If its expired you can not legally drive. However You can renew 11 months b4 or 2 yrs after if your not driving. You don't have to go thru the whole process unless it's over 2 yrs expired. U can renew online if you get an eye test done at a pharmacy. However you won't be able to print out a temporary license to carry with you over until the new license arrives in the mail.
When you license is near expiration, you need to submit a form for renewal 4-6 weeks in advance (submit renew form 2 months from expiration)
Before. Once it expire you gonna be in trouble if you intend to drive. Also might have to go though the whole process.
