Description
The two new speedbumps need to be painted. Despite signage pointing to the bumps, they are barely visible until drivers are upon them. This is a danger to the drivers and their cars. It's great that this traffic-calming measure is in place, but PLEASE PAINT THE BUMPS. Thanks.

Speed humps, which are different than speed bumps, are considered a traffic calming device, not a traffic control device, and there are no federal regulations governing the humps themselves. The United States Department of Transportation's (DOT) Federal Highway Administration (FHA) has standards regarding signage and roadway markings and makes recommendations about what signs and markings should be used for speed humps.
Difference Between Humps and Bumps
Speed humps are gently raised strips on the roadway that encourage you to reduce your speed. Humps are used on the road where vehicles are traveling above 20 miles per hour (mph) and encourage you to reduce your speed to 15 to 20 mph. Speed bumps are more severely raised strips. Bumps are usually used in parking lots where you are traveling less than 15 mph. You may need to slow to 5 mph to safely navigate the bump. Using a speed bump where speed limits are over 20 mph would cause damage to the vehicles traveling on the roadway.
Design
The FHA recommends the best speed hump design is one that gradually slopes. A 12-foot-wide speed hump that slopes gradually enough to make a four-inch change in vertical elevation is enough to reduce potential vehicle damage and reduce the amount of jarring experienced by the driver and passengers while still encouraging you to slow down. Speed humps should not be installed in the path of pedestrian crossings or curb ramps.
Signage and Markings
A speed hump warning sign should be 30-by-30 inches for a single-lane roadway or 36-by-36 inches for a multi-lane roadway. The minimum size sign is 24-by-24 inches and the maximum size is 48-by-48 inches. The speed hump sign should be accompanied by an advisory speed plaque to notify you of the suggested speed for traversing the hump.
Speed hump markings, if used on the roadway, must be white and placed on the hump to enhance its visibility. The markings should be 12 inches wide and form an arrow in the direction of travel.
Markings leading up to the hump should be a series of 12-inch-wide, transverse lines that become longer and are placed closer together as they get closer to the hump.

I agree please paint the humps! this one got me the other day, it was dark and cloudy and all I saw was what looked like fresh tar on the road. I missed the sogn and didn't slow down in time and bam, I only hit it doing 30, but my little bouncy SUV sent me flying. Felt like the front tires came off the ground. I heard the slap of the shocks fuilly extending.
Somebody on a motorcycle is going to get hurt from this thing. I'm not opposed to the hump itself. In fact I wish they would put a speed hump at every stop sign in the Morris cove area, because so many of YOU seem to think stopping is optional. I'm at the corner of Dean and Parker been there for 8 years and I can tell you that 90% of the vehicles do not completely stop and only about 70% of the vehicles slow down at all. All age groups too, not just kids! The only downside I can think of would be for the emergency vehicles.
Then there are the almost nightly drag races at my corner, but that's another issue all together.
