While driving on the NJ Turnpike - northbound this morning (between 7am and 8am), there were 3 truckers that did not adhere to the sign that advised no trucks in the left lane. One of your trucks was one of them. Not only did he move to the left lane, he did it suddenly cutting a car off (who had to hit the brakes hard to keep from hitting the truck) and without using a turn signal.
