6. Description of  content : NHTSA and FMCSA are proposing regulations that would require 
vehicles with a gross vehicle weight rating of more than 11,793.4 kilograms (26,000 
pounds) to be equipped with a speed limiting device initially set to a speed no greater than 
a speed to be specified in a final rule and would require motor carriers operating such 
vehicles in interstate commerce to maintain functional speed limiting devices set to a 
speed no greater than a speed to be specified in the final rule for the service life of t he 
vehicle.  
Specifically, NHTSA is proposing to establish a new Federal motor vehicle safety standard 
(FMVSS) requiring that each new multipurpose passenger vehicle, truck, bus and school 
bus with a gross vehicle weight rating (GVWR) of more than 11,793.4 kilograms (26,000 
pounds) be equipped with a speed limiting device. The proposed FMVSS would also require 
each vehicle, as manufactured and sold, to have its device set to a speed not greater than 
a specified speed and to be equipped with means of reading the vehicle's current speed 
setting and the two previous speed settings (including the time and date the settings were 
changed) through its On -Board Diagnostic connection.  
FMCSA is proposing a complementary Federal motor carrier safety regulation (FMCSR) 
requiring each commercial motor vehicle (CMV) with a GVWR of more than 11,793.4 
kilograms (26,000 pounds) to be equipped with a speed limiting device meeting the 
requirements of the proposed FMVSS applicable to the vehicle at the time of manufacture, 
includ ing the requirement that the device be set to a speed not greater than a specified 
speed. Motor carriers operating such vehicles in interstate commerce would be required to 
maintain the speed limiting devices for the service life of the vehicle.  
Based on t he agencies' review of the available data, limiting the speed of these heavy 
vehicles would reduce the severity of crashes involving these vehicles and reduce the 
resulting fatalities and injuries. We expect that, as a result of this joint rulemaking, 
virtually all of these vehicles would be limited to that speed.  G/TBT/N/USA/1188
