i suspect that if you do due diligence and try to protect the other guy, the jury will be reasonable with you on liability. if you strictly meet the requirements, and don't actually try to make your vehicles safe, then you will probably get what you deserve.
i always try my honest best to make sure i don't cause anyone else any grief, regardless of the laws, rules, or lawyers do.
Yes, Sean, i do try to follow rules and guidelines, but i first have to believe i've done the right thing as well as met the codes.
i don't worry about the feds or states. most juries won't convict an honest person who tries (unless he has a jerk lawyer). In my humble opinion.
