The most common causes of motorcycle accidents are human factors

These top causes of motorcycle accidents result from human error, poor judgment, and careless driving. In addition to driver behavior, vehicle characteristics, and roadway design can also contribute to a crash.

How Fault Is Determined in California Motorcycle Accidents

Fault in California motorcycle accidents is determined by negligence. California law requires every person, company, or organization to act reasonably. When someone acts negligently in a way that hurts someone else, the negligent party is legally at fault. Fault can be the basis of a compensation claim.

The main questions for evaluating fault for a motorcycle accident in California are:

Whose actions caused the accident?

Were those actions reasonable, or unreasonable?

Did the person’s unreasonable actions result in the victim’s injuries?

A person can be unreasonable because of something that they do, like changing lanes when it’s not safe. A person can also be unreasonable by failing to do something, such as not reducing their speed in inclement weather.

Motorcycle accidents are evaluated on a case-by-case basis

Each motorcycle accident claim is evaluated individually to determine fault.

One person may be at fault for a motorcycle accident, or multiple people may be at fault.
The party responsible may be a vehicle driver, a vehicle manufacturer, a government entity that manages the roads, or someone else entirely.
A person, corporation, organization, or government entity may be responsible for a motorcycle accident.
Often, fault is based on a moving violation, but a moving violation is not required to be at fault.
California’s pure comparative fault applies in San Bernardino motorcycle accident claims.

A victim must prove fault to claim compensation.

The Role of Expert Witnesses in Your Motorcycle Case

Expert witnesses may play an important role in a motorcycle accident claim.

An expert witness can explain the pain and suffering that the victim has endured from their injuries. An expert can describe the extent of permanent impairment. They may discuss the financial impact of injuries.

There are many types of expert witnesses. A lawyer can help you determine which experts may benefit your case. They can prepare expert witnesses for your case.

Documenting Your Injuries: What Your Attorney Will Need

When you meet with your attorney, bring all the documentation you have. Your attorney will need a copy of the accident report and your medical records. They will need your income information. A list of witnesses can give your attorney a starting point to build your case. Your attorney can explain how to journal your recovery to build evidence of pain and suffering and other non-economic damages.

Why You Shouldn’t Wait To Hire an Attorney After a Motorcycle Crash

When you’re hurt in a motorcycle accident, you need to focus on healing. That’s hard to do when you’re navigating a legal claim by yourself.

An attorney can gather evidence when it’s most available, immediately after the accident. They know what to ask witnesses. They can identify things that may be important later in the case. Addressing these issues early can save time during your case. It can also maximize your compensation by building the evidence for your claim.
