What is the minimum legal distance you must keep behind an emergency vehicle running its siren and lights?
-
A.
The passing rule's 100-foot distance applies here.
-
B.
At least 300 feet is required by law. Correct
-
C.
A full block gap of about 500 feet is required.
The answer is "At least 300 feet is required by law."
California makes it illegal to follow within 300 feet of an emergency vehicle using its siren or flashing lights, so 300 feet is the minimum legal gap. Choice A tempts drivers who carry the 100-foot no-passing figure over from the passing chapter and apply it whenever a question asks for a distance measured against another vehicle.
The traps in the wrong answers
A. The passing rule's 100-foot distance applies here.
The 100-foot figure belongs to no-passing zones near intersections, not the follow-behind rule for active emergency vehicles. Carries the 100-foot no-passing distance over from the passing-rules section because both rules attach a distance to another vehicle.
C. A full block gap of about 500 feet is required.
The manual prohibits following within 300 feet; it does not require a full-block or 500-foot gap. Rounds the specific 300-foot rule up to the familiar city-block estimate rather than trusting the printed figure.
