Key Differences

When to Choose a Speed Bump vs. a Speed Hump

Speed Bump

• Crosswalks and entrances to schools, churches, or businesses
• Parking lots or private roads where vehicles need to slow down to below 10 mph
• Areas with a high risk of pedestrian activity

Speed Hump

• Residential neighborhoods where a smoother flow is preferred
• Parking lots with lighter traffic
• Areas that benefit from maintaining speeds between 10–20 mph

Pavement and Installation Considerations

• Pavement Condition: On flat surfaces, longer speed bumps can cover multiple lanes. On crowned or uneven pavement, shorter, end-to-end installations help maintain functionality.
• Material Options:
  • Recycled Plastic: Resembles traditional concrete, often dyed bright yellow for high visibility.
  • Recycled Rubber: Features a black-and-yellow design with embedded yellow stripes, ideal for uneven surfaces.
• Anchoring Methods:
  • Concrete: Use lag bolts with expanding anchors or self-tapping concrete screws (with masonry drilling).
  • Gravel/Dirt: Spikes are generally the only viable option.
  • Asphalt: Expanding anchors work best on older, hardened asphalt; avoid self-tapping screws.

Additional Features

• Reflective Elements: While standard yellow plastic bumps work well in daylight, adding reflective yellow tape improves nighttime visibility.
• End Caps: End caps offer a neat finish and protect the edges from wear, although they are not essential for functionality.
