The first trip out I found out that when the sign on the hair pins say THIS speed, they mean it. You may get away with a few miles over on the higher speed ones but the low speed ones (under 35 mph) really mean it.
That same trip we came out from under a underpass and were hit with a gust of wind that moved the whole rig sideways half way into the next lane. Luckily the LEO next to us took it in stride and moved over to the shoulder until I could fight the rig back over. After that he rode in between the gap in front of us and behind a semi that was similarly affected.
