Review on Zone Tech 5" X 5" Student Driver Magnet Sign - Caution Safety Warning, Please Be Patient (1) by Michael Maes

Simple to put on and take off. Strong enough to stay on so far. I drive a Chevy Traverse and it fits perfectly on the back so it is visible to other drivers. My son puts it on before driving and I take it off when we switch or get home. He appreciates the fact that it is there as he is so nervous driving for the first time. It gives me a little piece of mind too, and I think other drivers are thankful as well.
