That's not really a passenger vehicle though, it's a truck (it's right there in the name "pick up truck"). Just having more seats doesn't make a truck into a "passenger vehicle", my brother used to drive a 40,000 lb heavy truck that had a crew cab that seats 6, but no one would classify that as a "passenger vehicle".

It was so heavy that when he took it home, he couldn't drive it all the way home, he had to park it a half mile away and walk because there was a bridge with a 10 ton weight limit that he couldn't cross.

I'd say most Americans see a pickup as a "passenger vehicle".

They're certainly licensed the same in my state.
