The term PART OF MADD is solved by the seven-letter word AGAINST. Mothers AGAINST Drunk Driving (MADD) is a non-profit organization in the United States and Canada that seeks to stop drunk driving, support those affected by drunk driving, prevent underage drinking, and strive for stricter impaired driving policy. The organization works to achieve its goals through public awareness campaigns, victim services, and legislative advocacy. By using the word AGAINST, it is clear that MADD is actively working AGAINST drunk driving and other related issues.
