What is the Most Common Type of Collision Between Cars and Motorcycles?

motorcycle-car collisions

In the world of transportation, motorcycles provide an efficient and exhilarating means of travel. However, they are also more vulnerable on the road than cars, leading to an increased risk of accidents. One of the most pressing questions for road safety experts is: What is the most common type of collision between cars and motorcycles? To answer this question, we will delve into the statistics and factors that contribute to motorcycle-car collisions.

Understanding the Scope of Motorcycle-Car Collisions

To understand the most common type of collision between cars and motorcycles, we must first examine the broader picture of motorcycle accidents. According to data from the National Highway Traffic Safety Administration (NHTSA) in the United States, motorcycle accidents accounted for 14% of all traffic-related fatalities in 2021, despite motorcycles making up just 3% of registered vehicles. This stark disproportion emphasizes the significance of studying these incidents and the need to identify the most common collision types.

Common Types of Motorcycle-Car Collisions

  • Intersection Collisions: Intersection collisions are one of the most common types of accidents involving motorcycles and cars. These occur when a motorcycle and a car intersect at a junction, such as an intersection with or without traffic lights or stop signs. The motorcycle rider may be proceeding straight, turning left, or turning right. Often, the car driver fails to yield the right of way to the motorcycle or misjudges the motorcycle’s speed, resulting in a collision.
  • Lane Changing Collisions: Lane-changing collisions happen when a car changes lanes without noticing an approaching motorcycle in its blind spot or misjudges the motorcycle’s speed. These accidents often occur on highways and multi-lane roads, where cars frequently change lanes to pass slower-moving vehicles.
  • Rear-End Collisions: In rear-end collisions involving motorcycles and cars, a car strikes the rear of a motorcycle, often while both vehicles are traveling in the same direction. These accidents can occur when the car driver fails to maintain a safe following distance or does not notice the motorcycle slowing down or stopping.
  • Left-Turn Collisions: Left-turn collisions are particularly dangerous for motorcyclists. They occur when a car makes a left turn at an intersection or driveway and collides with an oncoming motorcycle. These accidents often happen because the car driver fails to see the motorcycle or misjudges its distance and speed.

Contributing Factors

Several factors contribute to the prevalence of these common motorcycle-car collision types:

  • Visibility: Motorcycles are smaller and less visible than cars, making it easier for car drivers to overlook them, especially in blind spots.
  • Speed Differential: Motorcycles can accelerate and decelerate more rapidly than cars, leading to speed differentials that car drivers may not anticipate.
  • Driver Behavior: Human error, such as distracted driving, impaired driving, or failure to yield the right of way, plays a significant role in motorcycle-car collisions.
  • Road Conditions: Poor road conditions, such as potholes, gravel, or wet surfaces, can be particularly hazardous for motorcycles due to their less stable nature.


The most common types of collisions between cars and motorcycles include intersection collisions, lane-changing collisions, rear-end collisions, and left-turn collisions. These accidents often result from factors such as reduced visibility, speed differentials, driver behavior, and road conditions. To reduce the frequency of these collisions and improve road safety for motorcyclists, both car drivers and motorcyclists must exercise caution, awareness, and defensive driving techniques. Additionally, road infrastructure and public awareness campaigns should be designed to address the unique challenges faced by motorcyclists on the road.
