When you're dealing with mirrors, size is important. Let's say you're in a department store trying on a new pair of pants. However, the dressing room is equipped with only a handheld mirror.

Not only will towing mirrors help keep you, your cargo and people around you safe, they'll also keep you within the bounds of the law.
