Here in DUH- common-wealth there's a requirement to ticket so many violation in a given period, to prove you actually are looking for problems this usally occurs around the 29-31, hence the term making quota, or what is the flavor of the week example : inspection stickers each officer needs to get 10 this week... sometimes the troopers hang out at the exit ramps so your trapped and they really run up the quota. this usally involves a warning and a fine plus you need to find a garage that isn't backed up for 2 days trying to complete this months inspections prior to the deadline.
Some garages like to offer new tires, brakes, tail-lights, exhaust systems. I feel this is good for the economy so I usally unplug a light or place a blown bulb in the outlet this prevents the need for the more expensive repairs like brakes, and tail pipes.
