At approximately 12:50 A.M. on July 4, 2015, a Ross Township police officer was observing traffic from a parking lot on McKnight Road in his marked police vehicle. He observed Appellant make an illegal U-turn on McKnight Road at Nelson Run Road. The officer pulled out of the parking lot onto McKnight Road and followed Appellant. He ran Appellant’s registration and while following Appellant observed that he twice swerved over the solid white line separating McKnight Road from the 279 South on-ramp. At that point, the officer activated his lights and sirens and attempted to conduct a traffic stop of Appellant’s vehicle. Appellant drove another 300 feet before pulling over in response to the police officer’s actions.
The officer walked over to the driver’s side window and spoke with Appellant. He immediately smelled a moderate odor of alcoholic beverage on Appellant’s breath. Appellant’s eyes were glassy, watery, and bloodshot. Appellant provided his driver’s license upon request, and the officer returned to his vehicle to run Appellant’s license. He learned that Appellant’s driver’s license was suspended.
When he returned to Appellant’s vehicle, he noticed that the vehicle was still in drive, and he requested that Appellant shut the vehicle off and hand him the keys. Additional officers arrived on the scene to serve as backup, and the officer asked Appellant to step out of the vehicle to conduct field sobriety tests; Appellant complied. The officer administered several field sobriety tests, including walk and turn, one leg stand, and modified Romberg balance tests. Appellant swayed throughout the tests and had difficulty following instructions. Appellant failed the walk and turn test and the one leg stand test. At that point, the officer asked Appellant to submit to a preliminary breath test, and Appellant complied. Appellant admitted that he was drinking earlier in the evening.
