Toward the end of the summer, the U.S. Department of Transportation (DOT) announced that the National Highway Traffic Safety Administration (NHTSA) and the Federal Motor Carrier Safety Administration (FMCSA) together were proposing to equip "heavy-duty vehicles with devices that limit their speeds on U.S. roadways, and requiring those devices to be set to a maximum speed," according to a news release from the FMCSA. The speed limiters, the agencies believe, could have the ability to prevent deadly trucking accidents in addition to saving more than $1 billion in the cost of fuel due to lower traveling speeds.
According to U.S. Transportation Secretary Anthony Foxx, "in addition to saving lives, the projected fuel and emissions savings make this proposal a win for safety, energy conservation, and our environment." Can the requirement of speed limiters truly make the difference?
Safety Standards Under the Proposed Rules
Under the proposed rules, "all newly manufactured U.S. trucks, buses, and multipurpose passenger vehicles with a gross vehicle weight rating more than 26,000 pounds" would have to "come equipped with speed limiting devices." Would all vehicles have the same speed limits? In its current incarnation, the agencies have proposed three different maximum speed levels of 60 miles per hour, 65 miles per hour, and 68 miles per hour—the vehicle's speed limiter could be set accordingly. At the same time, the agencies have indicated that they are open to public input concerning the maximum speeds permitted by the devices.
