ADAMS TWP — Police last week charged a Valencia man with failing to install an ignition interlock system as a condition of his prior drunken driving arrest.

Adams Township police said they stopped 50-year-old Curtis W. Keyser’s Toyota Corolla after suspecting he was impaired while driving on Three Degree Road about 10:35 p.m. March 7.

Patrolman Edward Lenz when he approached the car to speak with Keyser smelled marijuana coming from the vehicle, according to court documents.

The officer checked the suspect’s license that showed he was not allowed to drive a vehicle without an ignition interlock device, police said.

The interlock system requires a driver on a restricted license to blow into a tube that detects the presence of alcohol in the breath.

The device blocks a vehicle’s engine from starting if the driver has alcohol on his breath.

Lenz looked inside the car but could not find the device. Keyser claimed the car had one, and pointed to a coiled-up cord that appeared to run toward the glove box.

The officer followed the cord, court documents said, but found it was actually a cell phone charger with a cell phone at the other end.

A search of the defendant, police said, turned up in a coat pocket a film container with suspected marijuana inside. A metal smoking pipe was in the same pocket.

Police Friday charged Keyser with driving without an ignition interlock, and possession of a small amount of marijuana and drug paraphernalia.

Driving without an interlock device is a misdemeanor and carries a maximum penalty of 90 days in jail and a $1,000 fine.

A preliminary hearing is set for April 24 at the office of District Judge Wayne Seibel in Evans City.
