A fatal school bus crash in Walnut Tuesday is an important reminder of the need for caution when it comes to buses.

A driver was killed and eight children were injured after a school bus rolled over in northern Mississippi. The crash did not involve another vehicle, and appears to have been caused when the driver suffered a medical emergency.

Benton County Coroner Larry Hobson said the driver, 63-year-old Chester Cole, appeared to his clutch his chest and slumped over in his seat before the crash, The Associated Press reported.

Eight injured children were taken to Le Bonheur Children’s Hospital in Memphis.

Though a crash like this is rare — and wasn’t caused by another vehicle — motorists should remember to be careful when sharing the road with buses.

Give them plenty of room — students may not be paying attention to traffic when they get off a bus. Below are a few more rules to keep in mind regarding school buses:

• Never pass a bus if it is stopped to load or unload children.

• Traffic must stop if the buses flashing light or “stop” arm is extended.

• Always be alert to children approaching a stopped bus.

• Be aware that some streets near schools may close or have reduced speed limits during school hours.
