Credit card shows invalid at truck stop pumps

What's the secret to getting the pump to take my credit card. Keeps coming up invalid and I need to pay at the cashier. Thanks

Don't go to a "truck" lane.
Use one of the "car" lanes.
Assuming that your rig will fit there of course.

Almost ALL of the major stations have at least 2 diesel pumps on the "car" side these days.....if that's what you need.
