Would you enter a railroad crossing if the flashing lights are activated?

Not unless you want to be Killed or Injured for life. A lot of people have tried to beat the train to the crossing and it was the last thing they Ever did. Train Versus Human = Train 1 - Human Nothing but blood and guts.

* Added - In all US states, the flashing lights activated means stop prior to entering the crossing. If there are no crossing gates, most US states allow you to proceed after stopping and checking to be sure no train is approaching. If there are crossing gates as well, it is not legal to drive aroound the gates or through the crossing while the gates are going up or down in any state in the US.
