If you are 21 years or older, learner’s permits are non-renewable. If an existing learner’s permit is expired, you must re-take the knowledge test to obtain a new learner’s permit.

Learner’s permits are valid for one (1) year.

GRAD Only (age 16-20 years)
If your learner's permit expires before you are able to move to the next stage (provisional driver's license, if under age 21), you may renew your learner's permit within 90 days of expiration to avoid taking knowledge test again.
