Speed Limiters in the USA
The US Department of Transportation has identified that it may mandate speed limiters (speed governor) on trucks weighing more than 26,000 lbs on roads with a speed limit of 55 mph or more. This mandate could be put in place as soon as October 2015, but the specifics have not yet been released, including the max speed trucks would be allowed to travel. Previous proposals had stated the the maximum speed might be set at 68 mph.
In Ontario and Quebec, speed limiters are set for 105 km/h (roughly 65 mph) where the typical speed limit is 100 km/h.
- Speed limiter: Requirements will apply to vehicles that were manufactured in 1995 or newer with a manufacturer’s gross vehicle weight rating (MGVWR) of 11,794 kilograms (26,000 lbs.) or more. Only commercial motor vehicles with an electronically controlled engine are subject to these regulatory requirements. (MTO 09/27/2013)
