All speed limits are set via permit, through the Department of Transportation. Since this street is under 500 feet long (384' roughly) a speed limit is not assigned to this road. Please see the provided link for some FAQ from DOT regarding speed (https://www.ct.gov/dot/lib/dot/documents/dstc/speed_limits_faq.pdf) At this time I cannot post a speed limit on your roadway. Since this is a small roadway with very few houses, if you could provide me with an offender address it is possible that the police department may send an officer out to speak to them in efforts to slow them down. Thank you.
