What is the safest way to judge whether it's clear to proceed at a railroad crossing?

Pick an answer

1. Rely only on a passenger in the front seat to check
2. Assume it's clear if no train was visible the last time you crossed, since most schedules keep at least twenty minutes between trains
3. Judge only by whether other vehicles are crossing
4. Look and listen in both directions from a stop close enough to see clearly, but far enough to react
