The American Trucking Associations has petitioned the National Highway Traffic Safety Administration to limit the maximum speed of large trucks at the time of manufacture to no more than 68 miles per hour. ATA also petitioned the Federal Motor Carrier Safety Administration to prohibit the tampering or adjustment of the speed limiting devices, known as speed limiters (or governors), to greater than 68 miles per hour.
Research indicates that speed is a more significant factor in crashes involving trucks than any other factor that currently receives a larger proportion of government attention and resources.
Here is a copy of the Rulemaking Petition.
