32 CFR § 634.31 - Parking.

(a) The most efficient use of existing on- and off-street parking space should be stressed on a nonreserved (first-come, first-served) basis.

(b) Reserved parking facilities should be designated as parking by permit or numerically by category of eligible parkers. Designation of parking spaces by name, grade, rank, or title should be avoided.

(c) Illegal parking contributes to congestion and slows traffic flow on an installation. Strong enforcement of parking restrictions results in better use of available parking facilities and eliminates conditions causing traffic accidents.

(d) The “Denver boot” device is authorized for use as a technique to assist in the enforcement of parking violations where immobilization of the POV is necessary for safety. Under no circumstances should the device be used to punish or “teach a lesson” to violators. Booting should not be used if other reasonably effective but less restrictive means of enforcement (such as warnings, ticketing, reprimands, revocations, or suspensions of on-post driving privileges) are available. Procedures for booting must be developed as follows:

(1) Local standing operating procedures (SOPs) must be developed to control the discretion of enforcers and limit booting to specific offenses. SOPs should focus on specific reasons for booting, such as immobilization of unsafe, uninspected, or unregistered vehicles or compelling the presence of repeat offenders. All parking violations must be clearly outlined in the installation traffic code.

(2) Drivers should be placed on notice that particular violations or multiple violations may result in booting. Also, drivers must be provided with a prompt hearing and an opportunity to obtain the release of their property.

(3) To limit liability, drivers must be warned when a boot is attached to their vehicle and instructed how to have the boot removed without damaging the vehicle.
