The trucking industry has been a major driver of job growth in the U.S. since the 1980s.
But the number of people employed in the industry fell during the recession, according to a new report from the American Trucking Associations (ATA).
The industry employs nearly 17 million people in the United States.
But it lost 4.2 million jobs between 2013 and 2016, the association found.
The association, which has been lobbying Congress to regulate the industry since the early 1990s, says it has spent $7.2 billion lobbying over the past decade.
“The decline in trucking employment in 2016 has been driven in part by the recent enactment of federal legislation that prohibits the importation of non-compliant trucks,” said David Stove, executive director of the association, in a statement.
A federal law that requires truckers to get a certificate of compliance was signed into law in December.
However, the industry says the new regulations have only resulted in more paperwork and paperwork has made it more difficult for truckers and drivers to work.
Truckers were forced to submit paperwork and fill out paperwork forms with no guarantee of compliance.
More than one-third of the truckers who were injured or killed on the job in 2016 were not properly trained and the industry blames the law for that.
Stove said the association has lobbied Congress and the U-S Customs and Border Protection to expand the requirements for trucks to include a safety and health component.
