Answer 1

At railroad crossings that are marked only with a stop sign, you must stop and then proceed only when you determine that no train is approaching.

Step-by-step explanation:

In railroad crossings that are marked only with a stop sign, you must stop and then proceed only when you determine that no train is approaching.

This is because a train has the right of way at a railroad crossing and it can be extremely dangerous to cross when a train is approaching.
