You’re driving through Los Angeles traffic when a car suddenly swerves into your lane, forcing you to brake hard or swerve.
Seconds later, you’re in a crash — and you’re left wondering not only how this happened, but also whether cutting someone off while driving is even legal and who pays for your injuries.
If you’re asking yourself, “Is cutting someone off illegal?”, you’re not alone. Many crash victims feel confused and angry after a careless driver cuts them off and causes a wreck.
This guide explains what cutting someone off while driving is, how California law treats this dangerous behavior, and what your legal options are when a cut-off driver causes an accident in Los Angeles.
Understanding Your Legal Rights After a Cut-Off Driver Crash in Los Angeles
When a driver abruptly cuts you off and causes a collision, you may have the right to seek compensation for medical bills, lost wages, pain and suffering, and more.
In California, drivers must use reasonable care on the road. That includes changing lanes safely, signaling in time, and leaving enough distance to avoid a crash. When a driver fails to do that,cutting someone off while driving can become negligence, and negligent drivers can be held financially responsible.
Aknowledgeable car accident lawyer can help you determine whether the other driver’s actions were illegal, how they violated traffic laws, and what evidence you need to prove your case.
What Is Cutting Someone Off while Driving?
Before you can prove fault, it helps to understandwhat cuts someone off,from a legal and practical standpoint.
In everyday language, cutting someone off usually means:
- Abruptly changing lanes directly in front of another vehicle
- Leaving too little space for the other car to slow down safely
- Diving into a lane without signaling or checking blind spots
- Turning in front of an oncoming vehicle at an intersection
If the other driver’s maneuver forces you to brake hard, swerve, or collide, that’s a classic example ofcutting someone off while driving.
Even if the driver insists they “didn’t see you,” that doesn’t excuse their duty to check mirrors, signal, and make sure the lane is clear before moving over.
Is Cutting Someone Off Illegal in California?

So,is cutting someone off illegal under California law?
There’s no single statute that uses the phrase “cutting someone off,” but several traffic laws make this behavior illegal when it’s unsafe. Two of the most important are:
- California Vehicle Code § 22107, which prohibits turning or moving right or left on a roadway unless it can be done with reasonable safety and, when other vehicles may be affected, only after giving an appropriate signal.
- California Vehicle Code § 21658, which requires drivers to stay in a single lane as nearly as practical and not move from that lane until the movement can be made with reasonable safety.
When a driver suddenly swerves into your lane or merges without enough space, that kind ofcutting someone off driving is often anunsafe lane change under § 22107 or a violation of the single-lane rule in § 21658.
If a driver’s lane change or turn is done without proper care and causes a crash, police may cite them, and that citation can support your civil injury claim.
In other words,is cutting someone off illegal when it creates an unreasonable risk and leads to a collision? Yes — it can constitute apparent negligence and a violation of California traffic law.
Common Ways Drivers Cut Someone Off in Los Angeles Traffic
Los Angeles traffic creates countless opportunities for dangerous cut-offs. You’ve probably seen drivers:
- Weaving across multiple lanes to avoid congestion
- Jumping in front of other cars to exit at the last second
- Speeding up to merge and cutting off slower traffic
- Making left turns across traffic without enough time.
- Cutting off motorcyclists who are harder to see
These behaviors often come with other risky actions, such as:
- Tailgating
- Distracted driving (texting, scrolling, GPS)
- Road rage or aggressive driving
- Driving under the influence
Whencutting someone off, driving with these factors combined increases the likelihood of a crash — and serious injuries — dramatically.
Injuries Commonly Caused When a Driver Cuts You Off
Even if the collision seems “minor,” being cut off can cause serious injuries, especially at freeway speeds. Common injuries include:
- Whiplash and other neck injuries
- Back and spinal injuries
- Concussions and traumatic brain injuries
- Broken bones in the arms, legs, or ribs
- Soft-tissue injuries to the shoulders, hips, and knees
- Emotional trauma, anxiety, or PTSD
These injuries may require:
- ER visits and diagnostic tests
- Physical therapy or chiropractic care
- Pain management and medications
- Time off work and reduced income
When a cut-off driver causes this kind of harm, you should not have to shoulder the financial burden by yourself.
Who Is at Fault When Someone Cuts You Off?
Fault in a cut-off crash often depends on what each driver was doing in the moments leading up to the collision. Still, in many cases, the driver who executed the unsafe lane change or turn will bear most — or all — of the blame.
Evidence that can help prove fault includes:
- Police reports and any citations issued
- Dashcam or traffic camera footage
- Witness statements from other drivers or pedestrians
- Photos of vehicle damage and skid marks
- Data from onboard vehicle systems
A skilled car accident lawyer can analyze this evidence and show that the other driver’scutting-off maneuver violated their duty of care and relevant statutes, such as Vehicle Code §§ 22107 and 21658.
Comparative Negligence: What If They Say You’re Partly at Fault?

