SIPDE: The PA Motorcycle Rider Course promotes the following method of actions:
Scan the road ahead
Identify possible unknown hazzards ahead. Visibility may be limited to a 4 second immediate path of travel.
Predict that unknown hazards will enter your path.
Decide to increase space and time to react. SLOW down.
Execute by rolling off the throttle and using your brakes to reduce speed and increase visibility as much as possible. Provide positive traction (roll on throttle gently).
