Driving a motor vehicle suddenly encountered heavy fog.

When driving a motor vehicle in foggy days, you should slow down and turn on the low beam, and at the same time turn on the fog lamp and the danger warning flash to keep the distance between vehicles. If visibility is very low, you should try to pull over and wait.

Mass fog means that the temperature is lower than the dew point temperature, and the water vapor in the atmosphere condenses into small water droplets or ice crystals, forming dense fog, which brings great visual obstacles to drivers and increases the difficulty of road traffic management. When encountering foggy weather, drivers should strictly abide by the relevant provisions of the Road Traffic Safety Law of the People's Republic of China and take the following measures: (1) Slow down: when the road is slippery and the line of sight is blurred in foggy weather, drivers should slow down appropriately and follow the principle of looking before moving; (2) Turn on the low beam: On the premise of ensuring that his sight is not limited by blind spots, the driver should turn on the low beam as much as possible to enhance his vision at night and in foggy days. (3) Turn on fog lights and hazard warning flashlights: According to the size and speed of the goods carried by the vehicle, the driver should turn on the front and rear fog lights and hazard warning flashlights in time to ensure that the front and rear vehicles can see the vehicle clearly. (4) Keep the distance between cars: When there is fog, the visibility of the road is limited and the driving speed slows down, but enough distance between cars must be kept, so that there is enough safe distance to prevent traffic accidents such as rear-end collision. (5) If the visibility is extremely low, you should try to wait by the side to ensure your own safety.

What kind of civil or criminal responsibilities should drivers bear when they encounter traffic accidents caused by careless driving in foggy days? If a driver causes a traffic accident due to negligence, he may be investigated for civil or criminal responsibility according to law. Civil liability includes compensation for direct losses caused by other vehicles, pedestrians and other property; Criminal responsibility refers to the situation that violation of traffic laws causes casualties or heavy property losses, and criminal responsibility can be investigated according to law. Penalties ranging from light to heavy include: administrative detention, revocation of motor vehicle driver's license and fixed-term imprisonment.

When encountering foggy weather, drivers should seriously abide by relevant laws and regulations and take corresponding measures to ensure driving safety. At the same time, keep the distance between cars and drive carefully to ensure the safety of yourself and others.
