Yes, you can use decals on your car's rear window in New Jersey, but state law places clear restrictions to ensure driver visibility is not obstructed. The key regulation, N.J.S.A. 39:3-74, prohibits any material that creates a "significant obstruction" to the driver's view. This means decals are permitted as long as they are placed on the periphery of the window and do not block your sightlines to the road, mirrors, or other vehicles.
The law does not specify an exact percentage of tint or coverage, leaving it to a police officer's discretion. This subjective enforcement is the primary risk. To be safe, keep decals confined to the very edges of the window. A common guideline is to avoid placing any stickers in the area swept by the rear windshield wiper. Beyond legality, safety is paramount. A heavily cluttered rear window can create dangerous blind spots, especially when reversing or changing lanes.
| NJ Decal Regulation Summary | Key Point |
|---|---|
| Governing Law | N.J.S.A. 39:3-74 |
| Primary Rule | No "significant obstruction" to the driver's view |
| Enforcement | Subject to officer discretion |
| Common Sense Guideline | Confine decals to the outer edges of the window |
| Typical Trouble Spot | Area cleared by the rear windshield wiper |
| Potential Penalty | Ticket and fine |
It's also wise to avoid decals that imitate emergency vehicle markings or could be considered offensive, as these might attract unwanted attention from law enforcement. For complex decorative applications, like large vinyl wraps that cover windows, consulting the NJ Motor Vehicle Commission or a professional installer is recommended to ensure compliance.

















I got a ticket for this last year. My kid's sports team decals were along the top of the rear window, and I thought it was fine. A state trooper pulled me over, said it was a "visual obstruction," and wrote me a ticket. It was a hassle and a waste of money. My advice? Keep them small and stick them in the very bottom corners. If a cop thinks it's even slightly in your way, they can ticket you. It's not worth the risk.

Honestly, it's a gray area. The law says you can't have a "significant obstruction," but it doesn't define what that means with a tape measure. It's up to the cop who sees your car. I'd say if you can see clearly out of 95% of your rear window, you're probably okay. Just be about placement—don't put a big family sticker mural right in the middle. Stick to the corners and you should be fine for your daily drive around Jersey.

Beyond the headache, think about safety. Your rear window is there for a reason. Covering it with decals, even cool ones, creates blind spots. Backing out of a crowded ShopRite parking lot or merging on the Parkway is dangerous if you can't see properly. I see cars with the entire rear window covered in stickers and it's an accident waiting to happen. Follow the law, but more importantly, protect yourself and others by keeping your view clear.

I'm a stickler for a clean look, and the law is on my side for that. New Jersey's statute is designed to keep your line of sight unimpeded. From a practical standpoint, placing decals only on the extreme edges—like the top or bottom border—ensures you stay compliant. Think of it as a rule of thumb: if your decal is in the main field of view you use to check your rearview mirror, it's probably illegal. A clean, minimally decorated window is the safest bet to avoid fines and ensure safe driving.
