What action should you take if your throttle sticks?

Answer: B — Pull in the clutch and apply the brakes gently to stop safely

If your throttle sticks while riding, pulling in the clutch and applying the brakes gently is the safest action to take. This method allows you to disengage the engine power from the wheels, reducing the risk of a loss of control while also allowing you to decelerate safely. By using the clutch, you can maintain ability to steer while managing your speed. Gently applying the brakes helps you slow down without abrupt movements that could destabilize the motorcycle. It's crucial to maintain control during such situations to prevent accidents. The other options do not effectively address the issue. Yelling for help would not assist in managing the immediate danger, accelerating could exacerbate the situation, and ignoring the throttle issue could lead to loss of control, making a potentially dangerous situation even worse.
