Depending on the geographic region dedicated ambulances were typically rare. In small towns and rural areas the local undertaker often provided ambulance service using the hearse.
Think how far ambulances have come with the life saving services they can provide now. Growing up in Chicago I well remember the 1957 Cadillac based ambos whose attendants could only provide rudimentary first aid at best. I can't recall, but as the Caddys were taken out of service the city must have purchased van based ambulances.
