Each privacy room prevents access to liquids or other substances which can be used to substitute for or adulterate a donor's urine specimen. The collection site person is at a station (20) that is near a supply of containers, a secure receptacle (18) for temporary locked storage of filled containers and special outer garment and valuable article storage areas (24, 26). The vehicle may be towed as a trailer or self-powered and does not require external permanent water supply or drain connections.
