The only way im stopping on the shoulder of a highway,is if the truck completely stops..Read too many stories like this with bad endings.I was driving across I-80 in Ohio behind another driver with the company I worked for.He informed me he was gonna stop and kick a tire.I thought he was talking about the next plaza but he just pulls to the shoulder.He was a 20 yr driver.I told him I would meet him at the next plaza because I wasnt pulling on the shoulder.
You can legally drive with a flat tire to a safe haven. Unless of course you have super singles. "The Berm" is not a safe haven.
