Speed Limiters - Possible New Mandate for Truckers

With the CSA and the impending hours of service change, there is a new mandate on the horizon for the trucking industry. The NHTSA has begun the rulemaking procedure to make speed limiters mandatory on all heavy-duty trucks, with the set speed being 68 MPH. The move is being pushed heavily by the ATA, Road Safe America and nine major motor carriers. By governing all trucks to 68 MPH, will this improve safety or is this a way for the major carriers to level the playing field for the hiring of drivers in this new CSA environment?
