It's my opinion and knowledge that, use of emergency lighting is generally dictated by state law, not by the wording of any motor club. There are states that require emergency lights to be "on" while in-tow. Additionally, if a loaded wrecker or carrier is travelling on a highway or roadway slower than the posted speed limit for safety reasons (wrecked, over-width, over-height, permit load, etc.) state law may require that emergency lights are on. Unless local law enforcement enforces improper lighting violations, there's not much that can be done. Perhaps there's an issue of training from a reliable source, or, for towers to attend a Traffic Incident Management course to identify what's proper for the state of operation? There's a reality in this industry that suggests towers will oftentimes operate their own way as they see fit, but that doesn't make them an idiot, only incorrect as we all aren't perfect nor do we work in a perfect world.
