Semi-trucks and tractor-trailers are some of the biggest vehicles on the road. Because of their size, they have large blind spots that make it hard for truck drivers to see cars around them. These blind spots can lead to serious crashes if drivers aren’t careful.

If you’ve ever driven near a semi-truck and felt nervous, you’re not alone. Knowing where these blind spots are and how to avoid them can help keep you and others safe.

What Are Blind Spots on Semi-Trucks?

Blind spots are areas around a vehicle that a driver can’t see through mirrors. While all vehicles have blind spots, semi-trucks have much larger ones. Because these trucks sit higher up and don’t have rearview mirrors like regular cars, they rely only on side mirrors. This creates areas where cars and motorcycles can completely disappear from the truck driver’s view.

These areas are often called “No-Zones.” If you’re driving in one of these spots, the truck driver might not even know you’re there.

Why Semi-Truck Blind Spots Are So Dangerous

The size of a truck’s blind spot makes accidents more likely. Even if a trucker checks their mirrors, they may still miss smaller vehicles in these areas. When a truck changes lanes, turns, or slows down, a car in a blind spot can get hit.

Truck drivers also need more time and space to stop. If they don’t know a car is too close, they might not slow down in time. This can lead to rear-end collisions or sideswipes.

The 4 Main Blind Spots Around a Semi-Truck

Understanding where a truck’s blind spots are can help you stay out of them. There are four main areas to watch for:

1. In Front of the Truck

The front blind spot is about 20 feet long. If you’re too close in front of the truck, the driver might not see your car. This can be dangerous if you have to stop suddenly. Try to keep a safe distance when you’re in front of a semi-truck.

2. Behind the Truck

The rear blind spot is even larger—up to 200 feet long. Because trucks don’t have rearview mirrors, they can’t see what’s directly behind them. Tailgating a truck puts you in a blind spot and gives you no time to react if the truck stops. It’s better to follow at a safe distance so you’re always visible.

3. Driver’s Side (Left Side)

This blind spot runs along the left side of the truck. While it’s smaller than the right side, it still exists. If you’re driving right beside the truck on this side, especially near the cab or trailer, the driver might not see you.

4. Passenger’s Side (Right Side)

This is the largest blind spot and the most dangerous one. It starts near the front of the truck, goes past the passenger door, and stretches back several lanes at an angle. Drivers who stay in this area for too long can be at risk, especially if the truck turns right or changes lanes. Some crashes in this area are called “right hook” accidents, where a truck turns right and hits a car it didn’t see.

How to Avoid a Semi-Truck’s Blind Spots

You can lower your risk of getting into a truck accident by staying out of blind spots whenever possible. Here are a few tips:

• Stay visible: If you can’t see the truck driver’s face in the side mirror, they probably can’t see you.

• Don’t hang out beside a truck: Pass quickly and safely if you need to be next to a truck.

• Keep your distance: Leave at least 20 feet in front and 200 feet behind a truck.

• Use your signals: Let truck drivers know what you’re planning to do. Sudden lane changes can lead to crashes.

• Be patient: Trucks take longer to speed up, slow down, and turn. Give them the space they need.

What Truck Drivers Should Do to Prevent Blind Spot Accidents

Truck drivers also have a role in avoiding blind spot crashes. They should:

• Check mirrors often, especially before turning or switching lanes.

• Signal well in advance before making any moves.

• Follow speed limits and avoid tailgating.

• Avoid distractions like texting while driving.

• Take rest breaks so they don’t drive while tired, which is required by trucking laws.

Even with these steps, crashes can still happen. When they do, it’s important to figure out who is responsible.

Who’s Responsible in a Blind Spot Truck Accident?

In many cases, the truck driver may be at fault if they didn’t check mirrors or signal properly. But sometimes, other drivers may share blame if they were following too closely, cutting in too fast, or driving in a blind spot for too long.

Each crash is different. Investigators look at things like road conditions, traffic laws, and what each driver did before the accident. In some cases, trucking companies can be held responsible if they didn’t train their drivers well or failed to maintain the truck.

If you were hurt in a crash with a semi-truck, you might be dealing with injuries, bills, and questions about what to do next. Talking to a lawyer can help you understand your rights and what steps to take.
