Liability Issues in Motorcycle Accidents: Who’s Responsible in San Diego?

Motorcycle accidents in San Diego can be complex when it comes to determining who is legally responsible. Unlike car accidents, where fault is often straightforward, motorcycle crashes involve multiple factors, including negligent drivers, defective motorcycle parts, and dangerous road conditions.

If you were injured in a motorcycle accident, understanding liability laws can help you pursue the compensation you deserve. At Hulburt Law, our experienced San Diego motorcycle accident attorneys fight for injured riders, ensuring that the right parties are held accountable.

Here’s what you need to know about liability in motorcycle accident cases in San Diego.

‍

1. Driver Liability: When Another Motorist Is at Fault

What is Driver Negligence?

Negligence is the failure to use reasonable care to prevent harm to others. A person is negligent if they do something that a reasonably careful person would not do in the same situation. (Judicial Council of California Civil Jury Instructions No. 401.)

How to Prove Driver Liability

To establish driver negligence, you must prove the following:

1. That the driver was negligent.
2. That you were harmed.
3. That the driver’s negligence was a substantial factor in causing your harm.

(Judicial Council of California Civil Jury Instructions No. 400.)

How Drivers Cause Motorcycle Accidents

Most motorcycle crashes happen because another driver was careless or reckless. Common examples of driver negligence include:

• Distracted Driving – Texting, using a phone, or eating while driving.
• Failure to Yield – Turning left in front of a motorcycle or failing to stop at an intersection.
• Unsafe Lane Changes – Merging without checking blind spots.
• Tailgating & Speeding – Rear-ending a motorcycle or reckless driving.
• Driving Under the Influence (DUI) – Alcohol and drugs slow reaction times and impair judgment.

Evidence of Driver Negligence

Your attorney will gather evidence, such as:

• Police reports – If the other driver was cited for a traffic violation.
• Accident scene photos – Showing skid marks, vehicle damage, and road conditions.
• Eyewitness statements – Testimony from bystanders or passengers.
• Traffic camera or dashcam footage – Video proof of the accident.
• Phone records – To show if the driver was texting or on a call.
• Expert opinions – Accident reconstructionists and human factors experts can assist in proving fault.

In most cases, the negligent driver’s insurance company is responsible for paying compensation. If they refuse to offer a fair settlement, you may need to file a lawsuit.

2. Manufacturer Liability: When a Defective Motorcycle Causes an Accident

Not all motorcycle crashes are caused by negligent drivers—some result from defective motorcycles or faulty parts. If a manufacturing defect contributed to your accident, the motorcycle company may be held strictly liable.

Examples of Defective Motorcycle Parts:

• Brake Failure – Defective brake pads, rotors, or hydraulic systems.
• Tire Blowouts – Faulty or poorly manufactured tires.
• Throttle Malfunctions – Sudden acceleration or failure to respond.
• Fuel System Defects – Leaks that cause fires or explosions.
• Faulty Steering Components – Loss of control due to defective handlebars or suspensions.

How to Prove Manufacturer Liability

To win a product liability case, your attorney must prove:

1. The motorcycle or part had a defect that made it dangerous.
2. The defect caused the accident.
3. You were using the motorcycle as intended at the time of the crash.

(Judicial Council of California Civil Jury Instructions No. 1200, 1201, 1245.)

A motorcycle accident attorney can work with engineers and safety experts to examine the bike and identify defects. If a manufacturer is found liable, you may be able to recover compensation through a lawsuit against the company.

3. Government Liability: When Poor Road Conditions Cause an Accident

Sometimes, dangerous road conditions play a role in motorcycle accidents. Unlike cars, motorcycles are more vulnerable to potholes, loose gravel, and uneven pavement. If a poorly maintained road caused your accident, the government agency responsible for road upkeep could be held liable.

Examples of Hazardous Road Conditions:

• Potholes & Cracks – Can cause a motorcycle to lose balance.
• Loose Gravel or Debris – Especially dangerous in turns or at high speeds.
• Lack of Proper Signage – Hidden intersections or sharp curves.
• Poorly Marked Construction Zones – Sudden lane shifts or obstructions.
• Malfunctioning Traffic Lights – Can cause dangerous intersection crashes.

Suing a Government Entity in California

If your crash was caused by a dangerous road condition, you may be able to file a claim against the City of San Diego, Caltrans, or another government agency. However, government claims have strict deadlines—you must file a notice of claim within six months of the accident.

4. Comparative Fault: What Happens If You Were Partially at Fault?

California’s Comparative Fault Law (Pure Comparative Negligence)

California follows a pure comparative negligence rule. This means that even if you were partially at fault for the accident, you can still recover compensation—but your total award will be reduced by your percentage of fault.

Example:

If a court finds that:

• You were 20% at fault (for slightly speeding), and
• The other driver was 80% at fault (for running a red light),
• You can still recover 80% of your total damages.

How Insurance Companies Use Comparative Fault Against Motorcyclists

Insurance companies often try to blame motorcyclists for their own injuries by arguing that:

• You were lane-splitting unsafely.
• You were speeding or weaving through traffic.
• You weren’t wearing proper gear.

An experienced motorcycle accident lawyer will fight back against these tactics and ensure that you aren’t unfairly blamed for an accident that wasn’t your fault.

‍

5. What Happens If the At-Fault Driver Is Uninsured or Underinsured?

Unfortunately, many drivers in California are uninsured or carry only the minimum required coverage. If you were hit by an uninsured or underinsured driver, you may still have options for compensation:

Your Legal Options:

• Uninsured/Underinsured Motorist (UM/UIM) Coverage – If you have UM/UIM insurance, your own policy can cover medical expenses and damages.
• Personal Injury Lawsuit – You may sue the at-fault driver personally, but collecting compensation can be difficult if they have no assets.
• Third-Party Liability – If a defective vehicle or hazardous road conditions played a role, other parties may be responsible.

Your attorney will explore every possible avenue to ensure you receive the compensation you need.
