Rule for heavy vehicle speed limiters should apply to EXISTING large trucks

In your message – insert a personal account or interest in the speed limiting rule, and ask your members of Congress to insist US DOT issues a final rule PROMPTLY that includes ALL existing large trucks. 

  • As the agencies noted in the proposal itself, speed limiting devices have been built into most big rigs since the 1990s, thus there is no capital expense required to include them.
  • I am extremely disappointed that the proposed rule would only apply to new large trucks.
  • There is no good reason to limit this to new trucks, which would greatly reduce and delay the safety benefits to all US motorists.
  • A recent report from Ontario states that big-rig fatal crashes reduced 24 percent after they began requiring settings of 65mph.
  • The National Highway and Traffic Safety Administration (NHTSA) data shows that trucking is getting less safe:
    • Crashes involving them have increased by 44% between 2009 and 2014.
    • Injuries resulting from truck crashes have skyrocketed 50% between 2009 and 2014.
    • Fatalities have increased again as well: Newly released data on 2015 truck crash fatalities show a 20% increase from 2009 to 2015.
  • A Federal Motor Carrier Safety Administration (FMCSA) study concluded that trucks not using speed governors were in twice as many high-speed collisions as those using them.
  • An FMCSA report found that 40.3 percent of all fatal crashes involving large trucks in 2014 were at speeds of 60 mph or higher.
  • Not utilizing existing technology that has been proven to save lives, would be like having a new seat-belt rule stating they should only be worn in future vehicles.
  • The United States is the only leading country without such a rule.
  • The European Union countries, Japan, Australia and the most populous Canadian provinces (Ontario and Quebec) all require speed governors to be set on heavy commercial vehicles at speeds varying from 55 mph in Japan to 65 mph in Canada.

Conclusion:

Option 1:

While I support speed-limiting technology, the rule must mandate this life-saving technology be used on all big rigs that already have the capability built in, as well as new trucks.

Option 2:

Failure to ensure that this regulation applies to existing trucks that are already equipped with a speed limiting device, will result in a regulation that appears to promote safety, but will in fact do very little to improve it for many years to come.

The term “tractor-trailer” or "big-rig" used on this website
refers to all Class 8 trucks which is the heaviest class.
