If you are approaching a railroad crossing that does not have gates or lights and you see an oncoming train, what should you do?
Answer: C — Slow down and stop
It's important to slow down and stop at a railroad crossing that does not have gates or lights when an oncoming train is approaching. This is the safest option, as speeding up or driving quickly across the tracks presents a danger of colliding with the train. Turning around and finding another route may also not be safe, as it could involve risky maneuvers or driving on unfamiliar roads. Therefore, it is best to follow posted signs and signals and to always be cautious when approaching railroad crossings to ensure the safety of yourself and others.
