For obvious reasons, transportation officials, safety regulators, truck fleet principals and passenger-vehicle drivers and their passengers all pay close attention to matters of material importance in the nation’s commercial trucking industry.

Speed would certainly qualify as one such matter, and that topic is in fact front and center in recent media reports discussing what one online publication terms “two looming trucking regulations.”

It might strike some readers as ironical that the process leading toward the passage of a final safety rule from the U.S. Department of Transportation has been anything but speedy.

In fact, the long-ago proposal that the nation’s large trucks be uniformly outfitted with speed limiters seems to still be in limbo, with the projected date for final clearance and publication being recently delayed following earlier postponements. The above-cited media story notes that the currently proposed rule “has been stuck [in a relevant White House office] since May 2015.”

Another proposed regulation relating to drivers’ alcohol and drug use has also been delayed. That rule calls for a national database of commercial drivers who have either refused to take a drug test or failed one.

The speed-limiting debate has been protracted and vigorous, with strongly competing views on both sides of the issue.

Proponents of the proposed rule routinely laud the idea of a maximum controlled speed for large rigs on grounds of enhanced roadway safety.

Some critics, conversely, have passionately derided it, saying that it will contribute to roadway congestion and other problems that will simply increase — rather than mitigate — traffic risks.
