“RHOC” star Shannon Beador was zooming around a residential street moments before slamming her car into the side of a house … according to this insane footage of her alleged DUI incident.

Beador was hightailing it around a Newport Beach, CA street on Saturday just before midnight, when — based on this video — she seemed to misjudge a corner, careen out of control and crash into the home. .

Almost immediately, Beador threw her car in reverse, getting off the sidewalk and back onto the street before slowly pulling away.

We got these pics of the damage left behind from the accident … a concrete planter is crumbled after taking the brunt of the impact and there’s a huge skid mark on the road.

It also looks like Beador barely missed the front door of the house … which likely would’ve caused even more damage, and potentially injured someone inside the home.

TMZ broke the story … sources say Beador eventually parked in the middle of the street, getting out with her dog. We’re told when cops arrived, she tried to act like she was just walking her pup, but the officers weren’t buying it.

A rep for Newport Beach PD says Shannon was arrested and booked for hit-and-run and DUI alcohol — both misdemeanors — and was cited and released without bond.

The Bravo series isn’t currently in production, so she wasn’t filming before the arrest — her lawyer Michael Fell says, “[Beador] is extremely apologetic and remorseful. We will be awaiting the official information on this case as it becomes available, and Shannon is prepared to accept full responsibility for her actions.”
