lowering a speed limit by 10 mph would decrease accidents but it's not necessarily the case. Here is the DOT's own study on this: http://www.ibiblio.org/rdu/sl-irrel.html

I've read through the report cited, here are a few things I noted:
1) It is a single 21 year old study
2) The information on the page linked is extracted from the full 84 page DOT study by a group called Reasonable Drivers Unanimous. You have to fill out a questionnaire to enter RDU's website, so I'm going to take a leap of faith that they could also be called Fast Drivers Unanimous
3) Even the one page they chose to publish is inconclusive. For example, if the speed limit is lowered, the slowest drivers actually increase their speed by 1 mph. Which means, when all traffic moves at the rate of the slowest driver, lowering the speed limit actually increases your real time driving speed.
