Nope. The car-pool-sticker-in-the-glove-compartment won't work and they can still give you a ticket for not wearing those hideous permanent stickers. You'd only be angering the officer for whipping out the stickers thinking that he wasted his time pulling you over and he'll tell you're only allowed to drive in the car pool lane if the stickers are affixed to your car as stated in the instructions.
What I did was buy 6 of
these removable stickers (2 for each sticker) and put them on when I need to use them. I put 2 on for each sticker thinking that eventually the stickiness might start to fade on the bottom sticker and I'd just replace it. Haven't had to replace it yet, but then again, I rarely use the car pool lane.
