Question 4039

Before a railroad crossing, two alternately flashing red lights indicate…

  1. that the crossing is about to close and vehicles must cross quickly.
  2. that passage is temporarily prohibited.
  3. that drivers may proceed with extreme caution.
Show answer and explanation

Correct answer: that passage is temporarily prohibited.

Two red lights flashing alternately before a railroad crossing mean you must not proceed, even if you cannot see the train. You must wait before the crossing until they go out. They do not give you time to cross quickly or allow you to proceed with caution, which is what a flashing yellow light calls for.
