A bus driver who negligently drove into a low bridge in Melbourne, seriously injuring six passengers, has been jailed for more than five years.

Family members and loved ones of Ballarat bus driver Jack Aston, 55, wept as he was sentenced in the County Court on Monday.

The Gold Bus driver displayed "flagrant inattention" when he crashed into the Montague Street bridge in February 2016, failing to notice any warning signs or the upcoming bridge.

Six of his 14 passengers suffered a range of serious injuries including spine fractures, glass particles in the face, scalp injuries and neck fractures.
