Yes...if truck in front would have gotten the Green light"...your "tailgating" might have been viewed as trying to "Piggyback" the other truck.Looks very "suspicious".I've had many trucks ,try to "piggyback" off of my green light.Usually my 1st light is bypass...by the time I get to the 2nd sign it says "truck must .weigh. Totally directed at the tailgating truck.
