Which feature is crucial for night driving in a tractor-trailer?

Properly functioning headlights are essential for night driving in a tractor-trailer because they significantly enhance visibility in low-light conditions. Trucks often operate under challenging circumstances, and adequate lighting allows drivers to see the road, other vehicles, and potential obstacles ahead. Bright and correctly aimed headlights ensure that the driver can react timely to any dangers, increasing safety for both the truck operator and others on the road.

While features like high visibility paint can help with overall visibility during daylight or in adverse weather conditions, they do not provide the illumination necessary for night driving. Drift control systems and rearview cameras, although beneficial in certain scenarios, do not directly address the need for clear visibility when driving at night. Thus, the most crucial feature for navigating safely in the dark is having headlights that function properly.
