What should you do if you witness a traffic accident?

If you witness a traffic accident, the best course of action is to call 911, report the details, and provide assistance if it is safe to do so. This response ensures that emergency services are notified promptly, allowing for quick medical attention and necessary interventions. Reporting details accurately helps law enforcement document the incident correctly, which is crucial for any investigations that follow. Assisting those involved, if it's safe, reflects a responsible and compassionate approach, as many accidents may leave individuals in need of immediate help until professional responders arrive.

Additionally, while taking photographs may seem helpful, it is not a priority compared to ensuring that emergency services are called and that you are providing assistance as needed. Driving away to avoid being involved would be irresponsible, as it could leave those in need without help. Attracting attention by yelling could create further chaos and may not effectively bring assistance. Thus, calling emergency services and aiding those involved is the most appropriate and constructive action in such a scenario.
