Bus drivers from across the state rallied at the steps of Melbourne's Parliament House to support Ballarat's Jack Aston on Sunday.
Organised by his family, supporters from as far away as Echuca came down, and buses decked out with messages circled the block.
The Ballarat Gold Bus driver crashed into a low clearance bridge on Montague Street in South Melbourne in February 2016 and was found guilty of six counts of negligently causing serious injury.
While his appeal is within the month, Mr Aston's wife and daughter said they were grateful for the support.
"It tells you that people want to stand up, it's an everyday person going to work," his wife Wendy said - she's counting down the days until the appeal.
"They feel, I think, we're just normal people, it could happen to everybody."
She added Mr Aston rang from prison during the rally, and said he was excited to hear the support.
"I've met up with bus drivers he's known, so I could say I ran into this one and that one, it's nice for him to have those connections," she said.
Mr Aston's daughter Meg agreed - she said she was surprised at the large turnout.
"It makes him feel supported, and we're supported as well," she said.
"(There were) a lot of bus drivers in their uniforms, they're people getting behind my Dad.
"We had some amazing signs made today, and it'd be good to get a few people standing out the front of the courthouse for the appeal."
The appeal is set for October 7.
Mr Aston was jailed on December 17.
