Driving in **fog** presents several challenges, such as **poor visibility** of the road, signs, and other vehicles, as well as **reduced tire grip** due to moisture on the ground. To improve safety in these conditions, it is crucial to **increase the following distance** with other vehicles. This is because, with less grip, the vehicle needs more space to brake safely. Maintaining a greater safety distance allows for more time to react to any unforeseen events, reducing the risk of accidents. Additionally, it is important to drive slowly and pay attention to signs and road markings to navigate safely in the fog.
