Truck Blind Spots: Know the Danger Zones

Know The No Zones Regarding Truck Blind Spots

You’re traveling down the highway and come across a semi truck. You become nervous, as you realize that there are blind spots around a large vehicle. And thus, you feel like David going against Goliath on the road.

Your fears are not completely unfounded. Research shows that more than 4,000 individuals passed away in 2018 due to crashes involving semi trucks. 

Many of these types of accidents happen simply because people who share the road with semi trucks don’t mind truck blind spots. Fortunately, we’ve compiled a guide with vital information on passing trucks and how to avoid blind spots.

Let’s get started!

What Are Truck Blind Spots?

Truck blind spots are the areas around a semi truck where the truck driver’s vision is either gone or restricted. The driver cannot see these areas when they look through a side or rear-view mirror.

Blind spots are the result of a semi truck’s sheer length and height. Because semi trucks are big, their drivers cannot see certain parts near their vehicles and the roadway.

In addition, the windshield and the size and design of the dashboard contribute to blind spots.

You won’t always be able to avoid entering a semi truck’s blind spot. However, it is critical that you avoid staying in these spots to avoid possible hazards.

If you don’t, the truck might switch to your lane and run into you. And in many cases, truck accidents that result from blind spots cause people in passenger cars to die more than they cause the truck drivers to die.

How to Avoid Semi Trucks’ Blind Spots

The smartest move you can make to avoid a semi truck accident is to avoid its blind spot, also known as its “no-zones.” There are several types of these zones.

First, you have no-zone in the front. This zone covers the lengths of 20 cars in the front area of the cab. Truck drivers sit much higher than other vehicle drivers do, and this causes them from being able to see the cars right in front of them.

Second, you have the no-zone on the right side. This area is behind the truck’s cab on the right. Because this is such a huge blind spot, you should allow one car length or more from the truck’s back area when you’re driving on a highway with multiple lanes.

Third, you have the no-zone on the left side, which is behind the truck’s cab on the left. This area is around 50% of the right no-zone’s size. As with the no-zone on the right side, allow one car length or more from the truck’s back area.

Finally, you have the no-zone on the back side of the truck. Truck cabs don’t have rear-view mirrors, so truck drivers can’t see if people are tailgating behind them. If they must stop immediately, tailgaters can easily rear-end them and suffer injuries or death as a result.

So, remember that when you are driving behind a semi truck, if you follow the truck too closely, you put the driver in control of the decisions you make as a driver. For instance, when he brakes, you must do the same. If you back off, you’ll regain control of your decision-making as a motorist. 

All in all, a good rule of thumb to remember is that when you can’t see the face of a semi truck driver through your rear-view or side mirror, that driver can’t see you, either. So, move into a position where they can see you as quickly as possible. 

Avoid Blind Spots Around a Large Vehicle While Passing Trucks

If you’re trying to pass on the right or left of a semi truck, you should try not to remain in the truck’s no-zone area on either side.

Also, if you must pass in front of the truck, make sure that you have enough time to pass the front-area no-zone prior to getting ahead of the semi truck. 

Giving Trucks Turning Room

Semi truck drivers can’t help but to make turns that are very wide. So, when you notice that a semi truck’s blinker is on, avoid pulling up beside them.

The reality is, the truck will take just a handful of seconds to make the turn. Then, once they do, you can enjoy cruising at your pre-turn speed once again.

Avoiding Truck Blind Spots

You can minimize possible incidents with semi trucks by taking a few steps.

First, position your rear-view mirror so that the mirror covers your back vision. In addition, adjust the mirror on your left side so that you can partially see your car’s left side. Do the same right your mirror on your right side.

You should take these steps each time you get a new vehicle, or occasionally in your current vehicle.
