Well, you can and you can't. I've never had anyone actually check the paperwork that goes along with the pass to match it to the sled.
 
mod bring yur sleds for the gun and i got spare sleds to trail ride and bring your friend too! i got lots of place to sleep thats if you can make it out of the shed !!!!!sometimes i sleep there!!!!!!!lol!!!!!!!!!lmao!!!!!!

i got spare trail pass on 01 windsheild with paper work
 
You need a sticker here as well. I'll show you a trick if you come up, and you'll never put one on your windshield again.
