What is the Most Common Type of Collision Between Cars and Motorcycles?
October 06, 2025
Motorcycles are fast, nimble, and exposed. And when they’re in traffic with bigger, heavier cars, the risk of an accident goes way up. But what is the most common type of collision between cars and motorcycles? The answer might surprise you, and knowing it could help prevent serious injuries or even save a life.
The #1 Cause: Cars Turning Left in Front of Motorcycles
So, what is the most common type of collision between cars and motorcycles? The answer is straightforward, and unfortunately, far too common: Most crashes between motorcycles and passenger vehicles happen when a car makes a left turn in front of a motorcycle. These types of accidents usually occur at intersections. Picture this: a driver is waiting to make a left turn, and a motorcycle is heading straight through the intersection from the opposite direction. The driver thinks they have time to turn, but they don’t. The car cuts across the path of the motorcycle, and the rider has nowhere to go. The result? A high-impact crash that can cause serious injuries to the motorcyclist.Why Does This Happen So Often?
This isn’t a rare mistake. In fact, left-turn collisions account for the largest share of motorcycle-related crashes involving other vehicles. They’re not just common, they’re dangerous. Here’s why they keep happening:Motorcycles Are Harder to See
Motorcycles are much smaller than cars. From a distance, especially at dusk or in bad weather, they can be hard to notice. Drivers are often looking for other large vehicles, not a narrow bike with one headlight. And when drivers aren’t expecting to see something, they’re more likely to miss it entirely.Drivers Misjudge Speed and Distance
Even when a driver sees the motorcycle, they may not realize how fast it’s moving. It’s easy to misjudge how far away a motorcycle is, especially when it's coming straight at you. Many left-turn crashes happen because the driver underestimates how quickly the motorcycle is approaching and thinks they have time to complete the turn.Intersections Are High-Stress Zones
Think about how much is going on at a busy intersection: traffic lights, pedestrians, cross traffic, bike lanes, signage. Drivers trying to turn left are often watching multiple directions at once. With so much happening, it’s easy to make a rushed decision, and miss something critical, like an oncoming motorcycle.The “Gap Mentality”
Here’s something you may not have thought about: when drivers look for a chance to turn left, they’re often scanning for gaps in traffic, not necessarily for motorcycles. If a bike is small enough to “fit” in a gap between cars, some drivers simply don’t register it as a vehicle that needs to be avoided. These collisions often result in some of the most serious injuries seen in motorcycle accidents, including broken bones, head trauma, and road rash.What Makes These Crashes So Dangerous?
A car-vs-car crash at low speeds might result in a dented bumper or a sore neck. But when a motorcycle is involved, the outcome can be far more serious. Here’s why:- Motorcyclists are fully exposed. There’s no metal frame, seatbelt, or airbag to protect them.
- The impact throws the rider. Many riders are ejected from the bike upon impact and can hit the ground, other vehicles, or nearby objects.
- The motorcycle can slide or flip. If the front wheel strikes the side of a turning car, the bike may topple over or slide, increasing the chance of injury.
- Cars are often turning across multiple lanes. If other vehicles are moving nearby, the rider might be hit again or dragged, making injuries even worse.
- A car is stopped with its wheels turned left
- The driver is creeping into the intersection
- There’s a gap in traffic, and you might be “hidden” behind another vehicle
- The driver isn’t making eye contact or looking your way
Why Are Left-Turn Accidents So Common?
If you’re wondering what is the most common type of collision between cars and motorcycles?, the answer points directly to left-turn accidents. But why do these types of crashes keep happening, and why so often between motorcycles and cars? The truth is, a lot of it comes down to visibility, timing, and how people make decisions at intersections. Here’s a deeper look at the reasons behind these common collisions and what both drivers and riders should know to stay safer on the road.1. Motorcycles Are Easier to Miss Than You Think
It’s not just carelessness, even good drivers can miss seeing a motorcycle. Here’s why:- Size matters. Motorcycles are much smaller than cars and trucks, which makes them harder to see, especially from far away.
- They’re easy to lose in clutter. A bike can blend into the background of buildings, traffic signs, or parked cars. And at night or in bad weather, that visibility gets even worse.
- They’re quick. Motorcycles can accelerate fast and change position quickly, making it harder to predict where they’ll be.
2. Judging Speed and Distance Is Harder With Motorcycles
Most drivers are used to judging how fast another car is moving. Cars have two headlights spaced apart and a larger body, which helps our brains gauge how far away they are. Motorcycles? Not so much.- A single headlight can make a bike look farther away than it really is.
- Slim frames can make motorcycles appear to be moving slower than they are.
- Fast closing distance means that if a driver misjudges even by a few seconds, a crash can happen before they know it.
