I do not know if anyone posted this before or not, but the State of Florida used to have statewide interstate and freeway minimum speeds that if a vehicle was going slower than that, could be ticketed unless there is heavy volume of course.
Sometime in the 90s the Florida Turnpike Enterprise and FDOT District 5 removed the signs in their jursidictions, but other areas in the state kept them still. It was 40 mph when it was all over, then it beacme 45 along I-4 and now, I believe it became 50 in Polk County on I-4.
What other states still practice this kind of thing? I know that PA uses it on its Turnpike, but I am not sure if its regular interstates practice it there.
New Mexico has a minimum speed of 65 for the left lane of I-40 (maximum speed 75) west of Albuquerque.
Quebec usually posts a minimum of 60 on autoroutes where the maximum is 100.

That is a good one. It makes sense as I know many drivers who drive slow in the left lane around my area. Even my friend from Fort Myers, FL loves to ride the left lane all the time. Even if he has the road to himself, he stays in the fast lane.
I only ride the left lane on streets where I know I will be making a turn soon, or on OBT in Orlando I use the middle lane to avoid the local buses that stop in the far right lane along with the many right turns people make along this highway.
Many states have them.

I was on I-10 in far western Florida within the past couple of weeks, and wondered at first why there was a large blank space under the speed limit. Then I observed the bottom part had been covered and I concluded a minimum speed had been removed.
On a routine basis along interstates, I've not seen a minimum of over 40, except in areas where left lane laggards are a problem (edge of metro areas such as Denver). Key word here is "routine", such as the way Minnesota posts its interstates statewide. The road I commute to work on every day has a 55 mph minimum even though it's an expressway with signals.

But not all.
Wisconsin, for example, has no minimum speed. Iowa has 40 mph, Illinois and Indiana have 45 mph, and Michigan uses 55 mph in their 70 mph zones.
South Carolina posts a 45 minimum on nearly every interstate except the last mile or so of I-26 in Charleston, which has a maximum of 50 and a minimum of 30.
Georgia pretty much posts a minimum of 40 all over the state, and puts it on a separate sign from the regular speed limit sign.
Tennessee posts a minimum of 45 only in urban areas, but I believe 45 is implied statewide.
Louisiana posts a minimum speed limit on I-10 in Baton Rouge of 45 MPH, and a maximum on the Basin Bridge of 60 MPH for passenger vehicles, and 55 MPH for cargo trucks.

Nope, Illinois still has it. It's just not always posted in Cook County, and only Cook County for some reason.
OK has 40.
Question I've had before: is the minimum absolute? You can theoretically be ticketed for driving too fast for conditions, even if that is under the statutory maximum speed limit. Of course this is not a problem because the speed limit is an upper bound and it is okay to drive below it. But can the lower bound be disregarded if conditions require it? Am I obliged to maintain a speed of 40 mph in a snowstorm? (Of course, no cop is going to be out in the snow enforcing the minimum speed limit, as they're needed to respond to wrecks and help dig people out of the snow, but the lawyer in me wants to know...)
Maryland has generally not posted minimums on its "free" network, but I have seen minimum limits on the MdTA (tolled) system in some places in the past (though not recently), usually 40 MPH (which is pretty fast for a road like I-895, where the posted maximum is 50 MPH for long segments).
I have never seen a minimum posted anywhere in Virginia. State law prohibits driving, quote, "at such a slow speed as to impede the normal and reasonable movement of traffic except when reduced speed is necessary for safe operation or in compliance with law." The statute allows for the posting of numeric minimums, but I don't believe it's ever been done.
I can think of at least one situation where I was doing 20 mph on I-85 late at night somewhere near McKenney in a torrential rainstorm with my hazard flashers on and it still felt like I was going a bit fast. (I know it was somewhere near McKenney because I knew someone who lived there and I was seriously considering stopping there to get out of the rain.)

I haven't bothered to look up chapter and verse in any state's statutes, but I believe the answer is No--a posted minimum speed limit cannot override your responsibility to go no faster than the conditions will permit. In fact, you can be ticketed for excessive speed while travelling at less than the minimum speed limit if the police officer judges that you are going too fast for conditions (e.g., in the middle of an ice storm that deposits glare ice on the road surface).
I have never known Kansas to post a minimum speed limit other than 40 MPH. Colorado also uses lane-by-lane speed limits on westbound I-70 up Lookout Mountain just west of Denver, but I am not aware of any Interstate minimum speed limits elsewhere in Colorado. (With the exception of the lengths of I-25 in Denver and Colorado Springs that were upgraded through T-REX and COSMIX respectively, urban Interstates in Colorado are badly aligned with numerous mainline curves requiring advisory speeds and so are unsuited for minimum speed limits which create an obligation for drivers to maintain their speeds within a narrow band.)

