Comment Re:Do a study FIRST. (Score 2) 90
The reason for the rules seems like common sense to me. There is a certain distance needed to stop or change lanes when driving at highway distance. If the truck breaks down just over a hill, cars won't see it early enough unless the warning signals are put further back where they can be seen coming up the hill.
I seriously doubt that these rules were just shit someone made up. The NHTSA has so many studies regarding road regulations and guidance. They might be outdated for modern technology, and might be worse than newer alternatives - I don't doubt that hasn't been studied yet - but I would absolutely wager that there were studies done to justify the original numbers.
Furthermore, when congress delegated regulatory power to these agencies they included laws dictating how the rules needed to be determined, specifically so you can't have a bunch of political hacks changing them on a whim. Changes to the regulation need to be justified, and there needs to be comment period to gather any information and concerns that the agency itself might have overlooked, respond to the comments and incorporate any changes as appropriate. I don't want regulators to be able say "this is just some crap" and change rules every four years because they shoot from the hip. That means that changes take 1-3 years depending on how complicated and motivated the agency is, but it is worthwhile to end up with better regulations and avoid being constantly jerked around.
