About the Digest of Motor Laws
The Digest of Motor Laws was first published in 1930 and endured in print through 76 editions. During these nearly eight decades, the Digest grew from a modest pamphlet to a more than 700-page compendium of motor vehicle and traffic safety laws of the 50 states, territories, and the provinces of Canada aiding motorists, law enforcement, policy makers and others. The 2010 edition was the last paper version of the book produced and in 2011, the publication was transitioned online.
The content on this website is prepared from information compiled from state statutes and regulations as well as submissions from local and state jurisdictions to AAA. For each state, territory, or province, the Digest covers general interest subjects on private passenger vehicles. Some limited coverage of laws governing commercial vehicles is included, as are some special laws relating to motorcycles, mopeds, and trailers.
While AAA makes every effort to provide accurate and complete information, AAA makes no warranty, expressed or implied, and assumes no legal liability or responsibility for the accuracy or completeness of any information contained herein.
