What is the correct action when driving on a road that becomes slippery due to rain?

When driving on a road that becomes slippery due to rain, the appropriate action is to reduce your speed gradually. This is essential because wet surfaces can lead to a loss of traction, making it more challenging to control your vehicle. By decreasing your speed, you allow for better contact between your tires and the road, which helps maintain traction and reduces the likelihood of skidding or losing control.

Maintaining a lower speed also gives you more time to react to unexpected obstacles or changes in road conditions. It allows for smoother braking and steering, which are crucial for staying safe in wet conditions. As surfaces become slick, a gradual reduction of speed is vital to adjust your driving behavior appropriately for the changing environment.

Increasing speed, on the other hand, can worsen traction issues and lead to a higher risk of accidents, while making sharp turns can result in losing control. Changing tires could be a valid consideration in the long term for overall safety, but it's not an immediate action warranted by slippery road conditions.
