A no zone is a blind spot around a large commercial truck large enough to completely hide your vehicle from the driver’s view. Every semi-truck, tractor-trailer, and large bus on the road has four of them, and driving inside one makes you invisible to the truck driver.
Sharing the road with an 80,000 pound truck already puts you at a disadvantage. When your vehicle disappears into a truck’s blind spot, that disadvantage becomes a serious threat. Truck drivers cannot react to a hazard they cannot see, and a sudden lane change, turn, or stop can end in a crash that leaves you facing life altering injuries, mounting medical bills, and a long road of physical recovery.
The problem is that most drivers have no idea how large these blind spots really are or how easily they can end up trapped inside one. Trucking companies rely on their drivers to manage these risks, but insurance adjusters often look for ways to shift blame onto the smaller vehicle after a crash occurs. Without a clear understanding of the No Zone and who is responsible for preventing these accidents, victims can be left fighting an uphill battle for the compensation they need.
In this article, you will discover what the No Zone is, where these blind spots are located, and how a trucking accident attorney can help you pursue accountability and full compensation after a crash.
Where Are a Semi Truck’s No Zones?
Every large commercial truck has four no zones, one in front, one behind, and one on each side. Knowing the size of each one tells you exactly where to position your car to stay visible.
Front No Zone
The front no zone extends roughly 20 feet directly ahead of the truck’s bumper. Truck cabs sit high off the ground, creating a blind spot directly in front that can swallow a passenger car completely. After you pass a truck, wait until you can see the full front of the truck in your rearview mirror before merging back into the lane.
Rear No Zone
The rear no zone stretches at least 30 feet behind the trailer. Tailgating a semi is a double mistake, the trucker cannot see you, and you lose all visibility of the road and traffic ahead of you.
Driver’s Side No Zone
The driver’s left-side blind spot begins at the mirror and extends one lane wide back to about the midpoint of the trailer. This is the smallest of the four no zones, which is why passing a truck on the left is always the safer choice.
Passenger Side No Zone
The passenger-side no zone is the largest and most dangerous of the four. It spans two full lanes of traffic and extends from the passenger-side mirror past the rear wheels of the trailer. Because the driver sits on the left, the entire right side of the truck is nearly invisible to them.
| No Zone Location | Approximate Size |
| Front | 20 feet ahead of the bumper |
| Rear | 30+ feet behind the trailer |
| Driver’s Side (Left) | One lane wide, mirror to trailer midpoint |
| Passenger’s Side (Right) | Two lanes wide, mirror past rear wheels |
Why Are Truck No Zones So Dangerous?
A fully loaded semi-truck can weigh up to 80,000 pounds. Passenger cars are much lighter than fully loaded semi-trucks. When those two collide, the smaller vehicle absorbs almost all of the force, and the people inside it pay the price.
Three factors make no zone crashes especially devastating:
- Size and weight mismatch: In a collision between a truck and a car, it is not a fair fight. The truck barely moves. Your vehicle crumples. Occupants of the smaller car face catastrophic, often fatal, injuries.
- Longer stopping distances: A loaded semi traveling at highway speeds needs nearly the length of a football field to come to a complete stop.
- Limited maneuverability: Trucks cannot swerve or brake sharply the way a car can. The trucker’s only tools are space and visibility, and a no zone strips both away.
When you drive in a no zone, you are taking away the one thing a truck driver needs to protect you: the ability to see you.
One pattern we consistently see in no-zone crashes on the Las Vegas Valley freeways is a trucking company arguing the car driver caused the crash simply by being in a blind spot, without addressing whether the truck driver checked that mirror before changing lanes. What we see across these claims is that the truck’s own lane-change and turn-signal data, pulled from the ELD, is usually what settles who actually failed to look.
What Is the Difference Between a Blind Spot and a No Zone?
Every vehicle has blind spots, areas that mirrors and windows do not fully cover. A no zone is a blind spot, but the scale is incomparable.
The FMCSA uses the term “no zone” specifically for commercial trucks because their blind spots are far larger and more dangerous than those on a standard passenger car. A truck’s passenger-side no zone can swallow two full traffic lanes at once. That is not a minor inconvenience, that is a serious hazard that causes catastrophic crashes every day across the country.
A tactic we see repeatedly from insurers in these cases is treating every no-zone collision as automatically the smaller vehicle’s fault. What we see across these claims is that dashcam footage showing the truck drifting into an occupied lane, rather than the car lingering in a blind spot, is what most often flips liability back onto the truck driver.
What Does Not Count as a No Zone?
Not every area near a truck is a no zone. If the driver has a clear, unobstructed view of your vehicle through their windshield or mirrors, you are not in one.
The simplest way to check is the mirror rule: if you can see the driver’s face in their side mirror, they can see you. If you cannot, assume you are invisible, and reposition your car until you are not.
“Ramzy was truly concerned from the first day that he saw our son. We felt he was going to be good for our son, the accident and the case. He always gave us good attention. He was always on top of anything we needed. He always gave us a hand and he never told us no. He always cared.” – Client, Las Vegas
How to Stay Out of Truck No Zones
Knowing where the no zones are is the starting point. What actually keeps you safe is how you drive around large trucks every single time you share the road with them.
