Ok...pretty good coverage of excessive overloads and weird cargo.
Just as important, maybe more so...is unsecured cargo. "Just throw it in the back...no time to tie it down...it'll be fine"
I remember almost hitting an black recliner chair in the middle of I-35 one dark night... Seriously folks, they ought to make you get a license before you can drive on highway....oh wait...nvm.
Had the exact same thing happen to me on I 35 a few years ago, swerved to miss it...
