The scales of justice may not tip in her favor.

A South Carolina woman hurled a live snake into a car to scare off the driver, and then took the vehicle on a wild ride until cops arrested her, authorities said.

Hilmary Moreno-Berrios, 29, allegedly swung wooden sticks at the unnamed female driver and then tossed a black snake at her in an attempt to steal the woman’s silver Honda CR-V in Greenville on Friday night, according to cops.

Moreno-Berrios took the SUV from the victim and sped off — with the snake along for the ride.

Surveillance footage released by cops captured an out-of-control Moreno-Berrios barreling down the area’s Main Street and plowing into event barriers that were set up for a pole-vaulting competition.

Bystanders can be seen in the video running for their lives as Moreno-Berrios recklessly drives the SUV through the area.

Moreno-Berrios was nabbed a short time later by officers with the Greenville Police Department after she struck a moving vehicle holding a mother and daughter in an attempt to flee, cops said.

The collision disabled the SUV — and miraculously, no one was killed.

Moreno-Berrios was taken into custody and brought to a local hospital for an injured shoulder.

She ultimately was charged with carjacking, malicious damage to personal property and five moving violations.

The suspect caused about $17,225 worth of damage to the pole-vaulting site, police said.

The snake, which was non-venomous, was released back into the woods by cops, authorities said.
