If the temporary reduce speed sign is not released by the dispatcher, the 10 MPH limit remains until the leading end of the train passes the sign by how many miles?

• A. 1 mile
• B. 2 miles
• C. 3 miles
• D. 4 miles

Answer: (B)

Temporary speed restrictions stay in effect until the dispatcher releases them; if there’s no release, you don’t snap back to normal speed just because the front of the train has passed the sign. The rule gives a fixed clearance distance to ensure the train is well past the work zone and there’s a safety margin for any delays or follow-on trains. The standard distance used is two miles, so the 10 mph limit remains until the leading end has passed the sign and traveled two miles beyond it. This guarantees the area around the sign is fully cleared before resuming normal speed.
