Driving near large vehicles like Truck or HGVs requires extra awareness. These vehicles are significantly larger than passenger cars, and because of their size they have major blind spots where the driver cannot see other vehicles. Many road accidents involving Truck happen simply because drivers of smaller vehicles do not realise they are driving in one of these blind spots. Understanding how Truck blind spots work and how to drive safely around them can greatly reduce the risk of collisions and make the roads safer for everyone.
Why Truck Have Large Blind Spots
Unlike cars, most Truck do not have rear-view mirrors mounted on the windshield. Instead, drivers rely mainly on side mirrors to see the traffic around them.
This means the driver’s visibility depends heavily on mirror coverage. In poor weather conditions such as rain, fog, or snow, these mirrors can become blurred or less effective. When visibility drops, it becomes even harder for Truck drivers to spot smaller vehicles nearby.
Another factor is lighting. If a car is driving near a Truck in bad weather without its headlights on, it may become almost invisible to the truck driver.
What Are “No Zones”?
You may hear the term “No Zones.” These are the four large blind spots around a Truck where the driver has limited or no visibility.
These blind spots exist:
- In front of the truck
- Directly behind the trailer
- Along the left side
- Along the right side
When another vehicle is in one of these zones, the truck driver may not see it at all. Because of this, many truck-related crashes occur when smaller vehicles remain in these blind spots for too long.
The Largest Blind Spot: The Right Side
The right side blind spot is usually the largest area where a Truck driver cannot see nearby vehicles. This blind spot can extend up to three lanes out from the truck.
For this reason, passing a Truck on the right side can be extremely dangerous if you remain alongside the vehicle for too long. Drivers should always pass quickly and safely, avoiding lingering in the truck’s blind spot.
A good rule to remember is simple:
If you cannot see the truck driver’s face in their side mirror, they cannot see you.
Whenever possible, position your vehicle so the driver can clearly see you.
The Rear Blind Spot: Avoid Tailgating
Another dangerous area is directly behind the truck.
The rear blind spot behind a Truck can extend up to 200 feet, which is about two-thirds the length of a football field. If you are driving close behind a truck’s trailer, the driver likely cannot see you at all.
Tailgating trucks is risky for several reasons:
- The driver cannot see you
- Large trucks take longer to stop
- Debris or sudden braking could cause a serious accident
Always leave plenty of space between your car and the truck in front of you.
Drafting Behind Trucks Is Not Safe
Some drivers believe driving close behind a truck can save fuel because of reduced wind resistance. This practice, known as drafting, is both dangerous and often illegal.
Drafting reduces your reaction time and leaves you vulnerable if the truck brakes suddenly. It also places you in the truck’s rear blind spot, meaning the driver may not know you are there.
The safest option is always to maintain a safe following distance.
Snow Plows Have Similar Blind Spots
It’s not only Truck that have large blind spots. Snow plows operate with similar visibility limitations.
Even though they may be shorter than tractor-trailers, snow plows create hazards of their own. They push snow and slush that can pile up higher than your vehicle, and they often spread sand or salt behind them.
If you see a snow plow with its lights on and blade down, you should never attempt to pass it. Instead, allow it plenty of room to safely clear the road.
Trying to pass a working snow plow can quickly lead to dangerous situations and accidents.
The Role of Truck Driver Training
Professional Truck driver training plays a major role in improving road safety and reducing accidents caused by blind spots.
During HGV or LGV training, drivers learn how to manage large vehicles safely in traffic and how to monitor blind spots using mirrors and observation techniques. Training programmes also cover hazard awareness, defensive driving, and safe manoeuvring in busy environments.
Drivers are taught how to:
- Properly adjust and use mirrors
- Monitor blind spots continuously
- Anticipate the behaviour of other road users
- Maintain safe distances from other vehicles
- Handle difficult weather and road conditions
However, even with advanced training, Truck drivers still cannot see everything around them at all times. This is why other road users must also understand how blind spots work and adjust their driving accordingly.
Tips for Driving Safely Around Truck
To stay safe when sharing the road with large trucks, keep these key tips in mind:
- Stay out of truck blind spots whenever possible.
- Pass trucks quickly and safely without lingering beside them.
- Never drive too closely behind a truck.
- Always keep your headlights on in poor visibility conditions.
- Ensure the truck driver can see you in their mirrors.
- Give snow plows and other large service vehicles plenty of space.
Final Thoughts
Truck are essential for transporting goods and keeping supply chains running, but their size creates visibility challenges that smaller vehicles do not face.
By understanding blind spots and No Zones, drivers can make smarter decisions when sharing the road with large trucks. Simply staying visible, keeping your distance, and avoiding blind spots can significantly reduce the risk of accidents.
Safe driving around Truck isn’t complicated it just requires awareness and a little extra space.
