GAITHERSBURG, MD — In an effort to curb impaired driving and underage drinking, law enforcement officials will be conducting a sobriety checkpoint Saturday night.

Montgomery County Police will open the checkpoint around 10 p.m., weather permitting. Officials do not disclose checkpoint locations in advance.

In 2015, Montgomery County Police Officer Noah Leotta was killed when he was hit by a repeat drunk driver while working on the alcohol task force. As a result, state law now requires ignition interlocks to all drunken driving offenders in Maryland.
