OHV GREEN STICKER VS RED STICKER
How do you tell if a dirt bike is red or green sticker?
Typically dirt bikes and ATVs intended by the manufacturer for mostly trail type/non-competitive riding will meet green sticker emissions. Red sticker OHVs are model year 2003 and newer that are not in compliance with California OHV emissions. You can identify a red sticker OHV by looking at its VIN number.
Can you make a red sticker a green sticker?
No. If there is a "3" or "C" in the eighth position of the Vehicle Identification Number (VIN), if the vehicle does not meet the emission standards. If your vehicle has a 3 or a C, then DMV should issue you a Red Sticker instead of a Green Sticker. The bottom line, check your VIN.
