    Those rails that hang on the back of trailers have been there since the D.O.T. enforced the law. The problem isn't the trailer but the ASSHOLES that drive to dam close to the trailer!!!!!! The so-called drivers on the road today have no common sense, I've seen it too many times that the driver of a car thinks the truck can stop as fast as the car and guess what there WRONG!!!!! We don't need a new law just smarter drivers. Give the truck a brake and give him room.

    @Bill, Thanks for the backgrounder!

    The underride guard is also known as a DOT bumper, or a Mansfield bar. The Mansfield bar name comes from a highly publicized accident involving none other than 50's icon Jayne Mansfield, in which her small car rear-ended a large truck, killing three of the six passengers including Jayne Mansfield. This took place on June 29th, 1967 – before The National Highway Transportation Safety Administration required underride guards on semi-trailers – and the car passed under the truck just high enough that Jayne Mansfield's head impacted the rear of the trailer. Popular rumor for quite some time was that she was decapitated, but in reality only a portion of her skull was severed.

    We have been complaining about this since 1980. Europe and Japan have tougher anti-underride requirements, which include lighter protection against pedestrians falling under the side of a passing truck or trailer. The trucking lobby is powerful. Added weight and cost is a no-no!

    It doesn't help that the front end of cars have been getting progressively lower for better fuel efficiency/to improve aerodynamics.

    My biggest fear for over 25 years has been just that. Rear ending a semi or worst a large trash tractor with its exposed pointed rails in the back with no protection whats so ever... Get this law passed ASAP! it is way over due...
