Every vehicle has blind spots on both sides, particularly the area that is on the right side of a vehicle and just behind the passenger window. If another vehicle is in that area, it is almost impossible to see him or her in your mirrors. There is also a blind spot right next to the driver’s side window and next to the rear passenger window.
Larger vehicles, like commercial trucks, have a blind spot directly in front of them. On commercial trucks this area extends to about 20 feet in front of the truck.
Commercial trucks also have a 30-foot blind spot behind the trailer. The blind spot on the right side extends out two lanes, while the blind spot on the driver’s side extends from behind the cab to a little over halfway to the back of the trailer.
