Speed Limits in the United States and Canada

So I've decided to create a thread dedicated to speed limits (both past and present) in the United States and Canada.

The current top speed in the US is on a toll road in Texas:



A far cry from early 1974 when the US adopted a federally mandated speed limit of 55 mph in response to the oil embargo:

Map of maximum speed limit in the USA

They don't have speed limits in Nunavut? Granted, there aren't (m)any paved roads outside towns.

Are those limits respected? 65 mph is an awfully slow speed to drive America's long distances...

On 95 in Pennsylvania, which for some reason has a 55 limit its entire way through the state, I generally do about 70 and keep an eye out for cops. My father used to recommend "keeping up with traffic" - if everyone's 15 miles over the limit, they're not going to stop and ticket everyone.... (Speed cameras are still rare here, and may be nonexistent on freeways.)

Also, maybe I'm not getting into rural Pennsylvania enough lately, but I was surprised to see Pennsylvania labeled on that map as 70. Either that's a recent change or it's a mistake; I thought the nearest 70-mile zones to me were in Virginia and West Virginia.

It is a recent change and only in a few places, places I haven't been since:

The speed limit on sections of the Pennsylvania turnpike, I-80 and I-380 was raised to 70 mph in July 2014.

They rarely are; it's common to drive 10 - 20 mph over speed limit. Obviously when people see a police on the roads they slow down

65 mph = 105 km/h

Ontario's and Quebec's maximum speed limit is 100 km/h!!!

What's going on in Southeast Texas? Looks as if Harris County (Houston) has a higher limit than most of the surrounding ones....

PEI is 90, but it doesn't have a freeway on it, so that makes sense.

Ontario has a 100km/h limit but it is in effect 120. There aren't any speed cameras in the province so the speed limits only matter for cops who rarely ticket for less than 20km/h over, unless you are doing 70km/h through a town that is zoned for 50km/h or something. (you should always obey the speed limit when there are pedestrians around anyway if you ask me)

Ontario has among the best highways in the world; 100 km/h is a shame (even if people speed). That speed limit should be in urban areas, but not when you leave the urban areas.

110 km/h makes more sense.

Ontario and Québec should allow at least 120 km/h on freeways outside cities. Even in the prairies you can go faster on non-freeways.

There is a lot of money to be made on the Hwy 401 fishing hole... at 120 km/h you'll fall asleep. So you try and drive 140 like much other traffic, but watch for cops. In Eastern Ontario they had Mercedes-Benz patrol cars for a while, and Volvo S70 T5's, and now, unmarked black Toyota Venzas. There are few people there, probably police outnumber residents, but many Toronto and Montreal people get a haircut on their wallet...

Anyway it is important to note the "Maximum 100" limits in Ontario and Quebec date back to a similar thing as the 55 mph in the US. Specifically the federal Trudeau government circa 1974 pushed for a maximum speed limit of 60 mph. Quebec, Ontario, Alberta and other places typically had 70 mph speed limits on freeways and 60 mph speeds on 2-lane roads. Ontario put freeways at 60 and 2-lanes at 50, Quebec put freeways at 60 and 2-lanes at 55. After metrication it became 100/80 in ON and 100/90 in PQ.

I believe BC had the same thing but eventually relented and allowed 110 again, and now 120. Alberta I think consistently ignored the deal (annoying Trudeau was a bonus) and kept 70/60 until today's 110/100 AFAIK.

Not even, look at Ontario's urban freeways, they do not require reduced speeds at all. 140 is a decent limit on pretty much all the GTA-region freeways aside from junk like the Gardiner... if anything traffic is moving much faster on uncongested roads in the GTA than elsewhere in Ontario (probably because the drivers are familiar with the roads and/or where the cops hide!)

Look at the A4 through Katowice, Poland, it has a collector-express setup like the 401... IIRC 2+3+3+2... The express lanes are limit 140 and the collectors limit 120. It works well - and this road is like half the width or standard of newer parts of 401 across the GTA... where people are driving 140 right now all the time so clearly safety is not an issue.

I-5 in Seattle is nominally at 60 mph (100 km/h), but it has variable speed limits northbound if traffic is bad, which is most of the time.

Good luck even getting to 35 in that situation.

Lane-discipline fetishists will note that treating every lane but the far right as a passing lane is actually illegal in that situation....

I've seen trucks attempt to go into the left HOV lane from time to time. During the afternoon it gets better once you pass downtown and can get into the reversible express lanes. You could possibly get to 60 there.

Is the 50 a HOV lane? That wasn't clear. I thought they were encouraging passing in the left lane by permitting a higher speed.

It reminded me of something someone once posted - from Buenos Aires, I think - of a freeway with a good number of lanes where each lane had a different speed limit, each one 10 km/h higher than the next one to the right.
