When operating under restricted speed, what action should you take if you detect an obstruction ahead?

• A. Be prepared to stop short of the obstruction.
• B. Continue at the same speed and report later.
• C. Stop immediately.
• D. Speed up to pass the obstruction.

Answer: (A)

Restricted speed means you must be able to stop within the distance you can see and react to any obstruction ahead. When you spot an obstruction, the proper action is to be prepared to stop short of it, slowing or stopping as needed so you can avoid contact. Continuing at the same speed and reporting it later provides no guarantee you can stop in time; stopping immediately is only necessary if the obstruction is right in your stopping distance, and speeding up to pass is unsafe and against restricted-speed rules.
