Bump or hump; they do the same job

    Bumps and Humps may serve the same purpose, but they work differently. Bumps are just that… a BUMP. There is little choice but to slow down.

    Speed Humps, on the other hand, are designed to allow vehicles to pass at a reasonable speed — about 40-50 km/h — with just a gentle rise-fall as it crosses. Hitting the Hump at greater speed, however, causes the vehicle to bottom-out, providing a jarring impact to underscore the driver was going to fast.

    We have had two Humps installed on a recently-rebuilt street, one that drivers used to use as a short-cut around a busy traffic-light controlled intersection. Residents complained of vehicles speeding up and down their street, and the City installed the Humps.

    They work. I take my students down this street so they can experience them.

    I’ve seen a lot of humps be installed in Kingston, ON as of late. I must admit, though they are mild nuisances, they do a great job. The only time I’ve ever seen them be an issue, was seeing a lumber truck’s forklift’s steering tire bottoming out on the hump, even at a slower than posted dpeed. I ended up notifying the company aftee tgat observation, for educational purposes. It wasn’t deliberate or cause by rushing, after all.

    However, I’ve seen some speed BUMPS that are poorly designed. I’ve gone over a few that I’ve quite literally drove over in my Corolla at 1/2 a kilometer an hour, and I bottom out. Bump designers, especially those on private property, need to be careful.
