Bumper stickers are often used on commercial vehicles so that employers can receive feedback about the driving habits of their employees.

A bumper sticker is an adhesive label or sticker with a message, intended to be attached to the bumper of an automobile and to be read by the occupants of other vehicles - although they are often stuck onto other objects. Most bumper stickers are about 8 cm by 30 cm (3 in by 12 in) and are often made of PVC.

Here are some funny bumper messages:

He who laughs last thinks slowest!

A flashlight is a case for holding dead batteries.

Lottery: A tax on people who are bad at math.
