You should always look both ways at

Explanation

Always look both ways at railroad crossings, crosswalks, and intersections. Pedestrians, vehicles, or trains may approach from either direction. Follow the left-right-left rule: Look to your left first because pedestrians or vehicles coming from the left are closer to you. Then look to your right. Finally, take one more look to your left before you proceed. You might see a pedestrian or vehicle on your left that you didn't see the first time you looked.