VA hasn't had a "minimum" speed limit since at least the late 1960's and probably not even before then. Of those states that have them, some add "when conditions permit" to their minimum speed limit sign - I know that UT does this.

I would think that in some instances, driving very slowly on a freeway might be grounds for getting one of those (in)famous Virginia reckless driving summonses.
§ 46.2-852 of the
Code of Virginia reads (I just copied this off of the LIS, so I think it is current):
QuoteIrrespective of the maximum speeds permitted by law, any person who drives a vehicle on any highway recklessly or at a speed or in a manner so as to endanger the life, limb, or property of any person shall be guilty of reckless driving.
It does say
maximum above, but I would think that driving at 20 MPH when the pavement is dry and the road is not congested might well qualify as an act that could "endanger the life, limb, or property of any person."

That would presumably not be considered reckless driving. Heck, driving at or close to the posted limit under those conditions would easily meet the definition of reckless driving!
The only one I've seen in NY is the 40mph minimum on I-787, though the Thruway has a "flashers on under 40mph" law. Vermont has a 40 minimum on rural interstates; NH is either 40 or 45. I don't remember if Maine does this or not.
I've seen a minimum speed posted in Virginia - on the US 17/258 James River Bridge. If I recall correctly it is 35.

On the freeways in New Hampshire with a 65 speed limit, there is a minimum 45 speed (http://farm9.staticflickr.com/8430/7630822658_d4880b2fd4_c.jpg). Maine also has a minimum 45 I believe, but it's only on the Maine Turnpike from what I've seen.
I know on I-84 in Utah north of Ogden, the minimum speed limit has a "when conditions permit" banner below it.

Some would say the
de facto speed limit in Michigan increases as one gets closer to Detroit from 80 to 100 mph. The MSP have been known to pull over drivers that go too slow on the freeway or obstruct traffic (i.e. left lane hogs), even if the driver is going the posted speed limit.

Texas has been known to enforce "traffic flow" over speed. I was pulled over once near Dallas for doing the posted limit in the right lane, but since EVERY vehicle had to pass me, the cop decided I was impeding the free flow of traffic. I went to court of course, ticket was dismissed instantly.

NJ generally doesn't have a specific minimum limit. And probably due to that, there's no signed minimum throughout the state.
NJ's Laws:
27:25A-21. Traffic regulations; violations, penalties:
Subsection (d): No person shall operate a vehicle on any project at a slow speed as to impede or block the normal and reasonable movement of traffic except when reduced speed is necessary for safe operation thereof.
Subsection (g): Regulations adopted by the authority pursuant to the provisions of this section shall insofar as practicable, having due regard to the features of the project and the characteristics of traffic thereon and except as to maximum or minimum speed limits, be consistent with the provisions of Title 39 of the Revised Statutes applicable to similar subjects.
39:4-97.1. Slow speeds as blocking traffic
No person shall drive a motor vehicle at such a slow speed as to impede or block the normal and reasonable movement of traffic except when reduced speed is necessary for safe operation or in compliance with law.
Having said that...the NJ Turnpike Authority does have a 35 mph minimum...
http://www.state.nj.us/turnpike/documents/regulationsunofficialversionforWebsite.pdf (gotta like that website address...notice the "Regulations unofficial for website"??!!)
(j) No vehicle shall be operated anywhere on the Roadway at such a slow speed as to impede or block the normal and reasonable movement of traffic, or in any event at a speed of less than 35 miles per hour on level ground except where otherwise posted or when specific hazards exist with respect to traffic, road or weather conditions.
Pennsylvania has always had a minimum speed on expressways of 40 MPH. But is seldom posted.

Don't forget that Montana does not practice minimum speeds. I-15, 90, and 94 are 75 MPH, 65 for large trucks. US highways 2, 12, 20, 87, 89, 93, 191, 287, and 310 are between 55 to 70 MPH, trucks at between 55 to 60, nighttime limit set to between 50 to 60. Montana state highways are around 55 to 70, and secondaries are somewhere between 45 to 60.

