What should you do if a vehicle in front of you suddenly stops?

Answer: B — Apply the two-second rule to ensure safety

When a vehicle in front of you suddenly stops, the most prudent action is to apply the two-second rule to ensure safety. This rule promotes maintaining a safe following distance, which provides enough time to react if the vehicle ahead stops unexpectedly. By giving yourself a buffer of at least two seconds, you reduce the risk of a collision, as the extra space allows for quicker and safer braking maneuvers. Maintaining this distance is essential, especially in unpredictable traffic situations, where conditions may change rapidly. It enables better awareness of what’s happening on the road ahead and allows time for necessary reactions, such as braking or swerving if needed. It's a fundamental principle for safe riding and is particularly crucial for motorcycle riders, who may not have the same protection as those in cars.
