Another inspection question (well actually make it 2):

1. I know that a horn button must be in arm's reach of the driver, but does it have to be on the dash? I was thinking of installing it right above my e-brake.

Both hands are suppose to be safetly on the steering wheel at all times,unsafe to remove them to hit a horn button.

2. Can a car pass with an open dumptube?