Always Pass on the Left
The driver’s left side has the smallest blind spot, which makes it the safest side to pass. When you commit to passing, complete it quickly. Do not slow down or drift alongside the trailer, get through the no zone and keep moving.
Do Not Cut in Front of a Truck After Passing
After passing a semi, give it serious room before merging back in front. A fully loaded truck cannot stop quickly, even when the driver sees danger. Cutting in tight and tapping your brakes is one of the leading causes of rear-end truck collisions.
Signal Early and Hold a Steady Speed
Signal your lane changes earlier than you would around a regular car. Around trucks, drivers need more time and distance to respond to what you are doing. Sudden speed changes near a semi can pull you into a no zone without warning.
Watch for Wide Right Turns
Large trucks must swing left before completing a right turn, a maneuver called the “right turn squeeze.” If you are on the right side of a truck at an intersection, you may be heading directly into the path of the trailer as it swings back. Never try to squeeze between a turning truck and the curb, and stay alert for pedestrians who have the right of way at the intersection.
Merge Carefully Near Trucks on the Highway
Merging onto a highway can drop you directly into a truck’s passenger-side no zone before you realize it. Before you commit to a merge, confirm you can see the driver’s face in their mirror. If you cannot, adjust your speed until you can.
A few habits to build every time you drive near a large truck:
- Always pass on the left and do not linger next to the trailer
- Use the mirror test before merging or moving in front of a truck
- Give plenty of room before cutting back in after passing
- Never slip between a turning truck and a curb at an intersection
What to Do After a No Zone Truck Accident in Nevada
If a commercial truck hits you, the clock starts immediately. Trucking companies and their insurers have investigators and attorneys mobilizing before your car is even towed from the scene. Here is what you need to do right now.
Call 911 and Get Medical Care
Call 911 immediately, even if you feel fine. Serious truck accident injuries, internal bleeding, spinal damage, traumatic brain injuries, often do not show symptoms until hours or even days after the crash.
Document the Scene
If you are physically able, photograph everything: the position of the vehicles, the truck’s license plate, the DOT number on the trailer, the trucking company’s name, road conditions, and any debris or cargo on the road.
Preserve Truck Evidence Fast
Commercial trucks carry electronic logging devices (ELDs), onboard computers that record speed, location, and driving hours, as well as dashcam footage and driver logs. This evidence can prove exactly what the driver was doing before the crash. The problem is that trucking companies can legally overwrite or destroy this data within days unless your attorney sends an immediate preservation demand, called a spoliation letter, to stop it.
Do Not Give a Recorded Statement
An insurance adjuster will call you quickly, and they will sound reasonable and helpful. Do not give them a recorded statement before you speak with an attorney. Those calls are designed to get you to say something that contradicts your claim and reduces your payout.
Call Ladah Law
Before founding our firm, attorney Ramzy Ladah spent years on the other side of these cases, defending the insurance companies. He knows precisely how adjusters build a no-zone defense against injured drivers, and he has now spent his career defeating those exact tactics in court. We have recovered over $400 million for our clients, including a $10 million jury verdict in a trucking accident case. When you work with us, you get direct cell-phone access to your attorney, not a call center, and you pay nothing unless we win.
“I’m Gloria Evans and I had a personal injury accident. I was hoping to get reimbursed for some of it and went to an attorney who said she didn’t think she could handle the case but referred me to Ramzy. Ramzy took over and he and his staff did just a wonderful job. They got me more money than I thought that I would get. Everything was efficient. They kept me up to date on all the steps that we went through. And, I was just very pleased and would recommend them to anyone else.” – Gloria Evans

Frequently Asked Questions
How Far Behind a Semi Should I Drive to Stay Out of the Rear No Zone?
Maintain at least four seconds of following distance behind a semi on the highway, and increase that buffer on steep downhill grades or in wet weather.
Do Buses and Large RVs Have the Same No Zones as Semi-Trucks?
Yes, city buses, charter buses, and large recreational vehicles all have similar four-sided no zones, and the same mirror rule applies: if you cannot see the driver’s face, assume they cannot see you.
How Does Nevada Determine Fault When a Crash Happens in a No Zone?
Nevada uses a modified comparative negligence rule, meaning you can still recover compensation as long as you are found to be less than 51% responsible for the crash, even if you were partially at fault. The same framework governs how fault is divided in other Nevada crash cases.
Can a Truck Driver Be Held Liable Even if I Was in the No Zone?
Yes, commercial drivers are trained to monitor their blind spots before turning or changing lanes, and that legal duty of care does not disappear simply because you were in a no zone when the crash happened.
How Do I Know if the Truck Driver Saw Me Before the Crash?
If you could see the driver’s face in their side mirror before impact, there is a strong argument they could see you too, dashcam footage, ELD data, and eyewitness accounts can all help establish what the driver saw and when.
