To set different forklift speed limits by zone, map the areas with different risk, such as docks, pedestrian crossings, narrow aisles and production entrances, assign each a maximum speed, and enforce it with technology rather than signs alone. Enforcement uses a geofence or zone marker that the truck recognises on entry, plus a speed-control interface that limits travel speed on compatible forklifts, meaning those with CAN-bus access or a speed-limiting kit. On trucks without that interface, the zone can only warn the operator. Record each zone and its limit in the written traffic management plan.
The full guide is Zone-based forklift speed control. OSHA 1910.178 requires operators to travel at a speed that allows a safe stop and to slow down at cross aisles and where vision is obstructed, but it sets no figure; the limit for each zone is the employer’s decision, based on the risk assessment.
Check how each zone is detected (UWB anchors, magnetic or RFID floor markers, camera geofences), whether slowdown is gradual, how operators see the active limit, and how overrides are logged. Forklift speed limiters covers the hardware on the truck.
