wanted to update, since I got a message over the qualcomm a few nights before New Years Eve.
The message instructed ALL Werner company drivers (O/O's were exempt) regardless of department, account or division to shut down no later than 10 pm on New Year's Eve and to remain parked until 6 or 7 am in whatever time zone you were in. The only way you could drive is if you were on an urgent high value load. That was the only exception.
aside from that, as far as I know most people drove Thanksgiving and Xmas, especially those in mid-route. Those empty and needing a load, probably did sit due to most places being closed.
