Yukon License Plates
Yukon is not a member of the International Registration Plan (IRP) and thus does not issue apportioned plates. Trucks and buses based elsewhere but using Yukon roads must also register their vehicles separately in Yukon, resulting in some interesting plate observations on those vehicles. Heavy Commercial and trailer plates commonly used in these cases plus the green Public Carrier permit until the 1990s.
Many thanks and appreciation to Richard Zral and Mark Bowers of the Yukon DMV for all of the updated information!
