A 28-year-old who allegedly ran over a group of teenagers while allegedly more than four times the legal blood alcohol limit has admitted it was 'a mistake'.

Deng Manyoul was driving along Adelaide Street in Brisbane just after midnight.

He blew almost five times the legal alcohol limit, according to police.

He's accused of running over three teenagers, minutes earlier.

Nine News spoke exclusively to his shocked mother, who says she warned her son not to drink and drive.

Three 18-year-old friends were crossing at the intersection but police say Manyoul didn't stop, allegedly running the red light and knocking the trio over.

The 28-year-old Redbank Plains man should never have been behind the wheel.

He told 9News: “I didn't kill nobody.

“That was an accident. I was on the phone and I made a mistake. You made a mistake when you were drunk? The thing went green and then I moved.”

His mother had no idea her son had been charged. She says told him not to drink and drive.

“I tell him to be careful when you're driving. Don't drink because you're not allowed to drink and drive,” she said.

Manyoul's facing numerous charges, the most serious, dangerous operation of a vehicle while adversely affected.

He's been bailed and will front court after Anzac Day.
