If you decided to pull a load what it is "hot load" then do not cry. You got greedy.
I was never forced to pull illegal load. Plan you trip and make shure that you have enough hours to deliver before you accept the load. You can allways say NO.
I did few times as company driver and was not penalize for. I was in apst for few other companies and did pull a "hot load", but that was my choice.
In your case-the trainer was "greedy" and forced you to do what you not supposed to do. It was not the company. You should report that trainer, but I do understand your fear of being "kick out of truck". You have to put safety above everything. What is the money good for you when you are dead or in jail.
