MILWAUKEE— Truck drivers continue traveling across the country as essential employees.

They're keeping supply chains in motion, but they're also busy delivering key items that will help the nation combat the coronavirus such as PPE supplies and the vaccine. 

"We are in this job to help get everyone their shipping needs taken care of," says Carl Marks, a Wisconsin truck driver. "So to be out there to deliver the vaccine is a good feeling."

And while Marks is helping others, he's asking Wisconsinites to help him, too.

Marks asked people to keep their distance when traveling on the roads and not cut them off so that everyone can get to their destinations and safe home to their families.
