SINGAPORE - A lorry caught fire on the Ayer Rajah Expressway near the Normanton Park bus stop on Thursday morning.

Housewife Shilpi Banerjee, who lives on the second floor of a condominium nearby, said she heard shouts outside her home at around 11.30am.

"I ran to the window and saw flames roaring up from the carriage section of the open lorry," said Ms Shilpi, who is in her 40s.

The Singapore Civil Defence Force (SCDF) said it dispatched a fire engine, a red rhino and two fire bikes to the scene.

Firefighters equipped with a trio of compressed air foam backpacks and a water jet extinguished the fire.

No injuries were reported.

The cause of the fire is not yet known and investigations are ongoing, said the SCDF spokesman.

In a safety advisory, the SCDF said most vehicle fires occur while vehicles are travelling on the road, with primary cause often due to ignition sources such as overheating and electrical faults within the engine compartment.

It urged drivers to equip their vehicles with a fire extinguisher and should he or she spot signs of smoke coming from the vehicle, adopt these measures to minimise injury:

- Pull over safely to the side of the road,

- Turn off the ignition

- Evacuate everyone from the vehicle.
