A vehicle equipped with an operator presence detector comprises an optional first detector located and configured to detect an object positioned over a threshold to the operator compartment; a second detector located and configured to detect an operator's left lower extremity when the left lower extremity is located in the operator compartment; and a third detector located and configured to detect an operator's right lower extremity when the right lower extremity is located in the operator compartment. The second detector and the third detector are positioned such that (i) an operator cannot use the left lower extremity to trigger both the second detector and the third detector and (ii) an operator cannot use the right lower extremity to trigger both the second detector and the third detector.
