What should you do when traffic is slow and heavy, and you must cross railroad tracks before reaching the upcoming intersection?

  1. Begin crossing when the vehicle in front of you is crossing the tracks.
  2. Wait on the tracks until the stoplight at the intersection turns green.
  3. Wait until you can completely cross the tracks before proceeding. ✓

Answer: C. Wait until you can completely cross the tracks before proceeding.

When traffic is slow and heavy, wait until you can completely cross the tracks before you start across.

Why this is the answer

The handbook says never to stop on the railroad tracks, and it tells you to hold back and not begin crossing if there is not enough room to get all the way across. In backed-up traffic the car ahead may stop short of the far side, leaving you sitting on the rails. Waiting until there is room to clear the tracks keeps you off them, which matters because being on the tracks puts you at risk of injury or death.

Why the other answers are wrong

Remember it

Before you roll onto the rails, look at the space on the far side and ask yourself: will my whole car fit there?
