People will need to drive slower around Rutland Middle School and Rutland High School.
County officials said Wednesday that new 25 mph speed limits are in effect around the schools along Skipper Road during certain school hours. The old speed limit was 45 mph.
Legally, the zones run from 1,000 feet south of Hartley Bridge Road to 500 feet north of Farwell Street.
The Bibb County Board of Commissioners approved the new speed limits last week.
