Final answer:
In a traffic accident, move your vehicle to the side of the road if possible, and then wait for the police to arrive, ensuring your safety and not obstructing traffic.
Step-by-step explanation:
When involved in a traffic accident, it is advisable to ensure safety first. If possible, move your vehicle to the side of the road, away from traffic. This action helps prevent further accidents and allows traffic to continue flowing. Staying in your current lane could be dangerous and cause additional hazards. Exiting your vehicle immediately is not always safe, especially on busy roads. Instead, you should check for safety before exiting. Once you are in a safe location, you should then wait for the police to arrive, especially if there are injuries or significant vehicle damage.
