Bring attention and slow vehicle traffic down using the Speed Nub Safety Bump Rumblestrips. Made from rubber (yellow sections and recycled rubber (black section), this speed bump rumble strip is designed with a low profile (1/2" height) to prevent vehicle damaged while the black and yellow color combination displays a traditional caution notification. Preferred for low speed environments such as schools, shopping centers, business and private parking lots, Speed Nub Safety Bumps can add rows of bumps to match the level of caution that drivers need around certain areas.
