AZ DPS does it, but not very often in the Phoenix metro area. Those guys are hella busy taking accident reports.
Several years back, they added a Roadside Motorist Assistant classification where civilians drive vehicles specially designated with "Motorist Assistant" and help out with broken down vehicles. I don't know how prevalent they are statewide, though.
And to the OP - I agree, it's nice to see a Jefe jumping in and helping out. That's awesome.
We've got good peeps like that here in our forum, too.
Of every one hundred men, ten should not even be here. Eighty are nothing but targets. Nine are real fighters, and we are lucky to have them, for they make the battle. Ah, but the One... One of them is a Warrior... He will bring the others back.
"Wrong door, buddy!"
Let no man's ghost say my training failed him.
