Biden was visiting a Mack Truck facility in Pennsylvania when he made the allegation to have driven the massive trucks before, which demand a specific kind of license.
"I used to drive an 18-wheeler, man," Biden announced on Wednesday in a video posted to Twitter. "I got to."
There is insufficient proof that Biden has ever driven an 18-wheeler truck.

When questioned if the president had ever driven such a truck, a White House spokesperson pointed to a December 1973 article from the Wilmington Evening Journal that showed Biden rode in an 18-wheeler on a 536-mile haul to Ohio.
Fox News pressed the spokesperson regarding the president’s claim – stressing that riding in a truck is not the same as driving one – at which point the president's spokesperson pointed to a United Federation of Teachers post that touched on Biden driving a school bus in the past as a summer job.

Biden met local members of the United Auto Workers Union (UAW), which represents 85% of the 2,500 workers at Mack Trucks' Lehigh Valley plant, and got a briefing on the new electric-powered garbage truck the company is piloting in New York City and North Carolina.
Later, he doffed his suit coat, rolled up his shirtsleeves, and spoke to a crowd with a backdrop of trucks parked behind him.
Biden announced "buy American" in recent years has become a "hollow promise," an apparent reference to buy American policies promoted by his predecessor, Republican President Donald Trump.
"My administration is going to make Buy American a reality," he stated.
The Democratic president had signed an executive order throughout his first week in office in January directed at harnessing the vast buying power of the federal government - the world's greatest single buyer of consumer goods - to bolster U.S. manufacturing.
