When approaching an intersection where a vehicle may cross your path, you should do what to reduce your reaction time?

To reduce your reaction time when approaching an intersection where a vehicle may cross your path, covering the clutch and brake is the most effective action. By covering the clutch and brake, a motorcyclist prepares to respond quickly to any potential hazards, allowing for immediate control over the motorcycle. This action keeps the rider ready to slow down or stop without the delay of locating and actuating the controls.

Accelerating may not be a defensive maneuver; it could lead to less reaction time if an obstacle suddenly appears. Turning on your headlights is useful for visibility but doesn't directly contribute to reducing reaction time. Sounding the horn might alert other drivers, but it does not enhance your ability to respond quickly to an unexpected situation. Thus, covering the clutch and brake is the optimal choice for maximizing readiness and safety in navigating intersections.
