I'm a cover driver, not working more than a couple days a week right now. I recently started a janitor job at my wife's work. I'm trying to understand the DOT 10 hours off rule a little better. If I clean from 6 AM to 8:30 AM, am I not allowed to hop on a truck and drive starting at 9:15 AM due to the 10 hours off rule? Does this rule only apply to driving jobs, or do I need 10 hours off from cleaning before I can drive?
