Cars, trucks and motorcycles need to get along. Cooperation both ways would make life a lot safer for everyone. These roadside ads are excellent. I wish we had similar ads here in Ontario, Canada. They are a two part ad campaign, one part directed at drivers and the other at motorcycle riders. Kudos to the great State of Utah.
Here are a couple directed at drivers:
Utah Department of Public Safety: Bikers make Lousy Speed Bumps
Utah Department of Public Safety: Cars have Bumpers, Bikers have Bones
Here are a couple directed at motorcycle riders:
Utah Department of Public Safety: Road Rash is Preventable
Utah Department of Public Safety: To Cars and Trucks You're the Bug
Utah Department of Public Safety: It's Born to be Wild, not Crazy
