You are approaching a railroad crossing that has no visible gates or flashing lights, but has a standard crossbuck. You should:
Approach all tracks with extreme caution and cross only when you know that there is no train coming.
Turn your radio down to hear if there may be an approaching train.
Only continue once cleared to do so by a flagger, if applicable.
All of the above.
