The Dept. of Transportation asked for public input to determine the setting in the proposed heavy-duty truck speed limiter mandate—and it got it. Much of it from the trucking industry , however, is especially critical of that approach, arguing that regulations should be based on data, not opinion polls. So it should be up to the agencies in charge—the Federal Motor Carrier Safety Administration and the National Highway Traffic Safety Administration—to pick a setting and show that it will work.
While typically in favor of the 65 mph option, the fleet comments also urge the agencies to make the rule applicable to as many trucks as possible—not just to trucks built after the rule takes effect.
