Motorcycle riders tend to suffer from more severe injuries in road accidents than other road users. According to the National Highway Traffic Safety Administration, 6,335 motorcyclists in the United States died from road crashes in 2023. The fatality rate among motorcyclists was almost 28 times higher than that among car occupants.
According to careless driving injury lawyer Luis P. Guerra, grave accidents can occur when car and truck drivers fail to operate their vehicles in a careful manner. In some cases, motorcycle injuries are attributed to lane-splitting.
In the event that you have sustained injuries after lane splitting and a collision resulted from a driver’s careless lane change maneuver, the major question you might be asking yourself is whether you are entitled to a legal claim. The answer really depends on where the accident happened, how the whole collision played out, and if the other driver’s negligence actually helped cause the wreck.
Reckless driving leads to lane-splitting accidents. This kind of thing isn’t really up for debate. Motorcycle accidents will often occur if a driver is reckless and distracted. Some crashes happen if a driver fails to check their blind spots correctly before making a maneuver or when the riders who are engaged in lane splitting do not observe proper distance.
Let’s discuss how careless driving increases the likelihood of a lane-splitting accident.
Lane Splitting vs. Lane Filtering: The Legal Distinction That Matters
The terms ‘lane splitting’ and ‘lane filtering’ are not synonyms. The distinction between them affects how fault is identified. Lane splitting refers to the act of riding between lanes of moving traffic. Lane filtering, on the other hand, happens when motorcycles move between lanes of stopped or very slow traffic. Lane filtering is usually observed at intersections or when there’s gridlock.
States treat these acts differently. For instance, California lane-splitting laws permit this practice within reason. It is the responsibility of all motorbike riders in California to exercise prudence before performing this risky act. The states of Arizona, Utah, Montana, Colorado, and Minnesota allow lane filtering but only under restricted conditions.
In every other state, both practices are illegal. This fact matters for liability since a motorcyclist splitting lanes where it’s prohibited may end up partially or even fully at fault for the accident. In jurisdictions that adhere to the principle of comparative negligence, the damages are awarded based on the extent of fault or responsibility of each of the parties. Some states go further, and in instances where the motorist is found to be more than 50% at fault, any compensation owed to them is forfeited.
How Careless Driving Creates the Conditions for a Crash
When a vehicle driver does not actively check their mirrors and perform a blind spot check prior to changing lanes, there is a possibility of motorcycles penetrating the queues of static vehicles, going unnoticed until a crash occurs.
The following behaviors are responsible for most crashes:
- Change of lanes without the use of proper signal
- Looking at a phone instead of mirrors during slow-moving traffic
- Creeping forward without any actual looking when the lanes start to move
- Swinging a door into the roadway without checking for riders already coming through
- Doing abrupt merges near intersections or highway exits
All of these actions can count as negligence under standard traffic law. The fact that a motorcycle was lane splitting doesn’t just wipe out the other driver’s duty of care. There are cases where both sides can share fault, and in states where lane splitting is allowed, the shared-liability review tends to apply in a straightforward way.
The Fault Question When Lane Splitting Is Illegal
In states where lane splitting is prohibited, injured motorcyclists face an uphill claim. Investigators and insurance adjusters often stereotype the rider’s illegal conduct as the main cause of blame. Still, no single rider maneuver can be said to be the only cause of an accident.
A driver should not engage in texting during merging. They should use turn signals before switching lanes and check the side or rear blind spots. Otherwise, this will be deemed negligent, irrespective of where the motorcycle was positioned.
If the negligence was a main cause of the accident, the driver is at fault. How much liability depends on the specific facts and the state’s comparative fault framework. A personal injury attorney can evaluate the evidence to determine whether the other driver’s conduct supports a viable claim.
What Evidence Shapes the Liability Determination
Driver Behavior
Determining liability in a motorcycle accident depends to a significant extent on whether the other was negligent and failed to use a signal. or made some other traffic violation. The evidence collected should show the behavior of the driver before the crash. Witness statements, dashcam footage, and vehicle black box data can each be used to show the driver’s actions leading up to the crash.
Rider Conduct
The motorcyclist’s conduct is also relevant, including their speed compared to traffic flow, their lane placement, and what they were doing at that moment. A rider who moves at a reasonable speed, doesn’t weave, and is positioned in a predictable manner within the lane gap tends to be in better evidentiary standing than someone speeding up unpredictably or squeezing past near a live intersection. The rider’s behavior pattern is more important compared to a single instance of exhibited behavior.
Road and Visibility Conditions
Lighting, traffic density, lane width, and road markings kind of change how foreseeable the contact was. According to the National Highway Traffic Safety Administration (NHTSA), motorcycles are more likely to be involved in vehicle collisions when the other vehicle fails to yield the right of way. Lane-splitting incidents involving motorcycles have also shown this result.
The Juror Bias Problem
There is a documented tendency, in motorcycle accident litigation, for jurors to hand out partial blame to the riders, based on the idea that riding is just inherently risky. A research study found that focus group participants assigned shared liability to motorcycle riders even before any evidence was shown. The bias stems from the mode of transportation used in the incident.
Even with this bias, a claim is not automatically destined to fail, but the quality of the evidence and the overall legal preparation matter a lot more in motorcycle cases than in more standard vehicle collisions. Photos of the crash scene, independent witness statements, and any data that shows how the other driver was acting before the impact happened can directly push back against assumptions about rider recklessness.
Understanding Your Options After a Lane Splitting Accident
Careless driving is a recognized cause of lane-splitting accidents, and the fact that a motorcyclist was doing the whole split between lanes doesn’t automatically shift all responsibility over to the rider. Instead of focusing solely on the area in which the motorcycle was located, a fault analysis particularly breaks down the conduct of each of the parties.
In most cases, the evidentiary strength comes from proving the driver at fault, such as unsafe lane change behaviors, distracted driving, and failure to see the blind spot.
If you got injured in this kind of collision, you should really preserve evidence quickly. This means keeping copies of photos, witness contact information, and your medical records. This action helps an individual fight off any disputes in the future.
NHTSA’s motorcycle safety data shows that driver behavior, not rider presence, is what drives most multi-vehicle motorcycle crashes.
