As on most days, Mr Kalai Chanthiran was using the Ayer Rajah Expressway (AYE) to get home to Johor on Wednesday morning.
The Malaysian had just finished his shift as an auxiliary police officer and he was in good time to get to the Tuas Checkpoint.
But this morning was different.
The first sign that something was not right was a traffic jam on the expressway, which almost never happens at that time - about 8.50am - in that direction, towards Tuas.
As he inched his motorcycle forward, he saw the cause - a tipper truck had toppled onto a taxi, spilling much of its cargo across the three lanes.
Beneath it, the taxi was a mangled wreck.
The 32-year-old would soon become one of the many unsung heroes who did their part to save the two men trapped inside the taxi.
He told The New Paper on Friday: "I quickly stopped my bike at the side and ran to help. Five or six people were already there, using their bare hands to scoop the truck's contents from the taxi."
The mess looked like damp cement, but he could also see pieces of concrete and broken tiles, much like construction rubble.
"We managed to clear off some of the debris so the driver inside could get fresh air," Mr Kalai said.
