Norman Glover, a former truck driver and now a manager with a retail grocery chain fleet, said the current HOS rules need to be updated to give drivers more flexibility so they can better manage their work time around traffic and weather conditions. "Do we want a driver to expose himself and his rig to rush hour traffic? Or be able to take a break and let it subside?" he said. "At the end of the day, the less traffic they encounter, the less potential there is for an accident."
