Driving in **heavy rain** presents several challenges that can affect road safety. One of the main issues is that **tires have less grip** on wet pavement. This means that the vehicle needs more space to stop, as the **braking distance increases**.

To handle these conditions safely, it is advisable to **increase the safety distance** with the vehicle in front. This provides more time and space to react in case sudden braking is necessary. Additionally, it is advisable to **reduce speed** to have better control of the vehicle and minimize the risk of accidents.

In summary, when driving in heavy rain, it is crucial to increase the safety distance and reduce speed due to the reduced tire grip and increased braking distance.
