TAS Driver Licence Number

Detects Tasmanian driver licence numbers in the established seven-digit or one-letter-plus-five-or-six-digit shapes. Enforceable tiers require an explicit licence-number label and Tasmanian context; the strict tier additionally requires Transport Services, Service Tasmania, or Department of State Growth authority evidence.
