Are you on the school bus?
JDon, do you mean: "can I drive by the school in my private vehicle on the road not entering the schoolgrounds with my handgun(s) and my valid LTCH?"

Seems to me if you are just driving through you should be fine. IANAL though so this is not official legal advice.
The only law that addresses that is the federal "gun free school zone" law, and an exception to that exists for those who hold a CCW/LTCH/permit/whatever from the state in which the school is located (or "recognized by the state in which...", I forget the exact phrasing. Since as an IN resident, you must hold a LTCH (or be a member of some excepted group) to have your gun with you, you would automatically be excepted from it yourself, unless you'd just purchased the gun and were on your way home.
In short, I think you'd be good in this situation.
