California drivers see air fresheners, graduation tassels, and parking passes hanging from mirrors all the time.
Whether it is legal depends on where the item is and whether it obstructs your clear view through the windshield or side windows.
Below is a practical guide to the rule, the exceptions, and how to stay ticket-free.
Understanding California Vehicle Code on Rearview Mirror Obstructions
California Vehicle Code Section 26708 makes two significant points. First, you may not drive with any object or material on the windshield or on the side or rear windows. Second, you may not drive with any object “in or upon” the vehicle if it “obstructs or reduces” your clear view through the windshield or side windows. In short, the focus is on visibility, not the specific item.
There are important exceptions. Rearview mirrors themselves are exempt. The law also allows for the placement of limited stickers or permits in small squares in the lower corners of the windshield. It specifically permits the use of devices like GPS units within defined areas of the lower windshield, provided they do not intrude into airbag zones.
Expert insight: The statute is written broadly. Hanging something from your mirror is not automatically illegal. It becomes a problem when an officer can articulate that it reduced your clear view through the windshield or side windows. Courts evaluating stops under Section 26708 look for specific, observable facts supporting obstruction.
Pro tip: If you must display a permit, use the lower-corner square areas allowed by the law for stickers or mount the license on the dashboard in a way that does not obstruct your forward field of view.
What You Can and Cannot Hang from Your Rearview Mirror
Generally risky to hang: Air fresheners, beads, tags, plush toys, and large placards can draw enforcement if they noticeably intrude on the driver’s forward field of view. Officers can initiate a stop if they reasonably believe an item on or near the windshield obstructs or reduces clear view.
Not per se illegal: A small, low-profile item that does not obstruct your clear forward view is not automatically a violation. The analysis is case-specific and depends on size, placement, movement, and where you sit. That is why two drivers with the same item can have different outcomes during a stop.
Safer alternatives:
- Place fragrance devices on vents rather than the mirror.
- Use visor clips for passes.
- Use adhesive dashboard mounts or the legally permitted lower-corner windshield areas for navigation devices, consistent with the GPS exception in Section 26708.
Pro tip: If you are unsure whether an object obstructs view, sit in your normal driving position and check a sightline from the top of the steering wheel to the right front fender and along the A-pillars. Anything that floats through that forward cone of vision is a citation risk.
Expert insight: Movement matters. A dangling item that swings can intermittently block your sightline to pedestrians, cyclists, or traffic signals, which makes “obstruction” easier to articulate in a stop report.
The Potential Consequences of Hanging Items from Your Mirror
Type of violation: Section 26708 is typically enforced as an infraction. Officers can cite if they believe an item on or in the vehicle obstructs your view, or if a device is mounted outside the permitted zones. Many citations are “correctable” if you remove the obstruction and obtain proof of correction. Penalties and local assessments vary by county.
Traffic stop implications: Even if a small item ultimately would not support a conviction, an officer can still initiate a stop where there is a reasonable, articulable suspicion of an obstruction under Section 26708. During that stop, other issues may come to light, so the safest course is to avoid the mirror entirely.
Insurance and records: A correctable equipment citation is usually less serious than a moving violation, but any stop can be inconvenient and may involve court time if you contest it. When in doubt, remove the item and document the fix.
Pro tip: Keep your proof of correction. If you receive a citation, promptly remove the item, get a sign-off if required, and follow your local court’s instructions for dismissal.

Alternatives to Hanging Items: Safe Options for Personalizing Your Vehicle
Use the permitted GPS zones. California allows a portable GPS to be mounted in a seven-inch square in the lower passenger-side corner or in a five-inch square in the lower driver-side corner of the windshield, outside any airbag deployment zone. Mounting within these areas keeps your forward field of view clear.
Prefer non-windshield placements. Consider dash-top friction mounts, center-stack cradles, or vent clips designed to keep devices out of sight below the road’s line of sight. Check that cords do not loop into your line of sight.
Keep the A-pillars clean. The combination of thick modern A-pillars and a dangling air freshener can create a larger blind zone than you realize, especially while cornering or scanning crosswalks.
Pro tip: Treat the space between eye level and the top of the steering wheel as a “no-hang zone.” Store decorations out of that corridor, and you reduce both risk and driver workload.
Expert insight: If you need to display a workplace or campus pass, choose a static dash placement that sits below the hood line from your perspective. Many institutions accept visor clips or digital credentials in an app.
Citations and Cases: Real-Life Examples of Enforcement in California
People v. Colbert (2007). The Court of Appeal upheld a stop where the officer described specific facts supporting an obstruction from an air freshener hanging from the mirror. The case illustrates that detailed, experience-based observations can satisfy reasonable suspicion under Section 26708(a)(2).
People v. Garcia (2010). The court discussed Colbert and emphasized that an officer’s specific and articulable facts about obstruction matter. Merely seeing “something” is not enough; the officer must reasonably connect the item to a reduced clear view.
People v. White (2003). The court cautioned that the absence of a statutory exception is not, by itself, dispositive. The core question is whether there was an actual or reasonably perceived obstruction of the driver’s clear view.
Why these cases matter: Together, they show that enforcement turns on practical visibility. A small tassel that does not intrude into the forward field of view is less likely to justify a stop than a larger, swinging object centered near the traffic-signal sightline.
Pro tip: If you are cited, take photos from the driver’s seated position showing your forward view without the item. If you decide to contest, those photos can help document that there was no obstruction.
Quick Takeaway and Action Steps
California law focuses on whether your forward view is obstructed, not on the mere fact that an item hangs from your mirror. Even small items can justify a stop if an officer reasonably believes they hinder your view through the windshield or side windows. The safest approach is to keep the space around your mirror clear and use legally permitted mounting zones for devices.
Action steps to stay compliant today:
- Remove all hanging items from the mirror before driving.
- Re-mount navigation devices in the permitted lower-corner zones or on the dash below your forward sightline.
- Use visor clips or vent mounts for passes and fragrances.
- If you receive a citation, promptly correct it and follow your local court’s process for proof of correction.
