The invention provides for a governor (10) for a motor vehicle engine. The governor (10) includes a series of strain gauges (14) for measuring changes in the load of a motor vehicle (12) and a microprocessor controlled printed-circuit board (PCB) (22) for computing a predetermined maximum velocity for the vehicle based on the vehicle load. The PCB is electronically linked to the strain gauges (14) via an amplifier (18) and an analogue/digital converter (20), and is arranged to control rotation generated by the engine via an engine management system (13) so as to prevent the engine from powering the vehicle to an actual velocity greater than the predetermined maximum velocity.
