1. Both ways
When approaching a railroad crossing, you must look both ways.
Context:
When you need to cross train tracks, go to the designated destination, look at both routes, and cross the tracks quickly without stopping. Remember that it is unsafe to stand within 15 meters of a railway line.
Be aware that your glasses or A-pillars may be blocking your view so adjust your body so that you can see yourself around. Listen to any train signals even if you can't see them. If you do not see or hear anything, look again and continue. Use the highest gear without switching to disconnect.
