If an object falls from your car onto the expressway, pull over to the shoulder of the expressway and report it using the emergency telephone or dialing the road emergency number #9910. When calling, report where and what fell onto the road.

4. I saw a car driving in the wrong direction!

If you notice an oncoming car driving in the wrong direction, first pull over to a safe location on the shoulder of the expressway to avoid a collision. Next, report the incident by calling 110 or the road emergency number (#9910), or dialing the emergency telephone.

Cars driving in the wrong direction tend to drive in the passing lane. If you notice information displayed on the variable information board, etc., about a Car driving in the wrong direction, slowdown and ensure enough space between the vehicle in front of you while you drive as close to the left hand side of the expressway as possible.

5. There was an earthquake!

If an earthquake occurs, gradually slowdown and stop on the shoulder. Afterwards, follow the instructions of JB HSBE or the police and evacuate to a safe location.

When leaving your car behind, turn off the engine and leave the keys in the ignition. Close the windows fully, but do not lock the doors.

Be very careful of other cars driving by as you get in and out of your car.

6. There is a fire in the tunnel!

*For Maiko Tunnel (approx. 3km), in case of a fire inside the tunnel, evacuation orders will be broadcast over the radio. If you are inside the tunnel, please listen to your radio.

(ⅰ) If you are in front of tunnel's entrance

If there is a fire inside the tunnel, driver's will be notified using the information board in front of the tunnel's entrance. If the information board indicates "進入禁止(No entry)" or "火災(Fire)," etc., do not proceed into the tunnel; instead stop at the entrance and turn on your hazard lights.

(ⅱ) If you are inside the tunnel and near the site of the fire

1. Ensure your own safety

If you see or detect a fire, turn on your hazard lights and immediately stop your car.

Be sure to stop your car on the far left side of the road (in some cases the far right) in order to ensure enough space for fire trucks to pass. When leaving your vehicle, turn off the engine and with the keys in the ignition, fully close all windows, but leave the doors unlocked.

After stopping your car, evacuate heading toward the exit or emergency exit in the opposition direction of the fire following the direction display board or emergency exit indicating lamp, while paying attention to safety to avoid being hit by passing cars.

Smoke from the fire will rise and accumulate at the ceiling before dropping down. To avoid smoke inhalation, use a handkerchief or something else to cover your mouth as you evacuate while maintaining a posture low to the ground.
