The former bus driver says MTD told him there could have been someone behind the snowman or something inside it.
But the bus driver says he saw two cars almost crash. In a snap decision, he decided to run it over.
The viral video of the event has gotten over 10,000 hits since it was posted Saturday.
You can see cars swerving around the snowman on the icy roads.
The bus driver says he passed through that street several times that day and saw kids making it.
He was afraid someone would get into an accident and decided to get it out of the way.
The MTD wouldn't comment on the event.
