Back in 1991, the U.S. Department of Transportation announced that it was going to rewrite and simplify its motor carrier safety regulations. The "zero-base review," as it was called, which was to have been completed by 1994, is now at the White House Office of Management and Budget for review.

The revised regulations have not been rewritten from "Zero" (start all over) as originally stated, but rather edited and reorganized by subject matter and presented in a question-and-answer format.
According to the National Private Truck Council's Director of Safety Programs, the revised rules should be announced in the federal rulemaking process with the usual 30-day comment period. He speculated that it wouldn't make sense for DOT to move forward with its proposed changes in drivers hours of service rules if the changes in the existing rules aren't released.
