Blind spot (automobile)

A blind spot in a vehicle is an area around the vehicle that cannot be directly observed by the driver while at the controls, under existing circumstances. Blind spots exist in a wide range of vehicles: cars, trucks, motorboats and aircraft.

  • checked by turning one's head briefly (risking rear-end collisions),
  • eliminated by reducing overlap between side and rear-view mirrors, or
  • reduced by installing mirrors with larger fields-of-view

Other areas that are sometimes called blind spots are those that are too low to see behind, in front, or to the sides of a vehicle, especially those with a high seatinpot.

Motorboats

Blind spots also exist in front of boats. When the boat accelerates, the bow rises, increasing the size of the blind spot. Large vessels can have up to several hundreds of meters of blind spot. To address this, cameras are sometimes placed in the front of the vessel to cover the missing field of view.
