I pit he guy who had a dog in the back of his truck doing 90 down the freeway!

The guy hit the brakes, and the dog slid backward??? That is the most amazing thing I’ve ever read in my life.

Generally when unsecured items are in a vehicle that hits the brakes they will tend to slide forward (towards the cab). When unsecured items are in a vehicle that accelerates they will tend to slide backwards (towards the tailgate).

What Frank is asking is how did the dog slide backwards (into the tailgate) when the driver braked (broked?)?

It would violate Newton’s First Law of Motion, for one thing.

In this case, the dog is moving in the same direction as the truck, and will keep doing so until he hits the back of the cab, not the tailgate. Unless, as has been noted, the truck were moving in reverse.

ITT: Newton disproved by dog.

I’m don’t know anything about physics. Maybe the guy sped up rapidly after breaking. Or it bounced off the cab and then back to the tailgate.

I just know that the dog hit the tailgate, bounced around, and looked like it’s next step was going to be in front of my car. It scared the shit out of me and my kids. It scared the dog too–or hurt it–because it wasn’t standing in the bed anymore after that; it was laying down.

I think they just decided to break the law as flagrantly as possible in a passive-aggressive protest. It’s a “you wanna give me a ticket? I’ll give you a reason to give me a ticket” mentality. Not at all logical, but sometimes emotionally satisfying.
