Distracted driving is any activity that diverts your attention from the road while you’re behind the wheel. It killed 3,275 people in the United States in 2023, and it injures hundreds of thousands more each year. The danger comes from three types of distraction, often happening simultaneously: taking your eyes off the road, taking your hands off the wheel, and taking your mind off driving.
Three Types of Distraction
Safety experts break distracted driving into three categories. Visual distraction is anything that pulls your eyes away from the road, like looking at a phone screen or checking on a child in the backseat. Manual distraction involves removing one or both hands from the steering wheel to eat, adjust the radio, or hold a phone. Cognitive distraction is the hardest to recognize: your eyes may be on the road and your hands on the wheel, but your mind is somewhere else entirely.
What makes texting while driving so dangerous is that it combines all three. You look at the screen, tap out a message with your fingers, and think about what you’re writing. At 55 mph, a car covers roughly the length of a football field in five seconds. That’s how long a typical glance at a text message takes.
How Distraction Changes Your Reaction Time
The effects are measurable. Drivers engaged in visual-manual tasks like texting have reaction times that are 40.5% slower than undistracted drivers, adding roughly half a second to their response. That may not sound like much, but at highway speeds it translates to dozens of extra feet before you even begin to brake. A University of Iowa analysis of naturalistic driving data found that crash risk for texting drivers was 4.66 times higher than for those paying full attention to the road.
Even talking on a phone, without texting, slows you down. A meta-analysis of 33 studies found that cell phone conversations add an average of 0.25 seconds to reaction time, whether the phone is handheld or hands-free. A separate test-track study found that reading or writing a text roughly doubles reaction time compared to undistracted driving. Once reaction time exceeds about 1.5 seconds, the probability of a crash begins to climb steeply.
Why Hands-Free Isn’t Risk-Free
Switching to a hands-free device does reduce the time you spend looking away from the road and fumbling with buttons. Research comparing handheld and hands-free phone use found that hands-free technology shortens the duration of visual-manual tasks like dialing and ending a call. That’s a real benefit.
The catch is cognitive distraction. A phone conversation demands mental resources regardless of whether you’re holding the device. Your brain is processing what someone is saying, formulating responses, and maintaining the thread of a conversation that has nothing to do with the traffic around you. Hands-free setups eliminate some of the physical distraction but leave the mental distraction largely intact, which is why the reaction-time penalty shows up for both handheld and hands-free calls in the research.
Passengers vs. Phone Calls
A common assumption is that talking to a passenger should be just as distracting as talking on the phone. In practice, the two situations aren’t identical, though both carry risk. Research from the Texas Transportation Institute using a driving simulator found that both phone conversations and passenger conversations worsened driving performance compared to driving in silence. Distracted drivers of both types got closer to hidden pedestrians and pullout cars, and had slower responses to an approaching emergency vehicle.
One advantage passengers have over phone callers: they can see the road. A passenger naturally pauses when traffic gets complicated or points out a hazard. A person on the other end of a phone call has no idea you’re merging onto a highway or approaching a sudden stop, so they keep talking at the same pace and complexity regardless of what’s happening around your car.
Modern Touchscreens Add New Risk
Older cars had physical knobs and buttons for the radio, climate controls, and navigation. You could adjust the temperature by feel without looking away from the road. The trend in newer vehicles is to replace those controls with large touchscreens, sometimes consolidating nearly every function into a single display. These screens lack tactile feedback, so you have to look at them to complete even simple tasks like changing the fan speed.
Research has found that driver-centric touchscreen interfaces, like those that consolidate controls into one large central screen, lead to longer gaze durations away from the road and more frequent visual distractions compared to designs that retain some physical controls. The result is that a feature marketed as modern and convenient can quietly increase the time your eyes spend off the road during routine adjustments.
Who Is Most at Risk
Distracted driving affects every age group, but younger drivers are disproportionately represented. In 2021, 225 teens aged 15 to 19 were killed in distraction-affected crashes. Eight percent of all teen motor vehicle crash fatalities that year involved a distracted driver. Among teen drivers involved in fatal crashes, 7% were confirmed to be distracted at the time.
Teens face a compounding problem: they’re still developing the driving experience needed to recognize hazards quickly, and they’re the demographic most likely to be texting, scrolling social media, or interacting with passengers. Less experience means a smaller margin of error, and distraction eats into that margin.
State Laws on Distracted Driving
As of mid-2025, 33 states plus Washington, D.C. and several U.S. territories prohibit all drivers from using handheld cellphones while driving. Nearly all of these are primary enforcement laws, meaning an officer can pull you over solely for holding a phone. Alabama and Missouri have handheld bans but enforce them as secondary offenses, requiring another violation to initiate a stop.
The remaining states have a patchwork of rules. Some ban texting specifically but allow handheld calls. Others restrict phone use only for novice drivers or in school zones. The trend over the past several years has been toward broader handheld bans, with multiple states adding or strengthening laws each legislative session. Fines vary widely, from under $100 for a first offense in some states to several hundred dollars in others, with penalties increasing for repeat violations.
Common Distractions Beyond the Phone
Phones get the most attention, but they’re far from the only source of distracted driving. Eating and drinking behind the wheel is remarkably common. Research on driver behavior found that eating or drinking occurred more frequently during hands-free phone use than during handheld phone use, likely because drivers felt they had a free hand available. Other frequent distractions include adjusting GPS navigation, reaching for objects in the car, grooming, and rubbernecking at roadside incidents.
- Eating or drinking: Requires at least one hand off the wheel and brief glances away from the road, especially when unwrapping food or managing spills.
- Navigation adjustments: Programming a new destination while moving combines visual, manual, and cognitive distraction in much the same way texting does.
- Reaching for objects: Leaning toward the passenger seat or floor shifts your body position and your visual focus simultaneously.
- Daydreaming: Pure cognitive distraction with no obvious external cause. It’s one of the most frequently cited factors in distraction-related crashes, yet the hardest to legislate or detect.
Reducing Your Risk
The simplest strategy is also the most effective: put your phone out of reach before you start driving. Placing it in a bag in the backseat or using a “do not disturb while driving” mode removes the temptation to glance at notifications. If you need navigation, set your destination before pulling out of the driveway.
For parents of teen drivers, setting clear expectations matters. Graduated licensing programs in many states already restrict the number of passengers teens can carry, partly because of the distraction risk. Modeling good behavior is equally important. Teens who see their parents texting at red lights or scrolling through playlists in traffic absorb those habits.
If you’re shopping for a new car, pay attention to how the controls are laid out. Vehicles that retain physical knobs for climate and volume give you the option to make adjustments by touch. A sleek all-touchscreen dashboard may look impressive, but it can quietly add seconds of eyes-off-road time over the course of every drive.
