In Canada, the Truck Rental and Leasing Association is asking the Ontario provincial government to exempt its members from having to put speed limiters on their existing fleets. Instead, the association is asking that any limiter law be applied only to new trucks that are not yet in service.
The Canadian online publication Today’s Trucking reported that TRALA is also opposing proposed New Jersey legislation that would mandate speed limiting devices on any commercial truck operating in that state.
Trucks that were built to reach their so-called “sweet spot” at 70 miles an hour, for example, lose performance if held to 65. Trying to compensate by downshifting hurts fuel economy.
