Drunk Woman Drives her Drunker Boyfriend's Car and Gets Arrested

Around 2:17 AM on August 30, 2025, Sergeant Matthew Bast and Patrolman Connor English with the Lambertville Police Department were on patrol and observed a black 2019 Volkswagen Tiguan speeding 40 MPH in a 25 MPH zone on Route 165 while headed south. The vehicle was also operating without headlights. Sergeant Bast then made a U-turn and activated his emergency lights to initiate a traffic stop, as the driver continued south on Route 29. The driver pulled over on Route 29 southbound in the neighboring town of West Amwell.

They exited the patrol car and made contact with the driver, who was identified as Keirstin Betz. As the officers were speaking with Keirstin, they detected the odor of alcohol and observed indicators of impairment. She admitted to the officers that she was coming from a bar in New Hope, Pennsylvania. She also admitted to consuming 2 drinks earlier that evening. The owner the vehicle, later identified as Albert, happened to be in the backseat of the vehicle. It was evident that Albert was heavily intoxicated.

Based on his suspicion of impairment, Sergeant Bast asked Keirstin to exit the vehicle and perform field sobriety exercises. He started with the Horizontal Gaze Nystagmus (HGN) test. During the HGN test, Sergeant Bast observed the lack of smooth pursuit, distinct and sustained nystagmus at maximum deviation, and the onset of nystagmus prior to 45 degrees. The second exercise was the One Leg Stand test. She completely failed to follow instructions during the One Leg Stand test. The third exercise was the recitation of the alphabet from “A” to “Z,” which she did not do perfectly. The final exercise was the Walk and Turn test. During the Walk and Turn test, Keirstin failed to touch heel-to-toe on each step, turned improperly, and failed to keep her arms at her sides.

Based on her erratic driving, her admission to consuming alcohol earlier that evening, and her inability to satisfactorily perform the field sobriety exercises, Keirstin was placed under arrest for operating under the influence. Keirstin was transported to the Lambertville Police Department for further processing. Patrolman Tylor Switalski eventually transported Albert to the station to wait for her in the lobby. Albert’s vehicle was impounded for a 12-hour hold according to John’s Law.

At the station, Keirstin was read the Standard Statement for Motor Vehicle Operators, and agreed to submit breath samples. Her Alcotest results indicated a BAC level of 0.144%, which was nearly double the legal limit of 0.08%. After the Alcotest was complete, she was eventually released to her father pending her court appearance after he signed the Potential Liability Warning form on Keirstin’s behalf.

Keirstin was issued the following traffic tickets:

-Operating under the influence (39:4-50)

-Careless driving (39:4-97)

-Failure to use lighted lamps when required (39:3-47A)

Court records indicate that on November 6, 2025, Keristin was found guilty of operating under the influence and failure to use lighted lamps. As a result of her convictions, Keirstin had to use an ignition interlock device for 3 months, spend 12 hours at an intoxicated driver resource center, and pay a total of $790 in fines. The other citation for careless driving was dismissed as part of a plea agreement.
