10 MPH

Posted at multiple locations on residential alleys in Baltimore County. I'm sure these were posted due to complaints. Any other agencies using super low speed limits (on white background) on public roads?

Hairpin turn on MA 2 (I believe speed limit 15, but I'm not sure)

The gravel road I grew up on in rural Oklahoma had a 15 mph speed limit. At the time, it was the only sign on the road other than the stop sign. (It has since gotten full street signs and a coat of asphalt, but no bump in the speed limit.)

The lowest I've seen is only in parking lots, which I don't think count here. I've seen an advisory speed limit for a sharp 90-degree turn that listed 15 MPH.

I don't see an issue with such low speed limits on alleys.  Default speed limit on Minneapolis, MN alleys (usually not signed) is also 10 MPH.

Definitely no issue, just curious to see them signed. There are around 600 miles of alleys in Baltimore City, not to mention the county, so signing them all would probably be expensive.

There's a street in Rome with a speed limit of 10: http://goo.gl/maps/N7kND

Yaleville Rd in St. Lawrence County has an advisory speed of 5 around one curve.

I thought you meant the one in Italy, until I clicked the link...

You are correct sir.  The Hairpin Turn on MA 2 does have a regulatory speed limit of 15 mph.

The access road to Walsingham Park in Pinellas County, Florida is posted at 10 MPH:

There's a strip mall (Redstone Plaza) off of MA 28 in Stoneham that has speed limit signs reading "SPEED LIMIT 5-10 MPH".  And, no, there's never been either a Woolworths or a Ben Franklin located there.

Not a public road, sadly, but the Disneyland parking lot had a speed limit of 14.

Lowest I've ever seen is 20. WSDOT doesn't allow speed limits below 20. (RCW 46.61.415 § 1-C)

I can think of a pair of white-on-black 1960s speed limit 15 signs in California.  I can't think of a 10 offhand but I'm pretty sure I've seen it.

if you stretch the definition of "public", then certain truck weigh stations in CA have speed limit 3, and advisory speeds of 1 and 2.

That extends into Washington as well.

You are correct sir.  The Hairpin Turn on MA 2 does have a regulatory speed limit of 15 mph.

Massachusetts posts regulatory speeds in advance of curves instead of advisory speeds. I treat all of them as advisory.

MassDOT, perhaps.  On the Route 16 westbound curve just before crossing 93, the dcr has two standalone 35mph yellow (advisory) signs of the kind designed to append to the bottom of a yellow diamond.  State Police run radar at the Main St. exit gore just beyond here — I'm very curious to know if they attempt to enforce that 35, or the actual 45mph statutory limit for this segment.*

* Not curious enough to find out, though.

I would think they are enforcing the 45 mph limit.  Why that 35 mph sign is even there without a reason why isn't proper signing.

Then again, just up the road, this sign is just bullshit...

[Pete from Boston]

Both those links are the same, but I will say the dcr seems to run its signing operation with a "how hard could it be?" approach.  There are so many sign anomalies and inconsistencies on their roads that I usually don't even post them here because it's an old, tired story that goes nowhere fast.

IIRC, several years ago one motorist (not me) got pulled over for speeding in an area where the only signs were advisory panels; this occurred in central Massachusetts.  The motorist just happened to be a road sign contractor and noticed that the sign in question was indeed an advisory panel and not a bonifide regulatroy speed limit sign.  he challenged his ticket on those grounds and won.

Shortly after that ticket was thrown out, just about every solo speed advisory panel (including the ones on the Mass Pike then-Fast-lane booths) were replaced with the standard regulatory speed limit sign.

I guess DCR and/or that particular MassDOT district didn't get the memo regarding the above-incident.

They alleys in my neighborhood have 10 MPM speed limits. To go any faster would be unsafe. They alleys can even be unsafe at 10 because people cannot see far enough to back out safely because the fences are too close.

The alleys in Brigantine are pretty generous by the standards I've seen here. They're all rated for 15mph, but two full-fledged streets (Lincoln Drive and Vardon Road) have 15mph limits as opposed to 25mph for the majority of the island (and in the case of the latter it might – and should – extend to Duncan, Ray, and Quimet). Lincoln Drive is narrow and one-way, and Vardon was docked due to resident complaints.

I believe some streets in Upper Darby Township are rated at 15mph as well.

There is also one parking garage in Atlantic City rated at 9mph, and a road in a housing development in Hamilton Township rated at 23mph for the express purpose of it getting motorists' attention.