Not completely true. There may not be a
numerical, statutory minimum speed, some urban Wisconsin areas do have posted minimum speeds. I've seen a few of the highways around the Milwaukee Metro posted with a 45 minimum. And while not used very often, WisDOT does have a standard minimum speed sign plate.
Quote from: §346.59 Minimum speed regulation.
(1) No person shall drive a motor vehicle at a speed so slow as to impede the normal and reasonable movement of traffic except when reduced speed is necessary for safe operation or is necessary to comply with the law.
(2) The operator of a vehicle moving at a speed so slow as to impede the normal and reasonable movement of traffic shall, if practicable, yield the roadway to an overtaking vehicle whenever the operator of the overtaking vehicle gives audible warning with a warning device and shall move at a reasonably increased speed or yield the roadway to overtaking vehicles when directed to do so by a traffic officer.
Cleveland has some examples of combo signs that go as low as 50/35 on I-77 (http://goo.gl/maps/vau1v); Akron has some bizzaro unattended "Minimum 40" signs (http://goo.gl/maps/jf1sJ) nowhere near speed LIMIT signs. Outside urban areas I don't recall seeing minimum signs in Ohio, although there may some I haven't seen.
While technically, Washington does state that a minimum speed limit can be designated by local traffic engineers and/or authorities (http://apps.leg.wa.gov/RCW/default.aspx?cite=46.61.425), I have yet to see a posted minimum speed limit sign. I have never seen one in Oregon or California as well. I believe that impeding traffic is a traffic violation that practically all states share.

black with white text on a speed limit sign is - theoretically, anyway - regulatory. at least, in California, prior to 1971.
as for minimum posted speed limit - yes, every state has one, by definition. I'm willing to bet most general-use ones are 5mph. some states will have weigh stations that go lower.

The State of New Jersey's definition isn't a numeric number. It's simply driving as such a slow speed where one is blocking traffic.

All the interstates in FL used to have minimum 40. A few years ago where the speed-limit is 70 the minmum is now 50. I saw an article I think on Jacksonville.com that said it was changed because they wanted the set minimum speed no more than 20MPH below the posted maximum

What I think he means is the grammatical difference between "minimum posted speed limit" and "posted minimum speed limit." The former simply means the lowest number on any speed limit sign anywhere in the state. The latter means they post a sign advising of the lowest legal speed

Then the permanent speed limit for the zone is 60. The 30 is the same as if there was a work zone or something. It's temporary and specific to unusual circumstances.
In Alanland, the minimum speed limit is higher than the maximum.

When the speed limit on the interstates went up from 55 to 65, Arkansas implemented a stacked sign that had 65 on top, and Minimum Speed 45 on the bottom.
Now that the SL has been raised to 70, the bottom sign reads Trucks 65.
I believe it was Colorado I was driving in recently that posts a minimum speed for the left lane (Minimum Speed 55). If anything...I think it caused confusion! I noticed a few times cars would slow down apporaching the sign, thinking the speed limit was going down.
This is not a state standard, but I thought Mexican minimum speed limit signs were rare enough to be of interest on this thread:

now
that is a challenge to differentiate from a maximum sign offhand. if I weren't carefully reading the words, my first instinct would be to think "120 cars, 80 trucks".
I wonder how well that is enforced. I've seen donkey carts on Mexico freeways before! :pan:

Usually not toll roads, though, to be fair...
I'm guessing there's less of a difference between freeways and surface streets in Mexico than the US and Canada given that maps don't differentiate.

What maps don't differentiate? My atlas differentiates between divided highways, "supercarreteras", and regular old two-lane roads. Tolled segments are marked with a "D" shield, and free ones are not. An example of the cartography is here (http://store.milwaukeemap.com/milmapstore/content/images/thumbs/0002423_guia-roji-mexico-tourist-road-atlas.jpeg). Maybe you need different maps (http://www.guiaroji.com.mx/).
But anyway, non-motorized traffic is much less common on toll roads. Many of them even prohibit cyclists from using them. Having personally driven part of the toll road that that sign is posted on, I would be
very surprised to encounter non-motorized traffic on it. However, I would be
less surprised to encounter a vehicle travelling at less than the posted minimum. Those speeds, in fact, are as high as those on Oklahoma's turnpikes–which have surprisingly high minimums. 80 km/h equates to 50 mph; there are a great many trucks in México that struggle to maintain that speed. And, as the highway goes on toward the west, it encounters uphill grades steep enough to thwart even early-model, poorly maintained passenger vehicles. Shoot, on some mountain roads in the area, even
I struggle to maintain 80 km/h at all times.
I can't think of any of the major online maps that get it right, though OSM comes VERY close (the issue here probably arising from the fact that not all freeways in Mexico have full access control, such as route 1 in Tijuana along the US border).
Well, not differentiating and not getting it right are two different things. I challenge you to find any mapping program that gets everything right.

