Hello,
I've done the search and couldn't find any info here using the front nose mask and the CA carpool sticker that affixes on the front bumper.

Do I get a $370? minimum ticket if the CHP doesn't see it up front? I don't want to waste their time, but I'll have 3 other stickers on the rear.

Please let me know your thoughts because spending a lot of time on the 405 produces lots of chips/scratches/dents etc. on my other cars.

TIA,
Mike G.

Good q. I wonder. I'm not even going to bother putting all of them on there, thats just absurd. Maybe the ones in the back, but DEFINITELY not in the front....

i only have one sticker on the rear and have had no problems at all, even got pulled over because they thought i was driving solo, told them there was a hybrid sticker on the back, they went to look and told me to hop back in the carpool lane and apologized. Worst thing that i can think they can do is give you a fix0it ticked for not following the instructions, they cant give you a carpool ticket cause you have a hybrid and have the registration card and stickers to prove it, and if they do, the judge will throw it out.
