Tractor trailers have four primary blind spots, commonly referred to as "no zones." Here’s an overview of their locations:
-
Front No Zone: This area extends approximately 20-30 feet in front of the tractor trailer. It is difficult for drivers of the truck to see any vehicles directly in front of them.
-
Rear No Zone: This zone is located directly behind the truck, extending about 30 feet or more. Drivers following too closely may not be seen by the truck driver.
-
Side No Zones: There are two side no zones—one on the passenger side and one on the driver's side. These areas can extend a full lane width (approximately 2-3 feet) or more. The driver's side no zone is particularly large due to the height of the trailer, which obstructs the view of smaller vehicles.
-
Right Side No Zone: The right side no zone is often considered the most dangerous, as it can extend several feet beyond the right side of the trailer. Drivers on this side may be in danger of being in the truck's blind spot when the truck is turning right, potentially leading to collisions if the truck turns without seeing the smaller vehicle.
Most Dangerous No Zone: The right side no zone is typically considered the most dangerous. This is because many truck drivers are not able to see vehicles in this zone, especially when making right turns. If a smaller vehicle is in that area, it can lead to serious accidents due to the lack of visibility for the truck driver. Being in this zone increases the risk of a collision as drivers may underestimate the truck's turning radius and proximity.
