Which vehicle is required to have a red light on the rear when driving at night?

Emergency vehicles are required to have a red light on the rear when driving at night to enhance visibility and ensure that other road users can easily recognize their presence. The use of red lights on emergency vehicles serves a critical purpose in alerting other drivers to yield and allow these vehicles to pass, especially during urgent situations such as responding to emergencies or transporting critical patients.

Passenger cars, motorcycles, and trucks typically do not have the same requirement for red rear lights. Instead, they are usually equipped with standard taillights, which are generally red but do not serve the specific function of signaling urgency as emergency vehicles do. Therefore, the presence of a red light on the rear of emergency vehicles is a crucial element of traffic safety, helping to facilitate a timely response to emergencies.
