|(a) All vehicles utilizing open parking must display a current parking permit. Up to two permits may be issued to each employee, but only one vehicle bearing a permit issued to an employee may make use of that employee's parking privilege within the Capitol Complex at a time. The department is authorized to issue either decal permits or hanging permits. (1) Decal permits shall be applied to the vehicle according to instructions provided at the time of issuance. (2) Hanging permits will normally be hung from the rearview mirror when the vehicle is parked in a state parking lot or garage. If no mirror post is available, the permit may be taped to the front windshield, in the lower center, or otherwise displayed so that it is readily visible from outside the vehicle. If hanging permits are issued, one permit will be issued to each eligible employee. The employee may use the hanging permit on any vehicle which the employee drives to work. (b) An employee who is issued a permit will be responsible for any parking violations on vehicles bearing the permit. (c) Employees with unpaid charges recorded in their name shall be ineligible to receive a parking permit while such charges remain unpaid. (d) All permits will expire and be renewed on a biennial basis. (e) Parking permits may be used only by the employee the permit is assigned to and may not be loaned or allowed to be used for any purpose other than for parking of a state employee's vehicle while the employee is at work within the Capitol Complex.
