A pilot waits at a runway holding position. Red runway entrance lights come on. What must the pilot do?

  1. Cross the runway quickly, because ATC cleared the pilot
  2. Taxi onto the runway and wait for the lights to go out
  3. Stay stopped and tell ATC about the red lights
  4. Turn off the transponder and cross
Show answer

Correct answer: Stay stopped and tell ATC about the red lights

Red lights mean it is unsafe to enter or cross. The pilot must not cross and must contact ATC.
