Lansing Fire officials say at about 4:22 p.m. a Lansing School bus rear-ended a car, injuring four and sending at least three to Sparrow Hospital.
Six students and a driver were on the bus.
At least two students were sent to Sparrow Hospital for further observation and what officials believe is a broken leg for one of the students.
The driver of the rear-ended car had an infant secured in a baby seat, but according to Lansing Police she and the child are fine.
Lansing school officials say they drug test all bus drivers.
This is the second bus accident in as many weeks, but school officials say that trend is only a coincidence.
