What is Governed Speed

In trucking the term governed speed refers to the maximum speed at which a commercial motor vehicle is electronically limited to travel. This speed limitation is set by the truck’s engine control module (ECM) or electronic control unit (ECU) to ensure safety, fuel efficiency, and compliance with regulations.

Why is the Speed Governed in Trucks

Governing the speed of trucks serves several purposes:

  1. Safety: Limiting a truck’s speed can contribute to safer driving conditions, reduce the risk of accidents, and minimize the severity of potential collisions.

  2. Fuel Efficiency: Trucks are generally more fuel-efficient when operating at moderate speeds. By capping the speed, carriers can optimize fuel consumption and reduce operational costs.

  3. Driver Behavior: Speed governance can encourage drivers to adhere to posted speed limits, promoting safer driving habits and reducing the likelihood of traffic violations.

Who Sets The Governed Speed Limit

The governed speed limit can vary based on the carrier’s policies, the type of road (urban vs. highway), and regulations. In the United States, there isn’t a federal mandate that specifies a standard governed speed for all trucks. However, many carriers opt for speed limits of around 68-70 mph for their trucks. Some states may have different maximum speed limits for trucks, which can also influence the governed speed setting.
