You are in a very heavy downpour. Your overall stopping distance is likely to be:

In a very heavy downpour, the overall stopping distance is likely to be doubled. This is primarily due to reduced traction between the tires and the wet road surface. Water on the road can create a layer that causes the tires to lose grip, which results in your vehicle taking longer to stop.

When it rains heavily, the visibility is also significantly reduced, which may affect your reaction time. In addition, the braking forces are not as effective on wet surfaces as they are on dry roads. All of this contributes to an increased stopping distance. Therefore, when driving in such conditions, it is crucial to maintain greater distance from the vehicle ahead and to reduce speed to compensate for the longer stopping distance. This understanding helps drivers adjust their behavior to ensure safety while driving in adverse weather conditions.
