Baltimore County police were warning motorists in the central Towson and Lutherville areas Wednesday of a number of traffic lights that were out, though some began to come back on after noon.
Police said motorists should use extreme caution at intersections where a traffic signal has malfunctioned.
Police spokesman Cpl. John Wachter said BGE has been contacted about the issue. "We are suspecting a problem with a transformer at York and West roads may have caused the outage."
Around noon the BGE website reported 14 outages in the area, but the cause was still being investigated.
