Twenty-five years ago, a crash near Lentor Avenue left his car in flames.
He opened his door to escape. But the front passenger door was stuck, trapping his wife inside.
No one came to their aid. Fortunately, he managed to pull out his wife in time.
Since that close shave, he vowed to himself that if he were to come across a similar situation, he would step in to help.
His chance came yesterday as he was driving on the Bukit Timah Expressway (BKE) towards the Pan-Island Expressway at about 1.20pm.
The 53-year-old man, who wanted to be known only as Mr Lim, saw a car and a tipper truck colliding. Almost immediately, flames started shooting out of the car's bonnet.
Mr Lim, who is self-employed, said he stopped about 20m from the accident site. When he got out of his car, he saw that there was a couple inside the burning car.
He told The New Paper: "I shouted to the woman: 'Has anything happened? Can you wake up?' She opened her eyes, but didn't say anything."
He rushed over and managed to pull her out through her window, which had been broken by the tipper truck driver.
He carried her to safety.
