Why We Don’t Believe Distracted Driving Data (And Why We Should)

Q: I’ve heard the Traffic Safety Commission talking about how most drivers aren’t driving distracted (something like nine out of ten.) I find that hard to believe. When I look around I see people on their phones all the time. How’d you get those numbers?

A: Before I explain how we got the numbers, let’s consider why you don’t believe them. If it’s any comfort, you’re not alone. Many people, when they hear the statistic that more than nine out of ten drivers are focused on the road, reject the data as somehow flawed.

I’m guilty of it myself. Last week, while in a city I don’t visit often, I walked along the main thoroughfare and thought to myself, “Wow, every driver in this town is on their phone.” To confirm my observation I started counting. After 50 or so vehicles, I counted five drivers that were on their phone or otherwise distracted, roughly in line with the statewide results.

The problem here is the human brain. We’re wired to notice and remember the outlier rather than the ordinary. When drivers keep their focus on the road, there’s not much to notice. The distracted folks stick out. This wouldn’t be a big deal, except that misperceiving the frequency of a behavior influences our own behavior.

A study in Minnesota found that 70 percent of people think most drivers speed 10 mph over the limit, but in reality only 15 percent do. Those who believed most drivers speed were more likely to do it themselves. We tend to behave according to perceived social norms, even when we’re wrong about them. If you think most people are on their phones while driving, you might be more inclined to pick it up to respond to a call or text.

As to how we got the numbers, it’s pretty simple. Trained observers went to randomly sampled locations all over the state and counted distracted drivers. Last year, after counting thousands of vehicles, the observational study shows that about seven percent of drivers were distracted. That’s down from a high of about ten percent in 2016, when Washington first started counting. That also correlates with a decrease in fatalities involving distracted drivers. In 2015, a third of all traffic fatalities involved a distracted driver. Since then that rate has been declining, and in 2020, 18 percent of fatal crashes involved a distracted driver.

I should point out that the seven percent number is a “moment in time” statistic. It doesn’t mean that 93 percent of us never get distracted. We still have some work to do there. In a 2019 survey of Washington drivers, 35 percent said they frequently use a cell phone while driving, contrasting 62 percent of drivers who said they frequently wait to use a phone until they’re out of the flow of traffic. Even there, most of us don’t usually get distracted by our phones while driving.

Doing the math, the above data suggest that using your phone while driving roughly triples your risk of a fatal crash. As you might guess, the type of distraction is part of that equation (texting is worse than talking), and driver age is a big factor. For young drivers (I know, I’m always pointing out young drivers have it worse) talking on the phone quadruples their risk, and texting increases their risk of a fatal crash by eight or more times.

Whatever your age, distraction is one if the top factors in fatal crashes, but it’s solvable. If you’re one of the outliers, it’s time to put away the distractions and make driving your priority.

  1. This makes a lot of sense. What I find hard to believe is that the “trained observers” could even see the drivers at all! Here in South Carolina, the vast majority of vehicles (another misperception?) have window tint that rivals Darth Vader’s helmet. Or maybe too dark window tint is not as much a problem in overcast Washington state?
