KUALA LUMPUR (June 14): There is no indication of mechanical failure or excessive wear in the braking, steering and suspension systems of the bus involved in the fatal crash involving Sultan Idris Education University (UPSI) students in Gerik, Perak, said the Ministry of Transport (MOT).

In a statement, the MOT said, "There is no evidence of mechanical system failure leading to the accident." 

The tyres also have adequate tread depth and comply with regulatory standards, the MOT said following an initial technical report by the Computerised Vehicle Inspection Centre (Puspakom). 

"Therefore, it is highly likely that the accident resulted from other factors — such as human error, road conditions, and so on," the ministry said. 

Heavy vehicles also typically deploy engine braking involving compression release engine brake which utilises air compression using energy from the engine's rotation to slow down. Commercial vehicles are required to undergo routine inspection by approved motor vehicle inspection bodies, such as Puspakom, every six months. 

In the statement, the ministry said the assessment covered the braking system, including brake linings, brake drums on every axle, tyres, steering components, and suspension components. 

All are either in satisfactory condition without excessive wear or mechanical failure, the statement read. 

"Appropriate improvement measures will be considered and implemented based on the final findings to ensure continued enhancement of road safety.

"The MOT underscores that road user safety is our top priority. 

"Enforcement of safety standards compliance, driver qualification, and monitoring of transport company operations will be continuously strengthened," the ministry said.

"To all families of the victims, the MOT extends its condolences and is committed to ensuring justice is served and that such tragedies do not recur," it added. 

At 1am on June 9, a crash occurred along the East-West Highway involving a tour bus carrying 42 UPSI students and a Perodua Alza carrying a family of four. 

The bus, travelling from Jerteh, Terengganu to UPSI's main campus in Tanjung Malim, Perak, crashed sideways, resulting in 15 deaths, while 33 others were injured. 

On Friday, the bus driver, Mohd Amirul Fadhil Zulkifli, 39, pleaded not guilty to 15 counts of dangerous driving in the Magistrate Court located in Gerik. 

Of the 15 charges, 14 fall under Section 41(1) of the Road Transport Act 1987 for causing death by dangerous driving, which carries a maximum penalty of 10 years' jail and a fine of up to RM50,000 upon conviction.

The other falls under Section 42(1) of the same Act for reckless and dangerous driving, which carries up to five years' jail, or a fine of at least RM5,000, or both. Both sets of charges allow for axeing of driving licence for at least five years.
