If your a cdl driver when you park your car at the company you need to be back in that car 14 hours later and once a week it can be 16 hours later when you start doing dock work your still a driver your job title did not change
Not exactly correct. Yes, you may be a driver but as long as you log your work time correctly (driving, on duty-not driving, etc.) you can work as many non-driving hours as you like. HOS regulations only specify when you can or cannot DRIVE. You can complete 14 hours of driving/non-driving work and then still work the dock for as many hours as you like for instance. You just cannot DRIVE again till you meet the rest requirements (10 consecutive hours off duty) in addition to not exceeding the 70/8 or 60/7 limitations.
