On the way to Chicago on U.S. 14 yesterday I passed by a sign alerting drivers to motorcycles, and I stopped on the way home to take this picture.
It's in Des Plaines (Ill.), near Des Plaines Honda, a large motorcycle dealer.
As a busy dealership, there would be many motorcyclists entering and leaving its driveway. It doesn't enjoy the setback or front driveway of Northwest Honda in Crystal Lake or of Woodstock Harley-Davidson on Route 47 in (where else?) Woodstock. Approaching drivers have a very limited view of motorcyclists trying to exit the dealership.
Three cheers, and thanks, to IDOT for installing this important warning sign.