black with white text on a speed limit sign is - theoretically, anyway - regulatory. at least, in California, prior to 1971.
as for minimum posted speed limit - yes, every state has one
0 MPH :P

But it's only 40 on non-tolled freeways.

posted?
even if you are backing up, your speed is greater than 0mph. your velocity is negative, but we don't have velocity limits in this country, otherwise every yahoo with a physics degree would install a transmission backwards and do 95mph looking over his shoulder.

But, they're still lower than the highest posted minimum speeds in North America. Those belong to Michigan, where the minimum speed must be 55 mph (88 km/h) on the freeways where the speed limit is posted for 70 mph.

New Mexico has a minimum speed of 65 for the left lane of I-40 (maximum speed 75) west of Albuquerque.
Pennsylvania has a minimum 40, but does not post it for some reason. You can't enforce it if you don't post it.

Sure you can. One can be stopped on the many roads that has a statutory 55 mph limit without it being posted as well.
Crossed the Potomac River recently on U.S. 301 (Gov. Harry Nice Memorial Bridge (http://en.wikipedia.org/wiki/Governor_Harry_W._Nice_Memorial_Bridge)) and noticed the posted limit was 50 MPH (which it has been for a while), and a minimum speed of 40 MPH (which I had not noticed the last time I crossed there).
This may be the only segment highway in Maryland that currently has a minimum speed limit posted.

I want to say that I-895 SB has a minimum speed upon leaving I-95, but it may be work zone signing that I'm misremembering.

I remember when I was a kid the Harbor Tunnel Thruway (it wasn't I-895 at the time) had a posted minimum of 40 mph.
I noted last Saturday that the speed limit on I-695 in DC has been raised from 40 mph to 45 mph from I-395 to the work zone for the 11th Street Bridge project. Compliance with the higher speed limit was every bit as good as it was with the old limit.

New thread idea: States where drivers obey work zone speed limits. I'm drawing a blank... (There are a handful of states, in the South for example, that don't reduce speeds automatically. That'd be the best place to look.)
I know I-90 in South Dakota has a minimum speed limit of 45 mph posted entering the state from Minnesota, but I haven't seen it posted anywhere else on the entire highway.

In Illinois, they're readily ignored by most folks. Of course, this might be because Illinois insists on having a 24/7 45 mph work zone speed limit whether workers are present or absent.

As Hoo mentioned above, I-895 (in the pre-I-895 days, and perhaps (IIRC) after the shields went up) had a posted minimum speed limit, in particular on the northbound side after exiting the tunnel. Like the Nice Bridge now, I think the posted limit was 50 MPH and the minimum was 40 MPH.
I do not recall having seen a minimum posted limit on Maryland's I-895 recently.
As an aside, the MdTA has (
somewhat recently) raised the posted speed limit on I-895 between I-95 and Md. 295 from 55 MPH to 65 MPH.

Maryland has work zone speed limits on freeways that are sometimes the same limit as the "normal" posted limit, but with camera enforcement (the enforcement vehicle is always a white Jeep SUV). There's such a 65 MPH work zone limit on I-95 through the Md. 200/Contee Road/Md. 198 construction area right now.
A few years ago, there was a 55 MPH work zone (photo-enforced) on I-270 south of Urbana in Frederick County, where the normal posted speed limit has been 65 for quite a few years. There were some pretty significant lane shifts for the redecking of the bridge that carries 270 over Bennett Creek. The work zones were in place when GSV imaged that section of the highway (here (https://maps.google.com/maps?q=i-270+urbana+md&hl=en&ll=39.307688,-77.34463&spn=0.009281,0.01929&hnear=Interstate+270,+Urbana,+Frederick,+Maryland&t=h&z=16&layer=c&cbll=39.308043,-77.34515&panoid=CzogMM9ylufvCmHL669PJA&cbp=12,313.95,,0,14.42), but the project is now complete).
To answer your question, the presence of photo enforcement does seem to get drivers to obey the posted limit.

I find it very curious that D.C. has automated speed limit all over the streets and highways under its direct control, yet
not once have I see any hint of automated enforcement in this work zone since construction got going several years ago.
In New Hampshire, there is a sometimes a minimum of 45 and a maximum of 55. That is a close range.
