An analysis of school bus crash data shows that more than four buses a day in metro Atlanta are involved in minor to major accidents.

Cobb County schools reported 276 crashes in 2014, 195 crashes in 2015 and 157 so far this year.

The Atlanta Journal-Constitution found in a review of bus crash data that some districts do not fully report the number of accidents. That is important because without the data the state Department of Education has a harder time tracking safety issues, bad drivers and prepare training.
