Most Common Causes Of Motorcycle Collisions With Cars

Motorcycles offer freedom, agility, and excitement—but they also present unique dangers.  Riders are more exposed, less visible, and more vulnerable than vehicle occupants.  Unfortunately, many motorcycle collisions occur not because of rider error but because car  drivers fail to notice or properly respond to motorcycles.

Understanding the common causes of motorcycle collisions helps highlight preventable risks and  encourages safer roadway behavior for everyone. Below, our friends at Ganderton Law, LLC explain the most common causes of motorcycle collisions with cars.

Left-Turn Accidents: A Leading Cause 

Left-turn collisions are among the most frequent and dangerous motorcycle accidents. These  occur when a car:

• Turns left across a motorcyclist’s path
• Misjudges the motorcycle’s speed
• Fails to see the rider entirely
• Is distracted or impatient

Because motorcycles are smaller, drivers often underestimate how quickly they are approaching,  leading to devastating impacts.

Drivers Failing to Check Blind Spots 

Motorcycles can easily disappear in a car’s blind spot. Collisions commonly happen when  drivers:

• Change lanes without signaling
• Drift between lanes
• Merge suddenly
• Fail to look over their shoulder

These accidents often involve sideswipe impacts or forcing the rider off the road.

Distracted Driving 

Phones, navigation systems, music controls, and other distractions significantly increase crash  risks. Distracted drivers may:

• Miss a motorcyclist slowing ahead
• Fail to notice a rider passing
• Not see a motorcycle stopped at a light
• Drift into the motorcycle’s lane

Even a moment of distraction can lead to a serious collision.

Following Too Closely 

Motorcycles can stop more quickly than cars. When drivers follow too closely, they may not  have enough time to brake, causing rear-end collisions—often sending riders airborne.

Unsafe Lane Changes 

Drivers may:

• Change lanes without signaling
• Cut off a motorcyclist
• Weave through traffic
• Merge into a lane already occupied by a rider

These actions create especially dangerous conditions for motorcycles, which have less space and  time to react.

Speeding and Aggressive Driving 

Speeding reduces reaction time and increases crash force. Aggressive behaviors—like tailgating,  lane weaving, or sudden braking—put riders at extreme risk.

Road and Weather Hazards 

What seems minor to a car can be disastrous to a motorcycle. Common hazards include:

• Potholes
• Gravel
• Oil slicks
• Loose debris
• Uneven pavement
• Sudden rain or standing water

These hazards can cause riders to lose control, often through no fault of their own.

Rider Visibility Challenges 

Even when riders do everything right, cars sometimes overlook them because:

• They are smaller
• They blend into background scenery
• Drivers don’t expect motorcycles in their path

Lack of visibility is one of the main reasons drivers fail to yield or check properly.

Why Motorcycle Collisions Are Usually Severe 

Because riders lack a protective barrier:

• Broken bones
• Road rash
• Head injuries
• Spinal injuries
• Internal trauma

are far more likely. Helmets and protective gear help—but they cannot prevent all injuries.

A motorcycle accident lawyer knows that understanding the common causes of motorcycle collisions is a powerful step in preventing  them. Awareness, attention, and respect on the road can save lives.
