Car phone accessories help you stay connected, navigate, and keep your device charged while you are on the road, but they must never pull your attention away from driving. The National Highway Traffic Safety Administration (NHTSA) reports that distracted driving claimed 3,208 lives in 2024 and injured another 315,167 people. Any activity that diverts your eyes, hands, or mind from the task of driving increases your crash risk, and handling a phone is one of the most dangerous distractions. Choosing the right accessories and using them responsibly can make your drive safer and more convenient.
Understanding the risks of distracted driving
NHTSA defines distracted driving as any activity that takes attention away from safe driving, including talking or texting on a phone, eating, adjusting the stereo, or interacting with a navigation system. According to the agency, sending or reading a text takes your eyes off the road for about five seconds. At 55 miles per hour, that is equivalent to driving the length of an entire football field blindfolded. The Governors Highway Safety Association (GHSA) notes that at any given daylight moment, more than 537,000 U.S. drivers are visibly manipulating a handheld device while driving, a figure that underscores how common the behavior remains.
Both NHTSA and GHSA emphasize that the true number of distraction-related crashes is likely higher because distraction is difficult to prove at a crash scene. GHSA’s message to all drivers is straightforward: do not use cellphones or other electronic devices while driving, regardless of the current law. Keep your hands on the wheel and your eyes and mind on the road.
State laws on handheld phone use and texting
Laws vary widely across the United States, and GHSA tracks them at the state level. As of its latest update, 33 states, the District of Columbia, Puerto Rico, Guam, the Northern Mariana Islands, and the U.S. Virgin Islands prohibit all drivers from using handheld cellphones while driving. Most of these are primary enforcement laws, meaning an officer can cite a driver for that offense alone. Text messaging bans are even more widespread: 49 states, D.C., and the territories ban text messaging for all drivers, and all but six have primary enforcement.
GHSA points out that texting-only bans can be difficult to enforce because a driver may claim they were dialing a number rather than texting. For that reason, the association recommends that states prohibit handheld cellphone use by all drivers. Some states also restrict all cellphone use for novice drivers and school bus drivers. GHSA notes that 36 states and D.C. ban all cellphone use by novice drivers, and 25 states and D.C. prohibit it for school bus drivers.
Because state laws change and local ordinances may add further restrictions, GHSA advises checking the rules in your own state. NHTSA directs drivers to the GHSA website to learn about the laws where they live. Before you travel, a quick review of the current regulations can help you avoid fines and drive more safely.
Set up mounts and navigation before you start the engine
A phone mount is one of the most useful car phone accessories you can own, but it only improves safety when used correctly. Mount your phone in a fixed position that lets you glance at the screen without taking your eyes far from the road. Position the mount so it does not block your view of the windshield or dashboard instruments. Complete all navigation entries, music selections, and call setups while the vehicle is parked. Once you are moving, do not handle the phone. If you need to change a setting, pull over safely first.
Many drivers find that a well-placed mount reduces the temptation to pick up the device. Some states also regulate where windshield mounts can go, so check your state’s rules, and keep the phone within your line of sight but not in a spot that obscures traffic, signs, or pedestrians. A mount that attaches securely to the dashboard, a vent, or the windshield can keep the phone stable and accessible. For more on phone holders and stands, see our phone stands guide.
Car charging with USB Power Delivery
Keeping your phone charged on the road is essential, especially when you rely on it for navigation. The USB Implementers Forum (USB-IF) oversees the USB Power Delivery (USB PD) specification, which enables faster and more flexible charging over a USB Type-C connection. According to the USB-IF, the USB PD Revision 3.1 specification, announced in 2021, can deliver up to 240 watts of power over a full-featured USB Type-C cable and connector. Before that update, USB PD was limited to 100 watts using a 20-volt solution with cables rated at 5 amps.
USB Power Delivery introduces several features that matter for in-car charging. It supports new fixed voltages of 28V, 36V, and 48V, which enable power levels up to 140W, 180W, and 240W respectively. An adjustable voltage supply mode lets the connected device request intermediate voltages between 15V and the charger’s maximum fixed voltage. The specification also allows power direction to be flexible, so a device can either receive or provide power depending on the situation. These capabilities mean a single car charger can efficiently power a phone, a tablet, or even a laptop, provided the charger and cable are built to the appropriate USB PD standard.
When shopping for a car charger, look for products that have passed USB-IF compliance testing and appear on the Integrators List. The USB-IF notes that companies wishing to use the certified USB logos must have a current USB-IF Trademark License Agreement on file. A charger with the certified logo gives you confidence that it has been checked for safety and interoperability.

What to consider in a car charger and cable
Beyond USB PD support, a few practical points can help you pick a charger that works reliably in a vehicle. The charger should fit snugly in your car’s 12V accessory socket and stay put even on bumpy roads. A compact design that does not protrude too far can prevent accidental knocks. The cable you pair with the charger matters just as much. A USB-IF certified cable rated for the power level your phone or tablet requires will deliver the expected charging speed and reduce the risk of overheating. If your device supports fast charging through a proprietary standard on top of USB PD, check that the charger and cable are compatible with that standard as well; our compatibility guides can help you sort through the options.
Since a car charger stays plugged in for long periods, it should be built to handle temperature swings inside a parked vehicle. While no single certification covers every environmental extreme, choosing a charger from a reputable brand that follows USB-IF guidelines is a sensible starting point. Avoid chargers with loose connections or flimsy housings, as they can fail or damage your device’s charging port.
Staying hands-free beyond the mount
Many newer vehicles include built-in Bluetooth for hands-free calling and audio streaming. If your car does not have that feature, a Bluetooth adapter that plugs into the auxiliary input or a USB port can add hands-free capability without requiring you to touch the phone. Voice assistants built into smartphones can also read messages aloud and let you dictate replies, but NHTSA counts anything that takes your attention away from driving as a distraction. The safest approach is to keep conversations brief and avoid complex tasks while driving.
Remember that any mobile accessory you bring into the car should support the goal of keeping your hands on the wheel and your focus on the road. A mount, a charger, and a hands-free connection are tools, not guarantees. Your own habits make the biggest difference.
Frequently asked questions
Is it safe to use a phone mount while driving?
A phone mount can improve safety by holding the device steady and within your line of sight, but only if you set it up before driving and do not interact with the screen while the vehicle is moving. NHTSA warns that any visual, manual, or cognitive distraction increases crash risk. Position the mount so it does not block your view, and resist the urge to touch the phone.
What should I look for in a car charger?
Look for a charger that supports USB Power Delivery and has been certified by the USB-IF. The USB-IF states that certified products have passed compliance testing and are listed on the Integrators List. A charger with the certified USB logo is more likely to deliver safe, reliable power. Also choose a cable rated for the power level your device needs, and make sure the charger fits securely in your vehicle’s power socket.
Do all states ban handheld phone use while driving?
No. According to GHSA, 33 states and several territories prohibit all drivers from using handheld cellphones, but the remaining states have either partial bans or no handheld ban at all. Text messaging bans cover 49 states. Because laws differ and can change, GHSA recommends checking your state’s current rules before you drive.
