32 CFR § 634.50 - Towing and storage.

(a) Impounded POVs may be towed and stored by either the Services and DLA or a contracted wrecker service depending on availability of towing services and the local commander's preference.

(b) The installation commander will designate an enclosed area on the installation that can be secured by lock and key for an impound lot to be used by the military or civilian wrecker service. An approved impoundment area belonging to the contracted wrecker service may also be used provided the area assures adequate accountability and security of towed vehicles. One set of keys to the enclosed area will be maintained by the installation law enforcement officer or designated individual.

(c) Temporary impoundment and towing of POVs for violations of the installation traffic code or involvement in criminal activities will be accomplished under the direct supervision of law enforcement personnel.
