60 Percent Of Drivers Are Struggling With Headlight Glare

If you’ve felt like nighttime driving has gotten harsher on the eyes, you’re not alone.

A new study from AAA finds that roughly 60 percent of drivers say modern headlights create excessive glare, particularly from oncoming traffic. Despite the frustration, safety data suggests the issue may be more of a nuisance than an actual hazard.

The change is tied to two major trends: lighting technology and vehicle size. Modern cars increasingly use LED and HID headlights, which are brighter and whiter than older halogen setups. At the same time, trucks and SUVs continue to dominate the market—and their higher ride height often places headlights directly at eye level for drivers in lower vehicles.

That combination can make nighttime driving uncomfortable, especially on undivided roads.

“Headlight glare has become a major source of frustration and concern for millions of drivers,” said Greg Brannon, AAA’s director of automotive engineering and research. “As vehicle lighting technology evolves, so must our understanding of glare and its impact.”

Oncoming Traffic Is the Main Culprit

According to AAA’s findings, 92 percent of drivers who experience glare point to oncoming headlights as the primary issue. Reflections in mirrors are also a factor, with about one-third of respondents saying they’re bothered by trailing vehicles.

Certain groups report more difficulty than others. Drivers who wear prescription glasses are more likely to notice glare, and women report higher sensitivity than men. Interestingly, pickup truck drivers—who sit higher off the ground—are less likely to complain, likely because they’re less exposed to direct beam alignment from other vehicles.

Frustrating, But Not More Dangerous

Despite the complaints, there’s little evidence that brighter headlights are leading to more crashes, the IIHS says poor visibility remains a far more significant safety concern. Data from the Insurance Institute for Highway Safety (IIHS) shows that glare is cited in just one to two out of every 1,000 nighttime accidents, a rate that hasn’t increased even as lighting has grown more intense. An imperfect metric if there ever was one.

“Although it can certainly be uncomfortable, headlight glare contributes to far fewer crashes than insufficient visibility,” said IIHS president David Harkey.

Of course, one must consider that the IIHS is a huge driver of increased headlight performance through their ratings system and research. In fact, the IIHS evaluation program is focused on encouraging headlight designs that reduce the risk of nighttime single-vehicle crashes.

Which is great when you're one of the people driving those cars, but not so great for the rest of us whose eyes are bearing the brunt of your increased ability to avoid a single vehicle crash at night.

A Trade-Off in Modern Lighting

There’s also a potential upside to brighter headlights. Improved forward visibility can help drivers spot hazards earlier, and advanced driver-assistance systems like automatic emergency braking may perform better with stronger illumination.

Still, that doesn’t solve the comfort issue for drivers facing oncoming traffic. There's also a question about the effects of glare on reducing forward visibility for those who are experiencing it.

What Comes Next?

As lighting technology continues to evolve, many experts point to adaptive beam systems as a long-term solution. These systems can automatically adjust headlight patterns in real time, illuminating the road ahead while reducing glare for other drivers.
