Motorcycle crashes in Southern California are alarmingly frequent. With our region's year-round riding weather, scenic routes, and urban congestion, the risk factors stack up fast. For motorcyclists, understanding the common causes of these accidents isn’t just educational—it’s life-saving.

At AK Injury Law Firm, we know the stakes are high. Our founder, Dr. Azadeh Keshavarz, isn’t just an experienced personal injury attorney—she was once a doctor of chiropractic who saw firsthand how devastating and complex motorcycle injuries could be. She started this firm to outthink, outfight, and outwin insurance companies that try to undervalue real people’s pain.

Let’s examine the top causes of motorcycle crashes in Southern California and what makes these cases unique from a legal perspective.

1. Distracted Drivers

Texting, eating, adjusting GPS—drivers today are often more focused on their devices than the road. Unlike cars, motorcycles don’t have the bulk or visibility to absorb a driver’s inattention. A brief glance away from the road can result in a devastating side-swipe or rear-end collision.

Why it’s dangerous for motorcyclists: Even a slight bump from a distracted driver can throw a rider from their bike. This isn’t a minor fender-bender—it’s often catastrophic.

Legal insight: In these cases, collecting smartphone data and reviewing traffic camera footage can be crucial. At AK Injury Law, we aggressively seek this evidence early.

2. Unsafe Lane Changes

Many motorcycle accidents in Los Angeles, San Diego, and throughout Southern California stem from drivers who fail to check blind spots. Because motorcycles are smaller and more maneuverable, they’re often missed in a driver’s mirrors—especially when changing lanes on the freeway.

Strategic legal move: Our firm regularly works with accident reconstructionists and traffic experts to show exactly where the driver failed to observe the rider. It's this type of strategy that helps us hold insurers accountable.

3. Speeding

Speed kills—especially when it comes to motorcycles. Both speeding drivers and speeding riders are at risk of severe crashes. The faster the speed, the less time a driver has to react, and the more serious the injuries in a crash.

Injury impact: Motorcycle crashes at high speeds often lead to traumatic brain injuries, spinal cord damage, and multiple fractures.

What we do: We pull black-box data, subpoena traffic reports, and break down frame-by-frame video evidence to prove liability and maximize compensation.

4. Left-Turn Accidents

One of the most common motorcycle crash scenarios is when a car turns left in front of an oncoming rider. These collisions are frequently fatal or life-altering. Most occur because the driver misjudged the motorcycle’s speed—or didn’t see it at all.

Insurance loopholes: Insurance companies often try to argue that the motorcyclist was speeding, even when it wasn’t the case. Dr. Keshavarz knows their playbook and counters it strategically—using physics, not speculation.

5. Doorings

This is when a driver or passenger opens a car door into the path of an oncoming motorcycle. It usually happens on tight city streets like those in downtown San Diego, Santa Monica, or Long Beach.

Real-world risks: Doorings can launch riders into traffic or onto the pavement without warning.

Legal strategy tip: Many riders don’t know that a doored rider can sue the vehicle’s occupant for negligence. We file aggressive claims against inattentive door-openers and their insurers.

6. Lane Splitting Gone Wrong

Lane splitting (riding between slow-moving traffic) is legal in California—but still highly controversial. While it allows bikers to avoid gridlock, it also puts them in a tight space between unpredictable drivers.

Who’s at fault? This is where it gets tricky. Drivers often swerve or open doors without warning. Even though lane splitting is legal, insurance companies will often try to shift blame.

AK’s edge: We frame these incidents from a legality standpoint and demonstrate how the rider was operating within their rights. Dr. Keshavarz combines legal precision with a medical understanding of trauma that makes our arguments hit harder.

7. Impaired Driving

Whether it’s alcohol, marijuana, or prescription drugs, impaired drivers are a major threat to bikers. Their reaction time is slower, their judgment is off, and their lane control is often poor. Motorcycles, being harder to spot and less forgiving in collisions, often take the brunt of these drivers' poor choices.

Injury lawyer insight: DUI crashes involving motorcycles often have a criminal and civil component. We use the criminal evidence (police reports, toxicology results) to fortify your civil case.

8. Poor Road Conditions

Potholes, uneven pavement, loose gravel, and construction zones can be a nuisance for cars—but deadly for motorcycles. A small road imperfection can cause a rider to lose control instantly.

Who’s liable? Sometimes it’s the city, the state, or a private contractor. These are tough cases, but we’re not afraid of them. Filing against a government agency has strict timelines and legal barriers—but we know how to navigate them.

9. Defective Bike Parts or Gear

Sometimes, the crash wasn’t caused by a driver—but by a mechanical failure. Faulty brakes, defective tires, or poorly manufactured helmets can result in serious injury or death.

Tactic we use: We bring in product liability experts and go after manufacturers, suppliers, and anyone else in the distribution chain. If the gear was faulty, someone will be held accountable.

10. Inexperience or Reckless Riding

Not all motorcycle crashes are caused by other drivers. In some cases, new riders or those who take unnecessary risks—speeding, wheelies, or unsafe passes—may cause their own injuries.

But here's the twist: Sometimes these riders are injured by other drivers who made the situation worse. Even if a rider made a small mistake, California's comparative fault laws may still allow them to recover compensation.

Dr. Keshavarz’s approach: She never lets an insurance company fully blame the rider without dissecting the entire event. She finds the gaps in their story—and uses them to shift the narrative.
