The following are the precautions for vehicles passing through tunnels: 1. Meet the requirements: Before entering the tunnel, carefully observe the height and width traffic signs and written instructions at the entrance. Vehicles that do not meet the requirements are not allowed to enter the tunnel; 2. Observe oncoming traffic: Before entering a one-way tunnel, carefully observe whether there is any oncoming traffic. When allowed to pass, sound the horn appropriately or turn on the width indicator lights; 3. Drive on the right: 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. No overtaking: Overtaking, reversing, making U-turns, or parking are not allowed inside the tunnel. If the vehicle breaks down, turn on the width indicator lights and tail lights, and try to move the vehicle outside the tunnel.
When driving long distances, I often encounter tunnels. The first priority is to turn on the low beams in advance to avoid blurred vision caused by sudden changes in light when entering or exiting. Before entering the tunnel, observe the speed limit signs, usually requiring slowing down to below 60 km/h, and maintain a greater distance from the vehicle ahead, leaving at least 50 meters of safe space. Never change lanes or overtake inside the tunnel, as the solid line areas are particularly prone to collisions. In case of a vehicle breakdown, immediately pull over to the right emergency lane, turn on the hazard lights, place a warning triangle 100 meters behind the vehicle, and quickly evacuate to the pedestrian walkway. When exiting the tunnel, don’t rush to accelerate, as the sudden bright light can make it difficult to see the road conditions clearly.
As a daily commuter, I think air conditioning settings are crucial. Switch to recirculation mode before entering tunnels to prevent exhaust fumes from entering the car. Also, turn down the radio volume slightly, as tunnel broadcasts might announce emergencies. It takes time for eyes to adjust to light changes, so I always grip the steering wheel firmly when entering or exiting tunnels. If traveling with elderly or children, be extra careful not to open windows - tunnel noise and echoes can easily startle passengers. If you notice the car ahead using high beams, simply use the anti-glare rearview mirror function instead of flashing lights to compete.
