I don't have links handy now but when we had 5'er and were thinking of double towing boat, I compared several of the ones Google found and there was lots of inconsistency in them for Georgia laws. Also, most did not agree with what a high ranking friend in State Patrol told me. So, keep in mind what you find online is "what the internet says" about the laws. Your best source but much more time consuming is to search for online version of the state's actual statutes. I use LexisNexis for Georgia searches...not sure if they have other states setup or not.
