You are learning, which is a good sign. Dispatch said nothing because you were right, they were wrong. But, if you were not aware of the rule or kept your mouth shut, dispatch will take advantage of it every time. You violate hours of service, have an accident, you are responsible, not dispatch. Pick up a trailer with bills showing to much weight. You not dispatch takes the heat. A case in Indiana found the driver totally @ fault. In the eyes of the court & law, you should know the weight limit of you rig. When you sign the bills you have accepted responsibility. Ignorance of the law is not a defense. Never hesitate to ask Management if you think something is wrong. Make 1 big mistake, & you might never work in this business again. Amazon has the best price for a hand held recorder. A drivers best friend. Also many apps in a smart phone to record conversations. Each state has a different law on recording. Know yours. Good luck. von.
