THE Land Transport Authority has confirmed it is conducting an internal investigation to determine the cause of the bus accident involving about 35 students yesterday.
"We are still progressing with our internal investigation and once we have completed (that), we will give the finding to the relevant authority which is the police," authority spokesman Iliesa Sokia said.
Mr Sokia said it was too early to determine what might have caused the accident. As far as the safety of the buses were concerned, he said they were trying to address the issue.
"The LTA has done a lot in trying to address the safety of buses. The establishment of the Quality Assurance Maintenance System or QAMS is an LTA initiative to help guide the bus operator, bus drivers and mechanics on how to go about carrying out maintenance on a daily basis.
"QAMS is what they have to do every day on their buses, mechanically, electrically and the whole maintenance work. We make it easy for them and it's so simple that you don't have to be a mechanic to do it, a driver can simply go through it and do the maintenance independently.
"It also involves routine maintenance or major maintenance. So when these buses come for their six months or one year fitness test, we expect them to meet and comply with LTA standards."
Mr Sokia said the bus operators should not expect LTA to identify defect for them when they come for fitness.
"LTA is there to ensure they meet the standard and comply with the standard. The removal of defect is the responsibility of the bus operator through the QAMS."
