As long as it's a road trip with aspects of a road trip, doesn't involve any copyrighted stuff, and follows the rules of the game jam, I don't see anything wrong with taking inspiration from other media as long as you're not full-on copying it.
Considering that truckers are always on the road, I would say so! As long as it includes elements of road trips as listed on the page of the game jam I don't see why not! :D
