10:55 AM PT -- Peter Thomas has broken his silence on his recent arrest ... taking full responsibility for what went down last week.

In the clip, filmed from a plane and posted on his Instagram Friday, Peter says his phone has been blowing up and wanted to address the incident -- claiming he refused to blow for a breathalyzer test during the ordeal, and was in the hospital due to his high blood pressure.

"I REFUSED TO BLOW"

He says he willingly turned himself in, and it was a quick process ... thanking the Cobb County Police Department for how they handled the whole thing.

Cynthia Bailey's ex-husband, Peter Thomas, has been arrested for DUI, TMZ has confirmed ... after allegedly weaving between lanes and flying through a red light.

According to the docs, obtained by TMZ, officers in Atlanta say they spotted Peter weaving without tags on his SUV last week, so they followed him -- claiming he blew through a red light after exiting the interstate.

PD then pulled him over, and said they detected "a strong odor of an alcoholic beverage" coming from his car ... and said Peter had "watery, glassy, and bloodshot eyes."

They initially brought him to Cobb Adult Detention Center, but he was denied due to blood pressure ... so he was brought back to the hospital and was left with staff -- what a night.
