Which safety measure is critical when riding at night?

Carrying a flashlight is essential when riding at night because it allows the rider to see and be seen in low visibility conditions. A flashlight can illuminate the path ahead, helping to identify potential hazards such as uneven terrain, obstacles, or even animals that may not be visible in the dark. Additionally, having a light source helps other people, whether they are fellow riders or vehicles, to see the rider, which enhances overall safety.

In contrast, using a loud horn may not be effective in general horse riding situations and could startle both the horse and nearby animals. Wearing appropriate footwear is important for overall riding safety but does not specifically address the challenges of nighttime visibility. Riding without other people can pose risks, as it may lead to feeling isolated or lacking immediate assistance in case of an emergency. Thus, the use of a flashlight stands out as the most critical safety measure for navigating the challenges of nighttime riding.
