I do not care that there are two people in your car. If you decide to move yourself over in to the carpool lane, you need to be going faster (or at least the same speed) as traffic on the rest of the freeway. Moving over into the carpool lane and then proceeding to drive 10mph SLOWER than everyone else is NOT kosher. It’s especially not kosher when you have oversized boards sticking out the back of your truck. Yes, you should in fact be going slow, but there is NO need for you to be in the carpool lane.
