When approaching railroad tracks with flashing red lights, you must:

  1. Stop your vehicle

  2. Slow down and proceed with caution

  3. Drive around the railroad tracks

  4. Sound your horn

The correct answer is: Stop your vehicle

When approaching railroad tracks with flashing red lights, the only correct action is to stop your vehicle. This is because flashing red lights indicate a train is approaching and you must come to a complete stop to avoid a potential collision. B is incorrect because you should not proceed at all, regardless of speed. C is incorrect because it is illegal and dangerous to drive around railroad tracks. D is incorrect because sounding your horn does not guarantee your safety and it is not a legal requirement.
