What is the longest stretch of road where you can go "straight" through every intersection? In other words, how long can you drive without using your blinker to turn?
A few rules:
- Freeways are allowed
- Changing lanes is allowed
- Merging is allowed
- You may not exit a road if it involves the use of your blinker
Here's a few examples:
Stretch involving US-2 in Upper Michigan (https://goo.gl/maps/8pTz8QrfeS5SF8ms7): 197 miles
Stretch involving US-2 in Montana (https://goo.gl/maps/d2YiQ2CdmjdBinNk8): 411 miles
There are probably some dead ends in northern Canada that are 300 miles long or more. As these are just two-lane rural roads the whole way, blinker use is not needed.

A few rules:

- You may use your blinker when changing lanes
- You may use your blinker when merging onto a freeway
- You may Not exit a road/freeway if it involves the use of your blinker
- Roundabouts require the use of blinkers and are not allowed

I-75 from Sault Ste Marie to I-375 in Detroit is over 340 miles. While some people
might use their turn signal at the US-127 split, it's not
required as it is 127 that is exiting.
Edit: And if you were going northbound, that wouldn't apply.
Going south from Detroit, I'm not sure if there's any reason to use a blinker at least all the way to Lexington, and maybe not until Knoxville.

Knoxville. I-75 southbound merges onto I-64 eastbound. Both interstates are two lanes, so the route becomes four lanes until the KY 922 exit. At the southern split, I-64 requires a left exit.
Once you get to Knoxville, I-75 narrows to one lane to merge onto I-640, and it's an exit situation (the through route becomes I-275.)

I would argue that you can continue on I-75 through the I-75/I-375 interchange without changing lanes (for both northbound and southbound). For going northbound, two of the four continuous lanes fork off for I-75 north. For going southbound, there are two lanes forking off for I-75 south: the left lane would not require changing lanes, while the right lane would require the use of a blinker.

It would, however, be impossible to be in that second-from-the-right lane of I-75 SB without having changed lanes, because it it's an added lane from the I-94 interchange (MP 53).

Agreed. However, the addition of that lane is far enough upstream to where I would consider it part of the mainstream (instead of an exit lane).

What I meant is that you can't continue through on I-75 without using a blinker, if you've come from any farther north than I-94. Doing so requires a lane change.

Yes, totally agree with you. That being said, would you say that I-75 is not continuous through that I-75/I-375 interchange?

Perhaps these situations should be prohibited in the guidelines.

A lot of beltways might not work as well as it appears at first glance, due to changes in alignment at major junctions and a varying number of through lanes in general.
You can get from the Pacific Ocean at Seattle to at least Tomah, WI on I-90. And you wouldn't really need to use your blinker when merging onto I-94 at Tomah, so in that case you could get to Chicago.

You could theoretically drive from JFK to the exit for Logan. Leaving JFK, head north on I-678, which turns into the Hutch, which becomes CT 15 (Merritt and Wilbur Cross Parkways). Proceed up the Berlin Turnpike, then onto the South Hartford Expressway (it's a slight bear right but it's the through route at the split) over the Charter Oak Bridge onto I-84. At the east end of I-84, most lanes default onto eastbound I-90 (Mass Pike). Follow the Pike to Logan.

You do have a point - that's why I said "a typical" and not "any" in my post :) Also, recall that the OP did allow lane changes.
That said, the beltways I'm most familiar with are Baltimore's and Washington's. I-695 is probably disqualified with the goofy alignment in the southeast quadrant near the Windlass Freeway. I-495 could have issues with its merges with I-270, but that would be up to interpretation I think.
I've also clinched the beltways around Charlotte, Atlanta, and Jacksonville, but not enough times to know if they satisfy the criteria.

I don't think that I-5 has any lane weirdness for passenger cars from Downtown LA to Seattle. As far as I know, I-80 has no weirdness from West Sacramento to Cheyenne and probably to Omaha. You might have to change lanes and merge or keep right in some cases (as permitted in the rules of the OP). You might even have to stop for agricultural inspection. Trucks may have to take the truck bypasses.

This means if I hit a roundabout I have to end there, since I'd have to use the blinker in order to exit. Thus, a run starting on the Santiago bridge in Zaragoza, Spain would end at a roundabout just South of Sabiñanigo, while just 10 years ago it would have gone into la France. However once both A-21 and A-23 are completed (Only God knows when) one will be able to go as far as the Boulevard Periphérique around Paris :sombrero:.

All three of those beltways would satisfy, aside from a couple left exits, they're continuous.

I was trying to come up with a goofy routing starting in Tulsa on the Creek Turnpike, then following I-44 to Downtown STL and transitioning from I-44 east to I-70 west and ending at I-70's western termination to see if it would qualify. My biggest ?s would be where I-70 leaves the Kansas Turnpike and also I-70 in Downtown KC (both MO and KS).

If changing lanes is allowed, the Capital Beltway would work. If changing lanes isn't permitted, you'd run into a problem on the Outer Loop approaching Springfield (this because when you pass the I-270 Spur, you land in the far right lanes, but then at Springfield the right HO/T lane and the leftmost two general-purpose lanes continue thru on the Beltway, while the rightmost three general-purpose lanes all exit to I-95 and I-395) and on the Inner Loop approaching the I-270 Spur (this because at Springfield the thru lanes on the Beltway become the HO/T lanes and the left two general-purpose lanes, and then at the I-270 Spur the three left lanes go to the Spur and the three right lanes stay on the Beltway).

If TOTSOs could be defined as situations where legally a blinker would be required, then there's a singular continuous route from the East Los Angeles (I-5, I-10, CA 60, US 101) interchange via NB I-5 to NB CA 99, NB CA 99 to NB CA 51 (Biz 80 be damned!), NB CA 51 to EB I-80, and then EB I-80 to I-15 in SLC, UT. But
that routing terminates at another long straight stretch: all of NB CA/I-15 from I-5 in San Diego onto WB I-84 in UT, with that route terminating at the I-86 merge (a blinker would be required to get on to the WB carriageway coming off I-86).

If those same TOTSO rules applied here, that would disqualify the I-90 TOTSO east of Billings, MT; the through route would segue onto I-94 -- and then onto I-694 coming into the Twin Cities, at which point the straight line would segue onto SB I-35E and then back onto EB I-94 in downtown St. Paul. From there it's simple: I-94 to I-90, I-90 into Chicago and, again, I-94 onto IL 394. I'd consider the terminus the south end of the 394 freeway/expressway at the IL 1 merge.
