Pic-Walsh Freight Co., 432 S.W.2d 292 (Mo. 1968). Plaintiff, employee of an LP gas company, was not contributorily negligent as a matter of law when he overfilled an LP gas tank on one (1) of defendant’s trucks after being assured by defendant’s employees that the tank was empty; plaintiff having no way of knowing the level of gas due to broken gauge. Defendant claimed plaintiff was negligent per se because he violated safety rules concerning the filling of tanks inside a building, but court held that “all reasonable minds would not conclude that the infractions were the proximate cause of the injury in this case, and therefore . . . plaintiff is not as a matter of law barred from recovery.”