Insurance companies often try to argue that you share blame for the crash. They might say you were speeding, following too closely, or not paying attention.
Under California’s comparative negligence rules, your compensation can be reduced by your percentage of fault, but it is not eliminated.
For example:
- If your damages are valued at $100,000
- And you’re found 20% at fault for following too closely.
- You could still recover $80,000
Even if the insurer claims you are partially responsible, that does not erase the other driver’s responsibility forcutting someone off while driving in an unsafe way. An experienced attorney can challenge unfair blame and push for a more accurate allocation of fault.
What Compensation Can You Seek After a Cut-Off Crash?
After a crash caused by a cut-off driver, you may be able to seek compensation for:
- Medical bills (past and future)
- Physical therapy and rehabilitation
- Lost wages and loss of future earning capacity
- Property damage and vehicle repairs
- Pain and suffering
- Emotional distress and reduced quality of life
If the driver’s behavior was especially reckless — for example, road rage or drunk driving — your case may involve a higher settlement value due to the seriousness of their misconduct.
LA Injury Lawyers can work with medical experts, vocational specialists, and economists to calculate the full extent of your losses so you don’t settle for less than your case is worth.
How Long Do You Have to File a Claim After a Cut-Off Accident?
Most California car accident claims are governed by the personal injury statute of limitations in California Code of Civil Procedure § 335.1.
This law generally gives youtwo years from the date of the injury to file a lawsuit for injuries caused by the wrongful act or neglect of another person.
If you miss this deadline, you may lose your right to pursue compensation in court.
Shorter deadlines can apply when you are making a claim against a government entity (such as a city bus or government vehicle), so it’s essential to speak withLA Injury Lawyers as soon as possible after the crash.
How a Car Accident Lawyer Proves a Cut-Off Driver Was Negligent
Building a strong case against a cut-off driver requires more than just saying, “They cut me off.”
Your attorney may:
- Obtain and analyze the police report
- Request and review traffic camera or dashcam footage
- Subpoena cell phone records if distracted driving is suspected
- Work with accident reconstruction experts
- Gather medical records and expert testimony about your injuries.
By connecting the dots betweenwhat is cutting someone off while driving, specific traffic violations underVehicle Code § 22107 (unsafe lane changes) andVehicle Code § 21658 (failure to stay in a single lane), your lawyer can show that the other driver acted unreasonably and should be held liable.

FAQs About Cut-Off Driver Accidents in Los Angeles
What is cutting someone off while driving?
It’s when a driver abruptly moves into your lane or turns in front of you without enough space, forcing you to brake or swerve to avoid a collision.
Legally, it often involves unsafe lane changes and failing to stay within a single lane, both of which can violateVehicle Code §§ 22107 and 21658.
Is cutting someone off illegal if no crash happens?
Many people ask whether cutting someone off is illegal if there’s no accident.
Even without a crash, unsafe lane changes and lane straddling can still violate the California Vehicle Code and result in citations. But in an injury case, it’s the combination of illegal behavior and resulting harm that creates a strong compensation claim.
What if the other driver says I rear-ended them, so it’s my fault?
Rear-end crashes are often blamed on the trailing driver, but that’s not always fair.
If you rear-ended someone because theycut you off abruptly and left no room to stop, that can shift much of the blame back to them. Evidence like skid marks, witness statements, and video can be critical.
Do I really need a lawyer for a cut-off crash?
Technically, you can handle a claim yourself, but the insurance company will likely minimize your injuries or argue thatcutting someone off while driving wasn’t the real cause.
ALos Angeles car accident lawyer can level the playing field, gather evidence, and negotiate for a settlement that reflects your actual losses.
How long do I have to file a claim?
In many California car accident cases, you generally have two years from the date of the crash to file a personal injury lawsuit underCode of Civil Procedure § 335.1.
Claims involving government vehicles or dangerous road conditions can have shorter deadlines, so it’s smart to contactLA Injury Lawyers as soon as possible.
