Quebec registration plates prohibited in front   But why What bad would it do to put another plate in front I dont understand    That is a question to ask the Qubec government for their specific reasoning on that I know for a fact safety is one reason some jurisdictions give Example A front plate might look real and be confused for a real plate in other jurisdictions that have a front plate you can take your pick  im just hypothesizing why I do know that some vehicles in Qubec Semis tractor trailers are required to have a front plate as the trailer hides the plate on the back of a Truck tractor for example Like I said just because its not legal it does not mean police enforce it and just because it hasnt been enforced by some police does not mean it will not be by others
