Sharing the road with tractor-trailers requires extra caution from drivers. These massive vehicles play a vital role in transporting goods across the US, but their size also introduces unique hazards for other drivers.
One of the biggest risks is from their blind spots, often called “no-zones.” These areas are not just minor gaps in visibility—they’re large zones where your vehicle can completely disappear from the truck driver’s view.
It’s important to know where these blind spots are and how to stay out of them, avoid truck accidents, and make the road safer for everyone.
Why Tractor-Trailer Blind Spots Are So Dangerous
Unlike passenger vehicles, tractor-trailers sit high off the ground and stretch up to 75 feet in length.
Side mirrors provide some visibility, but even the best setups leave large blind spots. When a car enters one of these no-zones, the truck driver may not know it’s there. This can lead to dangerous lane changes, turns, or stops that catch the other driver off guard.
Accidents involving blind spots tend to be severe because of the size and weight difference between the vehicles. A tractor-trailer typically weighs 20 to 30 times more than a car. When collisions happen in these blind zones, they often involve crushing impacts, rollovers, or multi-vehicle pileups.
Where the Blind Spots Are
Tractor-trailer blind spots exist on all four sides of the vehicle, but some are larger than others.
On the driver’s side, the blind spot extends from the cab halfway down the trailer. On the passenger side, it stretches further, often the entire length of the trailer and several lanes wide. The rear blind spot runs about 30 feet behind the trailer, while the front blind spot covers roughly 20 feet directly in front of the cab.
If you can’t see the truck driver’s face in their side mirror, they can’t see you either.
That simple rule offers a helpful way to judge your visibility. Even though trucks have mirrors and cameras, those tools can’t fully eliminate these blind areas, so drivers in smaller vehicles need to adjust accordingly.
Staying Out of the No-Zones
- The safest move when approaching a tractor-trailer is to avoid lingering beside or behind it.
- Passing on the left is always preferable because the blind spot on the driver’s side is smaller. When passing, do so quickly and return to your lane only after you can see the entire truck in your rearview mirror.
- Don’t cut directly in front of the truck—its stopping distance is far greater than that of a car, and sudden braking could lead to a rear-end collision.
- On multilane roads, keep extra space between your vehicle and any trucks nearby.
- Don’t hover in the right lane next to a trailer, especially near on-ramps or exits where trucks may be merging.
- If you find yourself stuck in a truck’s blind spot, either drop back to increase your following distance or speed up to safely pass and clear the area.
What to Do in Heavy Traffic
Congested roads limit maneuvering room, but the same rules apply. Try to anticipate truck movements and avoid being boxed in. Be mindful of turn signals, especially on the right side. Tractor trailers need extra space to make wide turns, and if you’re in the blind spot when that happens, you could get trapped or sideswiped.
When merging near a truck, give ample warning and avoid abrupt lane changes. Signal early and wait for a large enough gap to ensure you’ll clear the truck’s front blind spot. In stop-and-go traffic, resist the urge to squeeze into tight spaces around a big rig.
It’s safer to maintain a visible and predictable position than to dart in and out of lanes.
Maintaining Visibility at Night and in Poor Weather
Low visibility conditions only worsen the risks around a tractor-trailer.
Rain, fog, snow, and darkness reduce sightlines and mirror effectiveness. During these times, keep headlights on low beam, use windshield wipers consistently, and avoid sudden movements. Trucks need more time to react in these conditions, and you should give them even more space than usual.
Reflective tape and lights help mark the contours of large trucks, but they won’t tell you where the blind spots are. Drivers should remain cautious and patient, especially during bad weather or nighttime driving. If possible, wait until conditions improve before attempting to pass or merge near a large truck.
