Can I Put a Phone Holder on My Windshield? Rules, Risks, and Alternatives
You often can, but it depends on your state’s laws and exactly where on the windshield you put it. Many states have rules against objects that obstruct the driver’s view through the windshield, and some only allow devices in small, specific areas. California, for example, allows phones only in small zones in the lower corners of the windshield. If you’re not sure about your state, a dashboard, air vent, or cup holder mount avoids the question entirely, as long as it doesn’t block your view.
Here’s what to check, the practical pros and cons, and the alternatives.

How Windshield Rules Typically Work
State rules vary, but they tend to fall into a few patterns:
- General obstruction rules: prohibit anything that blocks the driver’s clear view through the windshield.
- Specific allowed zones: permit devices like GPS units or phones only in defined areas, often the lower corners.
- Hands-free or handheld rules: limit how you can touch a phone while driving, even when it’s mounted.
California is a well-documented example. Its Vehicle Code section 26708 allows a portable GPS in a 7-inch square in the lower corner farthest from the driver, or a 5-inch square in the lower corner nearest the driver outside the airbag zone, and California’s phone law points to those same zones for windshield-mounted phones. Our guide on whether it’s legal to mount a phone on the windshield in California covers it in detail.
How to Check Your State’s Rules
- Search your state’s vehicle code for terms like “windshield obstruction,” “material obstructing view,” or “GPS mounting.”
- Check your state DMV or highway safety office website for guidance on phone use while driving.
- Look for any rules on handheld phone use, since many states limit touching a mounted phone too.
- When in doubt, choose a dashboard or vent mount that clearly doesn’t block your view.
Pros of a Windshield Mount
- High visibility: the phone is closer to your natural line of sight.
- Works in cars with awkward dashes: curved or textured dashboards can make dash mounts hard to fit.
- Easy to adjust: long arms let you position the phone precisely.
Cons of a Windshield Mount
- Can block your view: a phone high or central on the glass creates a blind spot.
- Legal restrictions: some states limit windshield placement.
- Suction can fail: heat and cold affect suction cups, and a mount can drop during a drive.
- Glare and heat: the phone sits in direct sunlight, which can make it overheat.
- Distraction risk: NHTSA notes that sending or reading a text takes your eyes off the road for about five seconds. A mount helps only if you don’t interact with the phone while driving.
If You Do Use a Windshield Mount
- Mount it low in a corner, not in the center or directly in front of you.
- Keep it out of airbag deployment zones.
- Clean the glass before attaching the suction cup.
- Check the grip regularly, especially in hot or cold weather.
- Set navigation before you drive.
Alternatives to a Windshield Mount

| Air vent mount | Compact and easy to remove |

Frequently Asked Questions
Is it illegal to have a phone holder on my windshield?
Not necessarily. It depends on your state and where it’s mounted. Some states allow it in specific zones, while others restrict objects that block your view.
Can I get a ticket for a windshield phone mount?
In some states, a mount that obstructs your view or is outside allowed zones could lead to a citation. Check your state’s rules.
Is a dashboard mount always legal?
Dashboard mounts are generally less restricted, but they still shouldn’t block your view of the road.
Why does my windshield phone mount keep falling off?
Dirty glass, temperature changes, and old suction cups are common causes. Clean the glass, reseat the mount, and replace worn suction cups.
The Takeaway
You can put a phone holder on your windshield in many places, but only where your state allows and where it doesn’t block your view, typically a low corner. If you’re unsure, a dashboard, vent, or cup holder mount is the simpler, lower-risk choice.
