Final answer:
To ensure your safety while crossing railroad tracks, avoid talking on the phone, listening to music, and running.
Step-by-step explanation:
When crossing railroad tracks, it is important to avoid all of the above: talking on the phone, listening to music, and running.
Talking on the phone or listening to music can distract you and prevent you from hearing approaching trains or warning signals. Running can increase the risk of tripping or falling on the tracks, which can be very dangerous.
It is crucial to focus on your surroundings, stay alert, and obey all signs and warnings when crossing railroad tracks to ensure your safety.
