“By and large, 99 percent of the plates out there will reflect just fine,” LaFrance said. You’d imagine that older, green-and-white plates would account for the remaining 1 percent. But not necessarily, LaFrance said.

“It kind of depends how much salt and how much sun and how old the plate is,’’ he said. “Some older folks put the car with a green plate in a garage and it never comes out, so it still reflects.”
