You can be 100% safe and legal and still be in trouble on the road. When I was first hauling heavy equipment I was humming up a long straight stretch, two lanes of traffic, no on or off ramps, 55 mph zone... left about six or eight car lengths for stopping distance, plenty! Got up to where there was a signal light ahead, light turned yellow, five cars dove over to get in front of me... not enough air on the planet to stop that rig! Luckily with all the tires howling and billowing smoke the left lane cleared and I went sliding by all those idiots who no doubt were thinking how stupid that truck driver was, hadn't I seen the light? Was only the beginning but it sure as hell made me a lot wiser driver.
