed since their last renewal. This requirement helps to promote road safety and ensure that all drivers on the road are adequately informed and competent.

In other situations, such as if the license is expired for less than one year or the driver is under 21 years old, there might not be a requirement for a written test. Similarly, if the examiner does not request a written test, the driver may be able to renew their license without this added step.
