This thing has been around for years...
If you watch for awhile you'll see a trend, white cars, four doors, pick up trucks. They have two officers standing near the entrance to the ramp pointing cars in.
If you have a recent smog cert (90 days) you can show it and they'll spit you out.
If you're tagged it's a fix it ticket yes but there is no longer any free rides, it'll cost you money to have it taken care of.
And that location, if they close one lane for inspections, it'll **** up that intersection right quick. All you need is one funeral and it'll be grid lock madness.
