Driving the bus last week. A warning sign on the back of a construction looking semi-truck on the highway in the next lane. Cloth cover pulled over the load. Not a very big sign, but black and orange so we know it’s a warning of some sort. Pull the motorhome a little closer. Can’t read it. Closer. Almost. At maybe two car lengths away I can just make it out to read it. It says “Stay back 300 feet! Not responsible for broken windshields.” I’ve seen that sign before! We have a big windshield in the motorhome. We got it way away from that truck in a hurry,
