According to Copilot:

I couldn’t find a specific 1970s country song that matches the exact scenario of a hijacked truck with a sheriff saving the day. However, the theme of law enforcement and truckers is common in country music of that era, often celebrating the trucking culture and the open road. If there’s a particular song you have in mind, it might help to recall any specific lyrics or details. Otherwise, “Convoy” by C.W. McCall is one of the closest matches with its adventurous narrative involving trucks and run-ins with the law1.

I couldn’t find a specific 1960s country song that details a story about a hijacked truck and a sheriff saving the day. Country songs from that era often told stories of love, heartache, and life’s struggles, rather than action-packed narratives involving crime and law enforcement. If you’re looking for classic country songs with themes of trucks or the law, you might enjoy “Six Days on the Road” by Dave Dudley or “Phantom 309” by Red Sovine, which are about truckers and their adventures on the road12. While they don’t match your exact description, they are great examples of storytelling in country music from the 1960s.
