How should a rider cross railroad tracks or other surface hazards that run parallel or at an angle to the path of travel?

When crossing railroad tracks, seams, or grooves, the rider should aim to cross at an angle as close to perpendicular (90 degrees) as practical so the tires meet the hazard squarely and are less likely to get caught or deflected in a groove. It is generally not necessary to make an extreme turn to cross exactly at 90 degrees — a moderate angle while maintaining a steady, controlled speed is fine and safer than a sudden swerve. Keep a firm grip, stay relaxed, and avoid hard braking on the slippery surface. The goal is to prevent the front tire from sliding along or dropping into a groove.
