Montgomery County Executive Ike Leggett rolled out another effort to curb the number of pedestrian deaths Monday with a series of public service announcements and videos that include emotional testimonies from mothers who lost children to car accidents.

The 30-second commercials — which will air on the county cable channel — and longer videos — which will be available in high schools and adult learning centers — are part of an ongoing effort by Leggett to reduce the number of collisions between cars and pedestrians in the county.
