I am teaching my husband to drive. It's not going well. I was afraid that someone would call the police with reference to the "drunk", "unbalanced", "disabled" or "child". So I bought these magnets to alert other drivers and pedestrians to a real problem while driving. They're bright, easy to read, and come in packs of 3 so all corners are covered (maybe I need a big mirrored one for the hood). too?), and they're easy to put on and take off after class. They feel solid and should last for years to come until they pass the road test.
