You reach a railroad crossing where the lights are flashing but you don't see a gate arm. What should you do?

Pick an answer

1. Cross anyway since a missing gate means the crossing is inactive
2. Proceed slowly since lights without a gate are just a caution, not a stop requirement, the same as a yellow traffic signal would be treated
3. Only stop if you can also hear a train whistle
4. Treat the flashing lights the same as a full stop requirement and do not cross until it's clear
