What is the safest technique for a two-wheeled motorcycle rider when crossing railway tracks or tram rails embedded in the road surface at an angle?

1. Cross parallel along the length of the rail
2. Steer the motorcycle to cross the tracks as close to a 90-degree right angle as possible (尽量垂直于铁轨方向通过)
3. Accelerate to maximum speed and jump over the rails
4. Apply the front brake firmly while crossing over the rail head
