What effective action can the driver take to check the blind spot area not covered by the mirrors?

Question

DentroTest · Accepted Answer

The blind spot is the area around the vehicle that is covered neither by the driver's direct vision nor by the field of view provided by the rearview mirrors. On heavy vehicles such as trucks, these non-visible areas are especially large and critical. The correct technique, recommended by the DGT, for monitoring this space before maneuvers such as lane changes or turns is to take a direct look by turning the head slightly, which complements peripheral vision and the mirror's view without losing control of the path ahead. Staying in the center of the lane does not eliminate the lack of lateral visibility, and angling the mirrors outward while driving is not the recommended technique: readjusting them on the move distracts the driver and does not replace the checking glance.
