The State Matters.
The COUNTRY matters.
Canada and UK is almost a death-penalty !
I have been stopped 10+ times since 1993 for "PROBABLE CAUSE" of no plate.
Then they check my tire treads, exhaust noise, seatbelt use, and you gotta start 'splainin stuff. WHY PROVIDE PROBABLE CAUSE! The day I mouted my vanity plate INSIDE the front windshield, between glass and dash, the plate-stops ended.
ENFORCEMENT is why VCA-BC came up with the "rubber wishbone" brackets that PartsRack carries. The wishbone ends have BARBS that snap in place behind the facia crosshairs. Installs in 5 seconds. Comes off in 10 seconds. Fits US and long Euro plates.
Mount the plate to the bracket, and carry in your TRUNK. When stopped for probabe cause, you say: ""OOOPS, Sorry, we just took it off for a carwash and forgot. Ill just pop it right back on.""" Your Viper is probably spotless.....you just passed the mandatory-attitude-check. Cop stays friendly, likes the Viper. No ticket. No warning. Later, back in the trunk..... until OOOPS.... "washed the car again...."
