What Signage and Speed Limits Should Be Used with JSP Speed Bumps?

Guidance on correct signage and appropriate speeds for using JSP speed bumps effectively and safely.

When installing JSP speed bumps, it is essential to display clear and appropriate signage to inform drivers of the required speed limit. It is the responsibility of the Landowner or Leaseholder to ensure that this signage is in place.

The type of speed bump in use will determine the suitable speed limit:

50mm Jumbo Ramps
Designed to reduce vehicle speeds to a maximum of 10mph.
Suitable for areas such as:

  • Reception car parks
  • Schools and colleges
  • Hospitals
  • General workplace environments

75mm Jumbo Ramps
Designed to reduce vehicle speeds to a maximum of 4mph.
Best suited for:

  • Dockyards
  • Loading bays
  • Bus depots
  • Other high-traffic industrial areas

Appropriate speed signage should be positioned clearly ahead of the speed bump to give drivers adequate warning and ensure safe approach speeds. This helps to protect both pedestrians and drivers while maintaining a safe and controlled environment.

Key points:

  • Signage is the responsibility of the landowner or leaseholder.
  • 50mm ramps: max speed of 10mph – ideal for lighter-use areas.
  • 75mm ramps: max speed of 4mph – best for industrial or high-traffic zones.
  • Clear signage must be installed ahead of speed bumps.
  • Proper signage helps ensure safety for all road users.
