Re: Exhaust emission control information

It was common to see roadside inspections by the CHP. They'd check your headlight aim, operation of all the lights, and look for obvious bypassing of emission controls. I always thought that the headlight aim part was bogus, because I don't expect that they would have calibrated the equipment for a non-level area. We had a designated spot for aiming headlights when I worked as a mechanic. It was set dead level as opposed to 1/8" per foot slope, like most driveways and such.
