Which is the maximum allowable speed when passing a stationary emergency vehicle with lights activated on a two-lane roadway?

When passing a stationary emergency vehicle with its lights activated on a two-lane roadway, the law establishes a maximum allowable speed of 20 MPH below the posted speed limit. This regulation is designed to ensure the safety of emergency personnel who may be working on the roadside, as well as to allow for unforeseen circumstances that may arise when vehicles are passing by a scene of emergency.

Adhering to the 20 MPH reduction helps to minimize potential hazards, reduce the risk of accidents, and maintain a safe environment for both responders and passing motorists. By providing this buffer, the law recognizes the need for caution and control in situations where emergency services are present.
