How to handle speed bumps

The “wide bumps” that you refer to are technically called speed humps. When properly installed, they have a very gradual ramp-up and down cross section that causes very little jolting and at their designed speed, will allow the car to roll smoothly across, even at 15-20 mph. They operate on the principle of allowing enough time (e.g., slower speed) for the fluid in the shocks to bleed through the orifice without causing the jolt when the shock is required to expand or retract at too fast a rate. Unfortunately, not many highway/street contractors know how to properly install them. I’ve seen what should have been humps that were built wrong, and merely function like 5-foot wide speed bump.
