CRIT OHV Stickers:

If you will be operating an OHV vehicle while on Colorado River Indian Tribe (CRIT) land, it must be registered with the CRIT and have a “CRIT OHV Sticker” attached to the vehicle.

Please note, this is a different sticker than a Parker 400 parking, camping or vehicle pit pass sticker.

• Race Vehicles on Race Day: No, you do not need to obtain a CRIT OHV Sticker for your race vehicle on race days.
• Poker Run / Pre-Run Vehicles: Yes, you need to obtain a CRIT OHV sticker for participating in the Poker Run and pre-running.

What exact information do you need to obtain a CRIT OHV Sticker?

• Registered Vehicles: Vehicle registration.
• Non-Registered Vehicles: Vehicle Title or rental agreement if it is a rental. Anything with the VIN number. If you don’t have a VIN number on your vehicle, you will need a notarized letter with year, make and model description of the vehicle with your name and address on it.
