1) We have posted multiple speed limit signs and continually remind our members that the more they speed the higher the maintenance costs will be. For the most part, our members respect the limit.
Our problem is with USPS, FedEx, and UPS. We have stopped drivers and spoken to them directly, and called their supervisors to report speeding. These methods have not provided results.
2) Absolutely
3) I foresee many angles legislation could go as well the the problems they may cause. I got this idea from the bill that was passed a few years ago that allowed law enforcement jurisdiction over the roads on the Brunswick Navy Base, after it's closure, even though they were considered private property. Perhaps something similar could be done for road associations?
Another direction would be to give the association some kind of authority to fine speeders, whether they are members or not. Guests, visitors, service providers, etc. may abide by the posted limit if they know they could be fined. It would probably be very difficult to get something like this passed since large companies like USPS, FedEx, and UPS would lobby against it, but it would serve as a good tool to open up the discussion and perhaps get them to come to some agreement to respect road association speed limit signs.
