If you regularly drive on the 101 or 405 freeways here in the San Fernando Valley, you’ve seen it happen countless times: a motorcyclist carefully rides between lanes of slow or stopped cars. This practice, called lane-splitting, is a daily reality of commuting in and around Encino. It’s also a source of constant confusion for both riders and drivers. While lane-splitting is legal in California, it raises a critical question when a collision occurs: who is at fault?
The answer isn’t always simple. Unlike a straightforward rear-end collision, determining liability in a lane-splitting accident involves a detailed look at everyone’s actions. Skilled California personal injury attorneys can help clear up the confusion and explain how the law handles these unique and often serious accidents.
Is Lane-Splitting Legal in California? A Clear Answer
Let’s start with the most basic question. Yes, lane-splitting is legal in California. Our state is currently the only one in the nation with a law explicitly permitting this practice. For many years, lane-splitting existed in a legal gray area. In 2017, Assembly Bill 51 was signed into law, officially adding Section 21658.1 to the California Vehicle Code.
This statute formally defines lane-splitting as riding between rows of stopped or slow-moving vehicles in the same lane. Motorcyclists are allowed to use this maneuver to navigate California’s notoriously congested traffic.
Safety Guidelines and the “Prudent and Reasonable” Standard
Just because lane-splitting is legal does not mean a motorcyclist can do it recklessly. The law requires riders to operate their motorcycle ” safely and prudently.” While the statute doesn’t define precisely what that means, the California Highway Patrol (CHP) has published safety guidelines to help riders and drivers understand what is generally reasonable.
These are not laws, but they are often used by insurance companies, judges, and juries to help determine fault. The guidelines suggest that lane-splitting is safer when:
- The motorcyclist’s speed is no more than 10 MPH faster than the surrounding traffic.
- The overall speed of traffic is 30 MPH or less.
- The rider considers the width of the lanes, the size of surrounding vehicles, and the current weather and road conditions.
A rider who ignores these guidelines and weaves through traffic at high speeds could be found to have acted negligently, even though lane-splitting itself is legal.
Determining Liability: California’s Comparative Negligence Rule
The most important concept for understanding liability in these cases is comparative negligence. In California, fault for an accident is not an all-or-nothing concept. Instead, a judge or jury will assign a percentage of responsibility to each party involved based on their actions.
Under this rule, you can still recover damages even if you were partially at fault for the accident. Your final compensation amount, however, will be reduced by your percentage of fault. For example, imagine a motorcyclist is injured in a lane-splitting accident, and the total damages are calculated at $100,000.
If the court determines the car driver was 80% at fault for making an unsafe lane change, but the motorcyclist was 20% at fault for going slightly too fast, the motorcyclist can recover $80,000 (the total damages minus their 20% of fault). This is where skilled personal injury lawyers can make a significant difference by presenting evidence to minimize their client’s share of liability.
Common Scenarios and How Fault Is Assessed
Let’s apply the idea of comparative negligence to a few common lane-splitting accidents.
A Car Changes Lanes Without Looking
This is one of the most frequent causes of these accidents. A driver, frustrated with traffic, abruptly changes lanes without checking their mirrors or blind spots and strikes a motorcyclist. In this scenario, the primary fault typically lies with the driver for violating the motorcyclist’s right of way. The driver must ensure a lane is clear before entering it. But if the motorcyclist was traveling at an unsafe speed, they could still be assigned a portion of the fault.
A Motorcyclist Is Speeding Excessively
If a motorcyclist is splitting lanes at 45 MPH while surrounding traffic is moving at 10 MPH, they are likely acting recklessly. Even if a car makes a sudden move, the motorcyclist’s excessive speed would be a major contributing factor to the collision, and they would likely bear a significant percentage of the liability. Experienced personal injury lawyers know that the motorcycle’s speed is often a central point of argument in these claims.
The Critical Role of Evidence in Your Case
Evidence is everything because these accidents depend on the specific details of what happened. The evidence collected can tell the story of the accident and help clear any doubt. If you are involved in a lane-splitting crash, gathering as much information as possible is vital.
This includes taking photos and videos of the scene, getting contact information from any witnesses, and obtaining a copy of the official police report. Dashcam or helmet camera footage can be compelling evidence. This information helps skilled personal injury lawyers reconstruct the accident and build the strongest possible argument to demonstrate the other party’s fault.
