Left-Turn Crashes Remain a Major Threat to Motorcyclists as Protected Signals Gain Attention

Two fatal motorcycle crashes at the same intersection in Lafayette, Indiana, have prompted changes to traffic signals, bringing renewed attention to one of the most dangerous situations motorcyclists face: vehicles turning left directly into their path.

Transportation officials have implemented a protected left-turn signal at the intersection of U.S. 231 and Veterans Memorial Parkway. The change requires drivers to wait for a green arrow rather than judging gaps in oncoming traffic when making a left turn.

The deaths of Ashley Ray in June 2026 and Tyler Guy in October 2026 prompted local motorcyclists to push for improvements. The previous signal allowed drivers to turn left on a flashing yellow arrow, requiring them to judge whether oncoming traffic was far enough away to turn safely.

While the signal change addresses a specific intersection, the danger is familiar to motorcyclists everywhere. A driver who fails to see an approaching motorcycle or misjudges its speed can turn a routine trip into a fatal collision in seconds.

The Statistics Behind Left-Turn Motorcycle Crashes

Left-turn collisions are a significant contributor to fatal motorcycle crashes involving other vehicles.

A study published in Traffic Injury Prevention examined motorcycle crashes in the United States between 2017 and 2021. Researchers found that crashes involving another vehicle turning left in front of an oncoming motorcycle accounted for 26% of fatal two-vehicle motorcycle crashes.

That made this type of collision the most frequent category of fatal two-vehicle motorcycle crash examined in the study. The findings highlight how frequently a seemingly routine driving maneuver can become deadly for someone on two wheels.

The broader risks facing motorcyclists are also significant. The U.S. National Highway Traffic Safety Administration reported 6,228 motorcyclist deaths in 2024. Based on miles traveled, motorcyclists were nearly 27 times more likely to die in a motor vehicle crash than passenger vehicle occupants.

These figures measure different aspects of motorcycle safety, but together they demonstrate why preventing collisions at intersections deserves serious attention.

Why Left Turns Are So Dangerous

Several factors make left-turn collisions particularly hazardous for motorcyclists.

Motorcycles are harder to see. A motorcycle presents a smaller visual profile than a car or truck. Drivers may overlook an approaching rider, especially in heavy traffic, poor lighting, or at intersections with obstructed sightlines.

Drivers misjudge speed and distance. An approaching motorcycle may be closer or moving faster than a driver realizes. A gap that appears large enough to complete a turn can disappear in seconds.

The rider has little time to react. When a vehicle suddenly turns across a motorcycle’s path, the rider may have limited room to brake, swerve, or avoid the collision altogether.

The consequences can be severe. Unlike occupants of enclosed vehicles, motorcyclists have little structural protection when they collide with a car or are thrown from their bikes.

These risks make intersections especially important areas for both motorists and riders to approach with caution.

Can Protected Left-Turn Signals Prevent Crashes?

Protected left-turn signals give drivers a green arrow to turn while opposing traffic is stopped. Unlike a flashing yellow arrow, a protected signal does not require drivers to judge gaps in oncoming traffic during that phase.

This can eliminate a major conflict between turning vehicles and through traffic, including motorcycles.

However, protected signals are not a complete solution. Drivers must still watch for pedestrians, cyclists, and other road users, while transportation authorities must consider visibility, intersection design, signal timing, and other potential hazards.

Improved intersection design and technology that detects approaching motorcycles and warns drivers preparing to turn could also help reduce these crashes.

What Drivers and Riders Can Do

Preventing left-turn crashes requires attention from everyone sharing the road.

For drivers:

• Look carefully for motorcycles before beginning a left turn.
• Check again for approaching traffic, even after initially judging a gap to be safe.
• Never assume an approaching motorcycle is far enough away to allow a turn.
• Avoid distractions and give yourself enough time to make a safe decision.
• Follow traffic signals and never rush through an intersection.

For motorcyclists:

• Approach intersections expecting that a vehicle could turn across your path.
• Maintain a safe speed and leave room to brake when possible.
• Watch the front wheels and movement of vehicles waiting to turn.
• Use your headlight and consider high-visibility or reflective gear to improve conspicuity.
• Remember that having the right-of-way does not guarantee that another driver will yield.

A Routine Turn Can Have Deadly Consequences

The changes in Lafayette illustrate how individual crashes can prompt communities to reconsider whether their roads are designed to protect vulnerable road users.

The underlying problem is not limited to one intersection. Wherever vehicles cross opposing traffic to make a turn, the possibility exists for a driver to misjudge an approaching motorcycle.

Protected signals, better intersection design, improved driver awareness, and defensive riding can all play a role in reducing the risk.

For motorcyclists, the consequences of a driver’s split-second mistake can be irreversible. For drivers, taking an extra moment to check for an approaching motorcycle could be the difference between an uneventful journey and a fatal collision.

A left turn may be an ordinary part of driving, but for an approaching motorcyclist, it can become a life-threatening situation in an instant.
