Final answer:
Counter steering should be performed after your front wheel leaves the roadway. This technique is crucial for regaining control and preventing accidents, and involves the principles of angular momentum and gyroscopic forces.The correct answer is option 2.
Step-by-step explanation:
When your front wheel leaves the roadway at high speed due to an obstruction ahead on the shoulder, you should counter steer after your front wheel leaves the roadway. It's important to regain control of the vehicle before applying the counter steering technique. When counter steering, the goal is to adjust the direction of the vehicle to get back onto the road safely and prevent an accident.
In the context of riding a motorcycle, this maneuver is part of managing a vehicle's dynamics. Counter steering on a motorcycle at high speeds causes it to lean in the opposite direction of the turn, which is key for navigating bends or making quick adjustments. The physics of counter steering involve the principles of angular momentum and gyroscopic forces. This also explains why a motorcycle turns left when pulling back lightly on the right handlebar - a rightward push causes a leftward lean due to the gyroscopic effect.
