The Motor Vehicle Department Database
The Motor Vehicle Branch administers driving tests and issues driver's licenses.
Any person who wants a driver's license must take a learner's exam at any Motor
Vehicle Branch in the province.
If he/she fails the exam, he can take the exam again any time after a week of the
failed exam date, at any branch.
If he passes the exam, he is issued a license (type = learner's) with a unique
license number.
A learner's license may contain a single restriction on it. The person may take
his driver's exam at any branch any time before the learner's license expiry
date (which is usually set at six months after the license issue date).
If he passes the exam, the branch issues him a driver's license.
A driver's license must also record if the driver has completed driver's education, for
insurance purposes.
