Difference between Speed Humps and Speed Bumps

Debbie Moore | November 2, 2011

Just like the names, it can be very confusing to figure out the difference between speed humps and speed bumps on the roads. The most commonly known fact is that they both help slow down the vehicle and control speed. While driving on the road, people are usually unsure of what exactly these obstructions are and what they are there for. They both control the traffic but the major difference lies in the amount of traffic they can control. Due to the distinction in design and size, there are considerable demarcations between them.

Significant differences between Speed Bump and Speed Hump:

Speed Hump	Speed Bump
Speed Humps are lower and are placed at a longer driving distance.	Speed Bumps are lower and are placed at a longer driving distance.
They are less aggressive in controlling traffic as they are lower.	They are more aggressive in controlling traffic due to the size.
Speed humps control traffic to around 25 – 30 mph.	Speed bumps control traffic to around 0 – 5 mph.
They are narrower than speed bumps.	They are wide as compared to speed humps.
Travel length is about 12 to 15 feet.	Travel length ranges from 6 inches to 3 feet.
Height is typically 3 to 4 inches.	Height normally ranges between 3 to 6 inches.
Speed humps offer softer intrusion. Traffic normally remains moving but at around 10 -15 mph.	Traffic proceeds slowly in areas where speed bumps are placed.
They are better suited for high traffic areas, entrances from major highways and areas with larger vehicles.	They are typically intended for front of store or school entrances, parking lots, at pedestrian crossings, garages and near stop sign locations.

Speed bump and speed hump, both are designed to address the ongoing problem of speeding. Both are usually made of rubber tires and constructed with a reflective tape to ensure maximum visibility. Installing these traffic control devices is a great way to reduce injuries. Many drivers will travel past and ignore the painted lines on surfaces and also the stop signs but these speed bumps and speed humps cannot be ignored by speeding drivers. These tactical insertions on the road promote awareness and make drivers sensitive to speeding consequences.
