A post-crash inspection found that the vehicle’s brakes, tyres, steering, and suspension were all in good condition and met safety standards.

“Based on observations and the technical investigation, there was no evidence of mechanical system failure that could have caused the accident.

“Therefore, it is highly likely that the accident was caused by other factors such as human error, road conditions, or similar external factors,” the investigators said in the report.

The report said the air brakes of the bus were in satisfactory physical condition, without any sign of excessive wear. The air compressor tank was also intact without any leaks identified.

It said two sets of leaf springs and shock absorbers were found to be faulty but it might be a result of the crash.

The bus sustained major structural damage in the crash, including a crushed front end, shattered windows, broken support pillars, and severe body panel deformation.

The report also said the bus underwent its last inspection before the accident on April 13 at Puspakom’s Kota Bharu centre, where it was given a “pass”.

Transport minister Loke Siew Fook said appropriate measures will be implemented by the ministry based on the final findings to ensure road safety.

“Meanwhile, enforcement of compliance with safety standards set by the ministry, driver’s qualifications, and the monitoring of the transport company’s operations will continue to be tightened.

“The ministry expresses its deepest condolences to the victims’ families, and it is committed to ensure that such tragedies do not recur,” he said in a statement.
