THE tragic accident along Dunearn Road in February where three men died was due to the driver's reckless driving, said a coroner.

State Coroner Victor Yeo said it was fortuitous that the traffic was very light given that it happened in the early hours of the morning and no other vehicle was involved when the driver beat the red light at a high speed.

The Feb 10 accident left a fourth man with traumatic brain injury. The survivor, Mr Muhammad Alif Mohamed Shah, 20, whose older brother died in the accident, now needs supervision for his daily activities.
