A safe haven for late-night revellers who are vulnerable, drunk or under the influence of drugs is being unveiled.
The new SOS bus, which will operate on Friday and Saturday nights around Medway, has vital life-saving equipment including oxygen and a defibrillator.
Kent Police, NHS Medway and Medway Council are all involved in the scheme.
Insp Gary Woodward said advice and assistance would also be on offer, and people would be helped in a "positive and non-judgmental way".
The bus will be staffed at night by volunteers, including qualified medical personnel from St John Ambulance, while during the day Medway's Public Health Team will use it as a mobile setting for health promotion.
The mayor and mayoress of Medway will unveil the bus at an event in Rochester later on Tuesday.
