hot line, a means of contacting a trained counselor or specific agency for help with a particular problem, such as a rape hot line or a battered child hot line. The person needing help calls a telephone number and speaks to a counselor, who remains anonymous and who offers emotional support, specific recommendations for action, and referral to other medical, social, or community services. Such services are usually maintained by volunteers and are accessible 24 hours a day, 7 days a week.
