Traffic beyond a railroad crossing is stopped, with too little room for your whole car to clear the tracks. What should you do?
Blue A approaches a single-track railroad crossing with a US RAILROAD CROSSING crossbuck. Silver B is stopped just beyond the far rail, with less than one car length of clear road behind it. Both vehicles have nearby letter labels.
Correct answer: Wait until there is room for your whole car
Why
Before entering, make sure there is enough space for your entire vehicle on the far side. Never queue on railroad tracks. Signals permitting travel do not create space beyond the crossing.
