The Marietta police are warning drivers of back-to-school activity that may affect many drivers' regular commutes.

"Expect traffic congestion around the schools as everyone adjusts to the alterations in traffic movement," Marietta police said in a statement on Monday.

The city of Marietta starts the school year on Wednesday. Cobb County schools started classes on Monday.

Police also advised motorists to use "extreme caution" around school buses and obey speed limits in school zones.

When a school bus stops and flashes its signals, all traffic in both directions must come to a halt, according to Georgia law.

Marietta is only of several Georgia school districts that equips its school buses with cameras to catch violators.
