• The round trip distance traveled is less than 100 miles
• The round trip distance is more than 100 miles and a motor pool vehicle is requested, but is not available.
• Use of a motor pool vehicle is not possible or not feasible (i.e. faculty or staff members are located in an area not served by campus motor pools).
