If you’ve driven on the road with large trucks before, you may have come across the term “no zone” before. This term came from government safety campaigns in the 1990s, trying to help people avoid getting caught in a truck’s blind spots. The Department of Transportation started using “No Zone” in their messaging to show where it’s hardest for truck drivers to see other vehicles, hoping it would lower accidents through awareness, not just more laws. 

A truck’s “No Zone” is basically its blind spot, but much bigger than what you might be used to in a regular car or SUV.  One reason these blind spots are so large is because of the driver’s position. Truck drivers sit much higher off the ground and need to rely a lot on their mirrors to keep track of traffic nearby.  Knowing about these areas when driving near trucks can help you stay safe and avoid a serious crash.

Where Are a Truck’s No Zones Located?

Understanding where a truck’s largest blind spots are makes the road safer for everyone. The following areas are the “No Zones” you need to be most aware of when driving near commercial trucks.

The Right-Side Blind Spot

This is the biggest and most dangerous blind spot on a commercial truck. The right-side No Zone runs along the entire length of the truck and the trailer and often stretches across several traffic lanes. Truck drivers have the toughest time seeing vehicles here. That’s why passing a truck on the right can be extremely risky. 

The Left-Side Blind Spot

While not as large as the right side, the left-side blind spot is still there, especially around the length of the cab and sleeper area. It’s generally a good idea not to spend too much time in this area next to a truck, just in case they aren’t able to see you and decide to switch lanes. 

The Rear Blind Spot

The space just behind a truck’s trailer is completely out of a truck driver’s view. If you’re following closely, you’re almost invisible to the driver. Tailgating trucks in this No Zone is especially dangerous and can cause serious rear-end collisions. 

The Front Blind Spot

The front No Zone is the section of road right in front of the cab. Truck drivers can’t see vehicles that are too close to their bumper. If you cut in front of a truck and then have to stop suddenly, you’re putting yourself in danger. Trucks need far more time and distance to come to a safe stop compared to a car.

Can a Truck Driver Be at Fault in a No Zone Crash?

Just because a crash happens in a truck’s “No Zone” does not mean the truck driver is automatically off the hook. Truck drivers have a duty to share the road safely. Blind spots do not excuse careless or reckless driving decisions.

Even with No Zones, truck drivers must: 

• Regularly check their mirrors
• Signal well before switching lanes or turning
• Carefully ensure it’s safe before making any lane changes or turns
• Follow all Federal Motor Carrier Safety Administration (FMCSA) safety regulations related to large commercial vehicles 

A truck driver could still be at fault if they get distracted by their phone, drive while fatigued,  speed, or move into another lane without noticing a car beside them. These mistakes all show careless behavior behind the wheel, whether a truck’s No Zone is involved or not.
