NSW bus driver disqualified from driving

A bus driver has apologised outside court for steering into the path of a semi-trailer on Sydney's busy M5 motorway with 23 children on board.

Kazem Afkhamisaddoghi, 60, cannot hold a licence for two years and will need a medical clearance if he ever reapplies following his conviction for dangerous driving in Liverpool Local Court on Wednesday.

Footage of the incident in June showed the school bus pulling off a service road into the path of the semi, before the truck jack-knifed in a cloud of white smoke.

The bus driver's solicitor said his client's limited English meant he misunderstood GPS instructions and drove onto an off-ramp for a weighbridge and the tolling authority's building.

When he realised his mistake, he went back the way he'd come before trying to re-enter the peak hour traffic at the start of the off-ramp.

The court heard Afkhamisaddoghi lost his job over the incident before completing a traffic offender program.

Outside court, he wiped his eyes as he told reporters he was sorry for the crash.
