Well msmith1199, let me introduce you to someone that has received a ticket in California for the new 55 mph speed limit while towing, namely ME.
A few weeks after the new law became effective, I was driving my Class A diesel pusher east bound on I8 between Ocotillo Wells and El Centro, towing my Hummer H3, and going 70 mph. 70 was the "old" speed limit for that stretch. Suddenly, a CHP officer was alongside me and motioning me to the side of the road. My VERY FIRST ticket for a moving violation in 50 years of driving!!
