A driver’s developed psychological and cognitive ability to drive a vehicle and make safe decisions in conditions of limited visibility, such as thick fog, heavy rain, darkness, dust, or other factors that reduce the ability to observe the road, vehicles, and pedestrians. This ability involves a combination of sustained attention, quick reactions, precise cognitive processing to estimate distance and speed, and the ability to control emotions in stressful situations, enabling adaptation to potential hazards and effective preventive behavior. It also relies on the use of visual controls and preventive technologies, as well as on the continuous assessment of environmental conditions to ensure road safety. This is an important indicator of the driver’s ability to cope with critical and difficult traffic situations.
