The American Trucking Association and Road Safe America have petitioned
to establish a safety standard to require Engine Control Module Speed
Limiter Devices to be placed on certain heavy trucks. The National
Highway Traffic Safety Administration plans to initiate the rulemaking
process on this issue with a Notice of Proposed Rulemaking in 2012.
Items specific to NHTSA’s rulemaking process include the following:
1. All newly manufactured trucks with a GVWR greater than 26,000
pounds shall be equipped with an electronic control module (ECM) that is
capable of limiting the maximum speed of the vehicle.
2. The ECM shall be set at no more than 68 mph by the manufacturer.
3. The ECM should be tamper-resistant, and should be designed in a
way that does not allow the speed limiter setting on the ECM to be
adjusted to let the vehicle exceed 68 mph.
