CCTV of near miss where a truck almost slammed into a school bus

The driver of the truck that miraculously avoided plowing into the back of a school bus carrying 20 school girls is being hailed a hero after his quick thinking prevented a catastrophic pile up on Sydney's M5 motorway.
Daniel O'Sullivan, who was driving just metres behind the truck, has revealed his initial panic when spotting the bus load of school children suddenly pull in front of the 22 tonne semitrailer that was travelling at 100km/h.
'I expected carnage on the road, I expected a catastrophic event,' he revealed to 9 News.
'I could observe children in the bus, I expected they'd be severely injured if not killed.'
The witness also pointed out that it appeared as if the bus driver had no intention to stop the bus following the incident.
'I put my car in front of the bus and slowed him down and a truck driver observed what i was doing and we herded him into the help point area,' he added.
Kazem Afkhamisaddoghi has since apologised for the frightening near-miss at around 8am on Thursday morning.
CCTV footage released by police shows the bus allegedly pulling out in front of a semi-trailer on the busy motorway at Hammondville during the Thursday morning school run.
The truck driver, Daryl Wilson brakes heavily causing his vehicle to jack-knife in order to avoid a collision.
The driver told 7NEWS: 'I'm very, very sorry about this.
'I don't know how I can to say it because my English language is not very good and I can't say all the words in my heart.'
The 60-year-old also praised the quick-thinking of the truck driver.
A student on the bus spoke to Daily Mail Australia about the horrifying near-crash.
'We were going to West Hoxton for an AFL gala day. We were on the M5 to begin with and then the bus pulled off to the side,' she said.
'He was halfway into the furthermost lane and then realised that was the wrong lane to be in so he decided to go back onto the M5.
