What are the precautions for vehicles passing through tunnels?

[HoldenRose]

Here are the precautions for vehicles passing through tunnels: 1. Before entering the tunnel, carefully observe the height and width limit signs and text instructions at the entrance. Vehicles that do not meet the requirements are not allowed to enter the tunnel; 2. Before entering a one-way tunnel, carefully observe whether there are oncoming vehicles. When allowed to pass, sound the horn appropriately or turn on the width indicator lights; 3. When entering a two-way tunnel, drive on the right side, turn on the lights as needed, pay attention to oncoming vehicles, and avoid honking inside the tunnel; 4. Overtaking, reversing, making U-turns, and parking are prohibited inside the tunnel. In case of a vehicle breakdown, turn on the width indicator lights and tail lights, and try to move the vehicle outside the tunnel.
