Road safety is a significant concern in Japan, with the government striving to reduce accident numbers. Special attention is given to tunnel safety, considering the country's infrastructure is dense with such structures. Accidents like these instigate public demand for enhanced safety protocols and infrastructure checks.

Like Japan, the US and EU also regard road safety highly, with stringent traffic rules enforced and regular road infrastructure checks performed. Any significant accident usually prompts a thorough investigation and potentially leads to efforts to avoid a recurrence, involving public awareness campaigns, rule revisions, or infrastructure improvements when applicable.
