When encounter a TSR, which action sequence is correct?

• A. Slow to the TSR speed, adhere to limit, and report discrepancies to the dispatcher.
• B. Maintain current speed and ignore the TSR
• C. Increase speed to clear it quickly
• D. Only slow when you see it on the dashboard

Answer: (A)

Temporary speed restrictions require immediate compliance to a reduced speed shown for that work zone. When you encounter one, you must slow to the TSR speed, follow the posted limit through the restricted area, and promptly report any discrepancies between the trackside TSR and what you’re seeing to the dispatcher. This keeps you within the safe, authorized speed while crews are protected and enables the dispatcher to adjust instructions if something is off.

Other approaches ignore the restriction, try to speed through to “get it over with,” or rely on the onboard dashboard alone. Those options violate the rule to follow the trackside TSR and can create dangerous situations for crews and equipment.
