What must all vehicles be equipped with due to weather conditions?

Vehicles must be equipped with heating or ventilation systems to ensure the safety and comfort of occupants under various weather conditions. These systems are essential for maintaining a suitable temperature within the vehicle, especially in extreme temperatures—whether very cold or very hot. In cold weather conditions, a heating system prevents hypothermia and ensures that drivers maintain full control and awareness without the distraction of discomfort. In hot weather, ventilation helps to regulate interior temperatures and reduces the risk of heat-related illnesses.

This requirement is particularly important for jailers who may transport individuals, as it is their responsibility to ensure the humane treatment of detainees, which includes protecting them from extreme weather conditions. Proper climate control within a vehicle is therefore crucial for safeguarding the health and safety of both the jailers and the individuals in their custody. Other options, while they may pertain to vehicle functionality, do not directly address the critical need for climate control in relation to weather conditions.
