The blind spot locations of a large truck: 1. Front blind spot: The front of a large truck is a semi-blind area, especially the area immediately adjacent to the body, which has significant visual blind spots. The danger zone varies depending on the size of the truck. 2. Left-side blind spot: The left-side blind spot is near the rear of the cargo box and is relatively smaller than the right-side blind spot. However, when positioned at the left rear wheel, only half of the body can be seen through the rearview mirror. 3. Right-side blind spot: The right-side blind spot of a large truck is the most dangerous among all its blind spots. It extends from the end of the cargo box to the end of the driver's cabin, covering an area approximately 1.5 meters wide from the truck. The larger the cargo box, the larger the blind spot. 4. Rear blind spot: The area directly behind a large truck is a complete blind spot, making it almost impossible to see vehicles following closely behind.

Veteran truck drivers are well aware of how dangerous blind spots can be. The area directly in front of the truck, about two meters, is a dead zone—the driver's seat is so high that small cars or pedestrians in front of the cab are completely invisible. The blind spot on the right side of the truck is the most terrifying, extending from the passenger seat all the way to the rear for about three meters. Cyclists or pedestrians in this zone go completely unnoticed by the driver. The rear of the truck is another high-risk blind spot, especially when reversing—drivers often purely on instinct. What scares me the most is the inner wheel difference during turns: while the front wheels clear an area, the rear wheels swing into a two- to three-meter zone beside the truck, posing a deadly threat to anyone standing there. Over years of hauling freight, I’ve witnessed countless accidents caused by blind spots. Driving a big rig means always assuming people are nearby and constantly checking those mirrors.

When conducting safety training for logistics companies, I always emphasized the blind spots of large trucks. The area directly in front of the truck's cab is an absolute blind zone—a child crouching there would be completely invisible. The right-side rearview mirror only covers a partial area, leaving a large section from the middle door backward completely out of sight, especially dangerous at night with poor visibility. The left-side blind spot is relatively smaller, but there are still dead angles in the rearview mirror during turns. The area five to six meters behind the truck is also a high-risk zone. It's crucial to remind other vehicles not to approach these areas, as large trucks have wide turning radii, and the blind spots caused by the inner wheel difference often pull people under the vehicle. It's recommended to install convex mirrors and backup radars on trucks to effectively reduce accidents.

During the truck driving test, the instructor repeatedly reminded us about blind spots: the area directly in front of the vehicle within three meters is invisible due to the high lower edge of the windshield. The right-side blind spot is the widest, spanning about two to three lanes. The rear of the truck is like a black hole, relying entirely on radar for reversing. When turning, the inner wheel follows a tighter path, creating an inner wheel difference blind spot. Pedestrians and vehicles must actively avoid these areas, maintaining a safe distance of at least five meters. It's recommended to install blind spot cameras on large vehicles, but the most practical approach remains driving slowly and staying observant.

Last time at a highway service station, I chatted with a truck driver. He pointed to his red heavy-duty truck and said, 'The area under the front of the cab is a death zone—you simply can't see low obstacles. The right side of the truck is like a black hole; it's especially dangerous when e-bikes try to overtake from that side. The rearview mirrors only show the back half of the truck, and there's a blind spot within three meters behind the vehicle. Every time you make a turn, you have to be extra cautious about the inner wheel difference zone, as the wheel track can shift inward by over a meter.' He advised car drivers to avoid driving parallel to large trucks, to stagger lanes whenever possible, and to accelerate past intersections to avoid lingering in blind spots.

When riding a motorcycle, I was taught by my instructor about the blind spots of large trucks. There are five danger zones around the truck body: The area right in front of the truck is like a cliff edge, completely invisible. The right side, from the door to the rear wheel, is the most lethal, with huge blind spots in the mirrors. The rear of the truck is like a wall blocking the view. During left or right turns, the inner wheels follow an arc, making the inner zone wider than expected. These are areas where the driver truly can't see you, so maintaining a safe distance is crucial. Now, whenever I see a large truck, I proactively slow down and keep my distance—better to stop for three minutes than rush for one second. A three-meter radius around the truck is a danger zone.
