  4. In the unlikely event of an accident or breakdown, immediately evacuate to a safe place.

If you inform the following vehicle of the danger with a hazard lamp, triangular stop sign, flares, etc., pay close attention to passing vehicles and immediately evacuate to a safe place such as outside the guardrail. Also, please report by emergency phone.

  5. Be careful of rear-end collisions at the end of traffic jams
