The best places to put car stickers are on smooth, non-flexible glass and metal surfaces where they won't obstruct your view or damage the paint. The most popular and safe locations are the rear windshield, the rear side windows, and the bumper. The absolute rule is to avoid any placement that blocks your vision through the front windshield or side windows.
Before applying anything, check your local state laws. Regulations vary, but generally, stickers cannot be placed on the windshield in the area cleared by the wipers or on the front side windows. For example, California Vehicle Code § 26708 has specific restrictions on windshield and window obstructions. The table below outlines a sample of state laws for reference.
| State | Windshield Restrictions | Side Window Restrictions | Bumper Sticker Notes |
|---|---|---|---|
| New York | Illegal within the wiper's reach | Illegal on front side windows | No specific restrictions |
| Texas | Illegal if obstructing driver's view | Tint and sticker rules enforced | Allowed, but avoid license plate area |
| Florida | 6-inch strip at top of windshield is allowed | Mostly unrestricted for rear windows | Popular and generally unregulated |
| California | Illegal in area swept by wipers | Illegal on front side windows | Must not obscure license plate |
| Illinois | Illegal if blocking driver's view | Restrictions on front side windows | Must be on the bumper, not the body |
The car's surface is also critical. Painted metal surfaces like the doors or quarter panels are not ideal for long-term placement. When removed, the sticker's adhesive can leave a residue, and the paint underneath will be a slightly different color due to sun exposure, creating a permanent "ghost" of the sticker. Glass and plastic bumpers are much safer.
For application, clean the area thoroughly with isopropyl alcohol to remove wax and dirt. Use a squeegee or a credit card to smooth out the sticker from the center outward, eliminating air bubbles. If you want the option to remove it easily later, consider using a static-cling decal instead of a permanent adhesive one.

I just stick them on the back window, bottom corner. That way, they're not blocking my view when I'm backing up. I avoid the bumper because it gets dirty and the stickers peel off faster. The main thing is to keep them off any painted metal—I learned that the hard way when I tried to remove an old one and it left a nasty shadow on my car's door.

As a parent, my priority is safety. Stickers go on the rear windshield only, placed high up or low down so they don't interfere with the rearview mirror. My kids' soccer decals are lined up neatly along the bottom edge. I would never put one on a side window because it creates a blind spot, especially when you're checking for cyclists or pedestrians before making a turn. It's all about keeping the sightlines clear.
