The Owner-Operator Independent Drivers Association (OOIDA) is an international trade association established in 1973. It represents the interests of independent owner-operators, professional drivers, and small truck fleets across the U.S. and Canada, boasting over 150,000 members who collectively operate more than 240,000 heavy-duty trucks. OOIDA was founded in response to the challenges faced by truckers during the 1970s oil embargo, and it has since grown into the largest organization advocating for truckers' rights. OOIDA engages in advocacy, legal support, and resources specifically designed for owner-operators and professional drivers. The association actively participates in policy discussions, rulemaking, and hearings on trucking issues, achieving significant victories over the years, such as the establishment of truth-in-leasing regulations and the abolition of discriminatory practices in the industry. OOIDA also offers truck insurance products and works to create a fair business environment for its members, focusing on issues like safety, leasing, and taxation.
