What must drivers do when driving at night regarding their speed?

When driving at night, the primary concern for safety is ensuring that drivers can stop safely within the distance illuminated by their vehicle's headlights. This makes driving at speeds that allow for safe stopping the most appropriate choice.

At night, visibility is significantly reduced, and various factors such as wet or icy roads, wildlife crossing, or other vehicles can create hazards that require a driver to react quickly. Keeping the speed within a range that allows for a safe stop is essential, as it helps drivers maintain control of their vehicle and reduces the likelihood of accidents.

Driving as fast as the speed limit allows does not take into consideration the reduced visibility and potential hazards of nighttime driving, which could lead to dangerous situations. Similarly, driving with high-beam lights on at all times is not advisable as it can blind oncoming drivers and create further risks. Adjusting speed according to road type is important, but the most critical factor at night is the ability to stop safely within the visibility range provided by the headlights. Therefore, prioritizing safe stopping distances is crucial when driving after dark.
