Driving in the rain presents additional challenges because **tires have less grip on the road**, known as reduced adhesion. This means the vehicle needs more space to brake safely. Therefore, it is crucial to **increase the safety distance** with the vehicle in front.

- **Reduced adhesion:** When it rains, the mixture of water with dust and grease on the road can form a slippery mud, increasing the risk of the vehicle skidding.
- **Additional space needed:** In rainy conditions, it is recommended to leave at least one more second of space between your vehicle and the one in front to compensate for the reduced adhesion and ensure you can stop in time in case of sudden braking.
- **Additional precautions:** Besides increasing the distance, it is important to keep the tires in good condition, brake gently, and reduce speed to improve safety when driving in the rain.

In summary, increasing the safety distance in rainy conditions is essential to compensate for reduced adhesion and ensure safe driving.
