Don't you mean "Speed Bump Ahead" Correction!

After being informed that there was a difference between a 'speed bump' and a 'speed hump', I did some more research and found out that speed humps are often implemented as a 'municipal solution' where as speed bumps are used in a more residential/private area. (www.trafficlogix.com) Also, the dimension for a speed bump is around a foot wide where as the 'hump' can range from a few feet to as many as 14 feet. Very interesting. Thanks to Josh Taylor, www.makeseriously.com, for pointing this out -- now instead of cracking up in the morning, I try to guess how wide the hump is. (ha).

Don't you mean "Speed Bump Ahead"?

Every morning when I arrive at work I pass the sign that is pictured below. I never paid too much attention to the wording until the other day I realized it read "hump" instead of "bump". I'm pretty sure in Ohio they're called speed bumps so I've always read the sign as just that. Now every morning as I approach the parking lot I read the sign as more of a command: "Speed hump ahead". Cracks me up every time. Oh Indianapolis.
