nope, CA is very picky about stickers in any windows. Here is the few places you can put them:
- Do not block your view by putting signs or other objects on the front windshield or the back side windows. Do not hang objects on the mirror. Windshield/window stickers, etc., are permitted in these locations only:
- A seven-inch square on either the passenger’s side windshield lower corner or the lower corner of the rear window
- A five-inch square on the lower corner of the driver’s side window.
- The side windows behind the driver.
- A five-inch square located in the center uppermost portion of your windshield for an electronic toll payment device.
CA is just picky in general about cars :/
That's for the windshield in front of the vehicle and defined in California Vehicle Code 26708 (b) (3).
(3) Signs, stickers, or other materials that are displayed in a
seven-inch square in the lower corner of the windshield farthest
removed from the driver, signs, stickers, or other materials that are
displayed in a seven-inch square in the lower corner of the rear
window farthest removed from the driver, or signs, stickers, or other
materials that are displayed in a five-inch square in the lower
corner of the windshield nearest the driver.
The rear window is exempted in California Vehicle Code 26708 (b) (8) as long as it has side mirrors on both sides of the vehicle.
California Vehicle Code 26708 (b) (8) The rear window or windows, if the motor vehicle is equipped
with outside mirrors on both the left- and right-hand sides of the
vehicle that are so located as to reflect to the driver a view of the
highway through each mirror for a distance of at least 200 feet to
the rear of the vehicle.
