No. You can use 1 extra hour driving in adverse weather unknown to you at departure, but not to exceed 14 hrs total time. If you have already used 2 1/2 hrs of on duty not driving time, then you only get an extra 30 min of driving. Using personal conveyance to come in on is definitely not lawful. And yes they can find out if you were legally under an adverse weather exemption by a lawyer at $350.00/ hr if there are a couple of million dollars on the line. Believe me, It is an easy 33% of 2 million dollars. Even if the accident is not your fault, you will still be guilty under the law for violating your hrs of service. Screw the dispatcher and terminal mgr. Call your safety dept and ask to talk to the dir of safety himself and ask him if he really wants you to place your company under that sort of indefensible liability because they don't want to come out and pick you up. Even at midnight, the GO has a safety supervisor on standby for calls like this. And then just sit back and smile and wait for the phone call.... They will be pissed for a while, but they will get over it. BECAUSE THEY KNOW YOU ARE RIGHT, AND THEY WILL GRUDGINGLY RESPECT YOU FOR IT. OR you can keep playing the percentages and risk it on a roll of the dice each time. After all, you are only hanging your a$$ in the wind for the length of time you are willfully in violation of DOT rules. Sure you are a good enough driver to risk it, but what about that teenager that was texting when he crossed over into you? Or spun around in front of you? Or.....? BTW I am not referring to you specifically DD, but only in a general sense to every driver who may need assurance of what to do.I've been under the impression that the weather exemption was history when the driving shift was changed from 10 hours to the present 11 hours in 2003.
