A common yet dangerous scenario occurs when a driver performs all the proper visual checks before making a left turn, only to collide with a motorcyclist they claim wasn’t visible. These ‘looked but failed to see’ accidents represent one of the most frequent and serious types of motorcycle collisions. The root cause lies in inattentional blindness (IB), a well-documented psychological phenomenon wherein individuals fail to perceive unexpected stimuli when their attention is engaged elsewhere.
The Science Behind Inattentional Blindness
Inattentional blindness was famously demonstrated in the “Invisible Gorilla” experiment by psychologists Simons and Chabris. Participants watching a basketball game completely missed a person in a gorilla suit walking through the scene because they were focused on counting passes. This same principle applies to driving.
The human brain has limited attentional capacity. When overloaded—whether by navigation, conversations, or phone use—it filters out what it deems “irrelevant.” Unfortunately, motorcycles often fall into that category because they are smaller, move faster, and are less common than cars.
Several factors worsen inattentional blindness on the road:
- Age and Experience: Older drivers may struggle more due to slower processing speeds, while experienced drivers may rely too much on automatic behaviors, missing sudden changes in traffic.
- Expectation Bias: Drivers are conditioned to look for cars, not bikes. Since motorcycles occupy less visual space, they’re more likely to be ignored.
- Cognitive Load: Even hands-free phone calls increase IB by diverting mental focus away from the road.
How Inattentional Blindness Manifests in Driving
Motorcyclists are particularly vulnerable because they occupy less visual space and move differently than cars. Some of the most dangerous scenarios include:
Left-Turn Accidents
A driver checks for oncoming cars but fails to register a motorcycle, pulling out directly into its path. The NHTSA reports that 43% of fatal motorcycle crashes involve a car turning left in front of a bike.
Lane Changes and Merges
A distracted driver checks mirrors but doesn’t “see” a bike in their blind spot, sideswiping it. This is especially common in heavy traffic where drivers are overloaded with stimuli.
Intersection Oversights
A driver focused on a green light may miss a motorcyclist running a red light (or vice versa). Because motorcycles accelerate and decelerate faster than cars, drivers often misjudge their speed and distance.
It’s important to note that inattentional blindness isn’t just about distraction—it can happen even to attentive drivers. The “Looked But Didn’t See” (LBFDS) phenomenon is a hallmark of inattentional blindness-related crashes, where drivers genuinely believe they checked properly but still missed the motorcycle.
The Deadly Consequences for Motorcyclists
The results of inattentional blindness are often catastrophic. Motorcyclists are 24 times more likely to die in a crash than car occupants per mile traveled, and many of these fatalities occur because the driver simply didn’t see them.
Legally, drivers are still held responsible in most cases, even if they claim they “didn’t see” the motorcyclist. However, this is little comfort to riders who suffer life-altering injuries—or families who lose loved ones—because of a driver’s perceptual blind spot.
Survivors of IB-related crashes often describe the horror of watching a driver look right at them… and pull out anyway. This underscores just how powerful—and dangerous—inattentional blindness can be.
Combating Inattentional Blindness
For Drivers Becoming More Aware
Drivers can train themselves to overcome inattentional blindness with better habits. First, they should actively scan their surroundings—not just quick glances, but deliberate checks of mirrors and blind spots, especially at intersections where motorcycles are easily missed. Second, reducing mental distractions is crucial. Even hands-free phone calls divide attention, so it’s better to focus solely on driving. Finally, drivers should consciously look for motorcycles, not just cars. A simple mindset shift like “Where there’s one wheel, look for two” can make a big difference.
For Motorcyclists Staying Visible
Since riders can’t control whether drivers see them, they need to maximize their visibility. Wearing bright colors like fluorescent yellow or orange significantly reduces collision risk. At night, reflective gear and always-on headlights help. Positioning matters too—riding in the left third of the lane keeps bikes more visible while avoiding blind spots. Most importantly, motorcyclists should ride defensively, never assuming a driver has spotted them, even after eye contact.
A Call for Awareness and Action
Inattentional blindness isn’t about negligence—it’s a hardwired limitation of human perception. But by understanding it, drivers can train themselves to see better, and riders can take steps to be seen. The road doesn’t have to be a battlefield. With the right knowledge and habits, we can reduce the toll of inattentional blindness—and save lives.
