Tunnel safety: what you should and shouldn’t do when driving in a tunnel

The Marina Coastal Expressway.

When you enter a tunnel, there are a few things you need to be aware of.

There are some safety procedures that, in the event of an emergency, could prove extremely helpful.

In total, there are 14 expressways and tunnels in Singapore.

In the event of an incident, the Expressway Monitoring Advisory System (EMAS) is activated.

Emergency crews will be directed to the scene of the incident and help to clear it as quickly as possible and restore traffic flow.

As tunnels are “confined spaces”, do drive carefully and observe safety signs.

According to LTA’s rules, when you’re driving in a road tunnel, do:

1. Tune in to a local radio station
2. Plan your route
3. Turn on headlights
4. Follow traffic signs
5. Stay in lane
6. Insert your stored value card into the IU in advance
7. Ensure your vehicle has enough fuel
8. Secure all goods safely
9. Keep left, if you are driving a heavy vehicle
10. Keep to the speed limit
11. Stow cranes on heavy vehicles before entering tunnels

When in a tunnel, do not:

1. Overtake or tailgate
2. Stop unless it is an emergency
3. Reverse your vehicle
4. Drive on the road shoulder
5. Drop off passengers or alight from your vehicle
6. Repair your vehicle or change tyres
7. Attempt to refuel your vehicle

LTA’s Operations Control  Centre monitors the road tunnels in Singapore.

In the event of a fire, ventilation systems will activate, and in the MCE, Woodsville and Sentosa Gateway tunnels, sprinkler systems will come on.
