LANHAM, Md. (CBSDC)- Mayor Vincent C. Gray signed two new bills this morning that will enhance impaired driving enforcement in the District.

According to the Mayor’s office, the bill-signing ceremony culminates a two-year effort by his administration to toughen impaired driving laws, develop an advanced program for breath testing and improve enforcement and prosecution.

The newly signed bills complement a 2012 law, effective as of August 1, that raised maximum penalties for some impaired drivers.

One of the new provisions being signed into law allows the courts to require some first offenders in impaired-driving cases to use ignition-interlock devices.