3. Intersections Are Overwhelming, and That’s Part of the Problem
Think about what happens at a typical intersection:- You’ve got traffic lights changing
- Pedestrians crossing
- Bikes in the bike lane
- Cars behind you honking
- Maybe even kids in the backseat asking for snacks
4. Drivers Look for Gaps, Not Motorcycles
Here’s something that’s not talked about enough, and it's key to understanding why this type of crash is so common. When drivers want to turn left across traffic, their brains aren’t always scanning for individual vehicles. Instead, they’re looking for gaps. A gap between two cars might seem big enough to turn through, but if there’s a motorcycle in that space, it can go completely unnoticed. This “gap-based thinking” causes drivers to miscalculate the situation, and that’s when a crash happens. It’s a mental shortcut. Drivers aren’t intentionally ignoring motorcycles, they’re just using a faster (and riskier) way to make decisions. Unfortunately, that can have serious consequences when a rider is in the blind spot of that judgment call. Do these crashes happen more in cities or on highways? Left-turn crashes are most common in urban areas, especially at intersections with traffic signals or stop signs. Cities with lots of stop-and-go traffic increase the chances of these incidents. Who’s usually at fault in a left-turn crash? In most cases, the turning driver is expected to yield to oncoming traffic. However, every situation is different, and fault depends on the details, like speed, visibility, and right-of-way. This is why it’s so important to document what happened after a crash. Can riders do anything to avoid being hit? Riders can reduce their risk by slowing down at intersections, using high-beam lights in the daytime, and riding in a lane position that increases visibility. But it’s important to remember, it’s not always within the rider’s control.Other Common Types of Motorcycle-Car Collisions
While left-turn crashes are the most common type of collision between cars and motorcycles, they aren’t the only danger riders face on the road. There are several other types of accidents that happen regularly, and understanding how they occur can help both drivers and motorcyclists avoid them. Let’s break down these other common collision types, what causes them, and what can be done to reduce the risk.Lane Change Crashes
How it happens: A driver decides to switch lanes but doesn’t check their blind spots or side mirrors carefully. A motorcycle is already in the next lane, but the driver either doesn’t see it or assumes it’s not close enough to be a problem. Suddenly, the car drifts over, and the rider has nowhere to go. Why it’s dangerous: Motorcycles are smaller and harder to spot. If a driver doesn’t take the time to double-check, the rider may be forced off the road or sideswiped, which often leads to serious injuries.Rear-End Accidents
How it happens: A driver follows too closely behind a motorcycle. The rider slows down, maybe to turn or avoid a pothole, and the car behind can’t stop in time. Why it’s dangerous: Motorcycles can stop faster than cars. A rear-end crash that might just dent a bumper in a car-to-car collision can be devastating to a rider. Even at low speeds, the impact can throw a motorcyclist off the bike.Dooring Incidents
How it happens: A driver or passenger in a parked car swings open their door into traffic without checking the side mirror first. A motorcycle comes along, and hits the door head-on. Why it’s dangerous: Riders often travel closer to parked cars than other vehicles do, especially in cities. When a door suddenly opens, there’s no time to react. These incidents often happen at low speeds, but they still cause serious injuries.Unsafe Passing
How it happens: A driver tries to pass a motorcycle on a two-lane road or highway but doesn’t leave enough space, or tries to pass on a curve or hill where visibility is poor. Why it’s dangerous: If there isn’t enough room or the driver misjudges timing, the motorcycle can be hit, pushed off the road, or forced into oncoming traffic. These crashes often happen at higher speeds, which increases the severity of injuries. If you do find yourself in any of these situations, knowing what to do and what to avoid after a motorcycle accident can protect both your health and your legal rights.What Riders Can Do to Avoid These Crashes
Riders don’t have control over what other people do, but they can ride in ways that reduce risk. Here are some smart strategies:- Be seen. Wear bright or reflective gear. Keep your headlight on, even during the day. Consider adding auxiliary lights or a high-visibility vest.
- Avoid blind spots. Stay out of areas where you can’t be seen, especially near large vehicles or in multi-lane traffic.
- Stay alert at intersections. Slow down and watch for turning cars, even if you have the right of way.
- Watch for movement. If you see a car’s wheels turning or edging forward, prepare to brake or swerve, they might not see you.
- Use your lane wisely. Ride in a lane position that makes you most visible to other drivers. This might mean riding in the left or center portion of your lane.
- Use high beams or your horn as needed. Don’t be afraid to make yourself known. A quick honk or a flash of your lights can prevent a crash.
What Drivers Can Do to Help Prevent Motorcycle Accidents
Motorcycle safety isn’t just the rider’s responsibility. In fact, many of the most common motorcycle-car collisions are caused by the driver. Here’s what drivers can do to make the roads safer:- Look twice before turning left. This simple habit can prevent the most common and deadly motorcycle crashes.
- Check blind spots before changing lanes. Motorcycles can hide in your side mirrors. A shoulder check can make all the difference.
- Leave extra space. Don’t tailgate. Give motorcycles more following distance than you would a car.
- Pass with care. Don’t rush or squeeze by. Always use your turn signal, and make sure there’s plenty of room.
- Respect the full lane. Motorcycles are legally allowed to use the entire lane. Don’t crowd or “share” the lane with them.
