Revise DUI laws regarding actual physical control

This bill clarifies Montana's definition of "actual physical control" under DUI laws, specifically excluding certain non-driving scenarios from DUI charges. It states that a person is not in "actual physical control" if seated in a passenger seat with the engine running but not in gear, if the vehicle is disabled (not from a collision), or if manually pushing a disabled vehicle. This directly affects individuals stopped in vehicles under these specific conditions who might otherwise face DUI charges. The amendment does not change DUI penalties, alcohol limits, or other legal standards - it only refines the definition of when a DUI charge applies.
