Who's truck has a parking brake, who has an emergency break?

If it is not an emergancy brake, why are brake line locks illegal in california?

I have a hand brake in my Samurai. When wheeling down a steep incline on a slippery surface, I frequently use the emergency brake. This allows the front wheels to roll, resulting in more steering control, and allows for a straighter decent. I ain't parking.

You guys forgot the clearance lights.
