The first T-shirts in history weren’t meant to be worn at all—they were underwear. They started as simple cotton undergarments for laborers, evolved into military wear, and slowly transformed into a universal everyday item. Their evolution is a reminder that something as ordinary as a piece of clothing can reinvent itself when society finally recognizes its purpose.

For me, the concept of impaired driving has undergone a similar transformation. When I was much younger, I thought impaired driving simply meant “drunk driving.” But as I grew up, especially after leaving Iran and experiencing the chaos of American roads for the first time, the definition expanded. Impaired driving, to me, means any state in which your ability to be responsible for another life—your own and others’—is weakened. It is the moment when the mental “fabric” that holds attention, reflexes, and judgment together becomes worn, stretched, or torn.

It is also one of the most misunderstood dangers on the road—even among people who consider themselves good, educated drivers. Many believe that passing a driver’s ed course once is enough. But awareness fades, confidence inflates, and subtle impairments—fatigue, emotional distress, dehydration, medication—are often overlooked. Some drivers don’t recognize impairment because they expect it to look obvious. But like the earliest T-shirts, impairment doesn’t announce itself. It quietly sits underneath everything you think you are doing right.

Today, drivers face four major impairments: alcohol, drugs, fatigue, and distraction. Alcohol and drugs alter perception, slow reaction times, and weaken judgment. Fatigue mimics intoxication—it blurs vision, reduces alertness, and creates delayed responses. And distraction, especially texting, divides the brain in ways we are neurologically not built to handle. We imagine we can “glance quickly,” but neuroscience shows that returning full focus takes several seconds. At 60 mph, that’s the length of a football field—driven blindly.

I first understood the real meaning of impaired driving when someone in my community back home in Iran—a young woman only two years older than me—was hit by a fatigued driver who had worked a double shift. He fell asleep behind the wheel for less than two seconds. She never walked again. That accident reshaped something in me. It taught me that driving is never just personal transportation; it is a public responsibility. It also taught me that “I’m just tired” is not an excuse—it is a life-altering risk.

Since then, every time I sit behind the wheel, I think of how a two-second window changed her entire life. My choices behind the wheel are shaped by that memory. I pull over when I’m tired, I never text, and I speak up when someone else is driving carelessly—even if it’s uncomfortable. Silence, I learned, can also be a form of impairment.

Driver’s education and traffic safety courses have a powerful role in reshaping these attitudes. They work because they connect abstract danger to human consequences. They show real stories, real data, real faces. They deconstruct myths—like “I’m fine after one drink” or “I drive better when I’m tired because I’m more focused.” A strong traffic-safety curriculum teaches decision-making, not just rules. It prepares drivers for the unpredictable: distracted pedestrians, sudden weather changes, emotional driving, pressure from peers.

What makes these programs effective in real life is repetition. Just like CPR training, driver safety must be revisited. We need booster sessions, updated modules, and annual refreshers—especially as our roads become more complicated with electric vehicles, autonomous features, and faster speeds. Education cannot be a one-time formality; it must be an evolving practice.

My own role in preventing impaired driving begins with education, especially for young drivers. I have taught children and teenagers in many subjects—math, science, technology—and I’ve learned that stories and analogies reach them better than rules. If I can teach satellite-imagery AI models through the AI4ALL Ignite program, I can also teach students how to recognize their own impairments. If I can help underprivileged kids understand physics through storytelling, I can help new drivers understand that their brain is not a machine—it tires, cracks, and fails long before they notice.

I plan to use my voice, my teaching experience, my community-work background, and my academic path in engineering and AI to create safety workshops, informational guides, and simple, shareable resources that help new drivers identify hidden impairments. I envision using technology—maybe even AI—to detect fatigue patterns or dangerous micro-behaviors earlier.

Just as T-shirts evolved once society recognized their potential, our driving culture can evolve once we understand that safety is not a rule—it’s a mindset.

Impaired driving is preventable. But prevention requires constant education, personal responsibility, and the courage to intervene. My commitment is to play whatever part I can—through teaching, through advocacy, through innovation—so that fewer stories end the way hers did.
