The vehicle on-board unit has a vehicle traveling condition detecting section, an automatic brake light triggering section and a brake light activating section. The vehicle traveling condition detecting section detects the vehicle traveling condition indicative of a potentially inadequate safety zone. The automatic brake light triggering section outputs a brake light activation signal upon determining a predetermined condition has been satisfied based upon the detected vehicle traveling condition. The brake light activating section activates the brake lights without a braking operation being performed upon receiving the brake light activation signal from the automatic brake light triggering section.
