The reason why motor vehicles are prone to skidding inside tunnels is that the tunnel floor is relatively slippery. Precautions for driving in tunnels: It is necessary to appropriately reduce speed before entering the tunnel. Tunnel entrances usually have clear speed limit signs to remind drivers to slow down before entering. The lanes inside the tunnel are typically narrower than those outside, so reducing speed helps drivers accurately assess road conditions. At the same time, it is essential to turn on the low beam headlights. Due to the relatively dim lighting inside the tunnel, drivers may experience temporary "blindness," making it necessary to use low beam headlights to clearly see the road ahead. It is important to note that using high beam headlights inside the tunnel is strictly prohibited, as it is an extremely dangerous action. Requirements for driving in highway tunnels: Changing lanes or overtaking is prohibited inside tunnels. Due to the limited space and poor lighting conditions, lane changes and overtaking can easily disrupt the normal flow of other vehicles. Additionally, most tunnels are now equipped with comprehensive camera surveillance systems, and illegal lane changes will result in a 3-point penalty and a fine.

When does a new car need its first maintenance?

The first maintenance for a new car should be done within 3 to 5 months, typically when the mileage reaches 3000 to 5000 kilometers. When the time is approaching, the 4S dealership will kindly remind the owner when it's time for maintenance. For the first maintenance of a new car, it is generally based on whichever comes first. If the time is up but the mileage hasn't been reached, the first maintenance should still be performed; otherwise, it will be considered as missing the maintenance, and the car's information cannot be recorded in the national warranty system. The first maintenance items for a car include: changing the engine oil and oil filter, cleaning the air filter, checking the generator belt and wiper blades for damage; inspecting the levels of various fluids to ensure they are normal; checking the tire pressure for normal levels and looking for signs of uneven wear, bulges, or damage; examining the car's chassis, including the brake pads, brake discs, connecting rods, ball joints, and CV joints for any scratches; and verifying that all switches and lights are functioning properly. Important notes for the first maintenance include: making an appointment in advance; bringing essential items such as the maintenance manual and vehicle registration certificate; and recording any faults or questions encountered during daily driving to inform the staff during the first maintenance registration.
