As with many crashes like with the school bus near Hereford High School Wednesday afternoon, there are still so many questions the day after.
While the 65 year old driver, Bonnie Faye Pessaro is still in the hospital with the most serious injuries, nine of the 40 or more middle and high school children on the bus yesterday were treated with just bumps and bruises.
It could have been worse, but it will be a while before we find out why it happened at all.
"The crash team investigation is going to be very detailed. They have a lot of measurements to do, interviews to do, a lot of computations to do... that usually takes several weeks," Baltimore County Police Cpl. John Wachter said.
Baltimore County police say they will be looking at both a possible mechanical cause, driver error or health.
What police do know at this point, is the bus was traveling north on York Road when it crossed into southbound traffic and hit a utility pole before rolling over on its side.
It is a scene not unlike a test performed by ABC News back in November.

Last fall, the administrator of the National Highway Traffic Safety Administration came out hard for seatbelts on all school buses nationwide.
It is a change in position for the feds.
