modify requirements for a vehicle approaching a vehicle that is stopped or occupying the shoulder of the highway with warning lights flashing.

This bill modifies traffic laws in South Dakota to clarify requirements for vehicles approaching those stopped on the shoulder with flashing warning lights. It directly affects drivers on highways by specifying how they should behave when encountering emergency or disabled vehicles in that position. The key provision updates existing rules to ensure approaching drivers maintain a safe distance and reduce speed when warning lights are active. This change aims to improve safety for both the stopped vehicle occupants and passing traffic by establishing clearer expectations for highway driving behavior.
