When I think about “impaired driving,” I don’t picture something extreme or dramatic. To me, impaired driving means anytime a driver isn’t fully alert or capable of driving safely. It’s not just about drinking or using drugs. People can be impaired because they’re exhausted, stressed, sick, distracted, or taking medication that makes them drowsy. Even vision issues, like struggling to see clearly at night can count as impairment. It’s basically any situation where you’re not at your best mentally or physically, and your ability to react or focus is affected.

I used to think impairment only meant drunk driving, because that’s what most people are taught. For months, especially when I was driving at night, I kept noticing that I had trouble seeing long distances. Street signs looked fuzzy, headlights from oncoming cars felt blinding, and I felt like I had to work extra hard just to focus on the road. I didn’t technically feel “unsafe,” but I definitely didn’t feel fully confident either. Once I finally got glasses, I realized just how impaired my vision had been all along. I didn’t know how much I was straining, and I didn’t realize that something as simple as blurry vision could put me into that impaired category. That experience is what made me understand that impaired driving can happen quietly, without you even noticing it.

A big reason impaired driving is misunderstood is because the education we’re given usually focuses heavily on alcohol. Especially in school we learn about DUIs, blood alcohol concentration, and legal consequences. But the other forms of impairment don’t receive the same attention. They might be mentioned once or twice in a chapter, but not in a way that sticks with people.

I feel as if that’s why so many drivers, even adults, think impairment only matters if it’s illegal. If it’s not alcohol or drugs, they assume they’re completely fine. But things like being overtired or driving while emotional can affect your brain just as much. Someone who slept three hours the night before is absolutely impaired, but society treats it like it’s normal because everyone is tired all the time. People confuse “normal” with “safe,” and that’s where the misunderstanding begins.

In my own case, I didn’t realize how much my vision impairment was affecting me until it was fixed. Before glasses, I thought nighttime driving was just “harder”, as if it was like this for everyone. But in reality, I was constantly squinting, severely struggling to judge distance, and feeling a second or two behind the road. Those seconds matter because in an instance something could go wrong. That’s impairment. And I learned firsthand that impairment doesn’t always feel like a sudden shift. It can be subtle. It creeps up. It can be something you adapt to without realizing you’re adapting.

Another major reason impaired driving is misunderstood is because society normalizes dangerous habits. For example, almost everyone uses their phone at least a little while driving, whether it’s switching a song, sending a quick text, or checking directions. Many people drive after long shifts, pull all-nighters and still get behind the wheel, or drive while upset after a stressful day. Because these behaviors are common, people forget they count as impairment. The more we see something, the less dangerous it seems, even when the risk is actually high.

There is also an emotional and psychological side to this issue. Humans like to feel in control. We don’t want to believe we’re impaired. Admitting it feels like admitting weakness or irresponsibility. So people convince themselves that they’re “fine” even when they aren’t. They don’t want to pull over and rest, or ask someone else to drive, or admit that their vision isn’t perfect. My own hesitation to get glasses is a small version of this: I didn’t want to admit that something was wrong, and I didn’t want to feel like I needed help to see clearly.

To me, impaired driving means driving without your full abilities, even if the reason seems small or harmless. It means being honest with yourself about what your mind and body are capable of in that moment. And it’s misunderstood because people think impairment is only real when it’s dramatic or illegal. My own experience showed me how easy it is to overlook something that quietly affects your driving. No matter the reason for impairment, it can make the difference between getting home safely and putting yourself or others at risk.
