Truck drivers cannot see other drivers within 30 feet of their rears, and their blind zones in front of the cab extend 20 feet in front of them. The blind area for big vehicles crosses one lane to the left.
Large vehicles, unlike cars, have significant blind zones directly behind them. Additionally, compared to vehicles, they have substantially greater blind areas on both sides. Long hooded tractors may have a 20-foot blind area in front of the vehicle. These "no zones" should be avoided.
The blind spots on a vehicle are known as no zones.
