No turning left on this left turn only lane.

I'm pretty sure it's saying you can't turn left onto the road to the left of the intersection. Looks like some pretty bad road design.

I didn't realize we were here to play geoguessr but you win!
- I'm gonna say it's easy when the street names are in the photo.
- Mr 305 ova'ere
I understand the intent from your graphic, but given the signage, I would not have known what they expected of me.
- The painting on the road should indicate a 45° left instead of 90° left.
You're absolutely correct. I just thought it made for a funny photo. It's very on brand for this city to do dumb shit like this.
- I've been confused and made dangerous choices in traffic for less stupid reasons. Not trying to deflect all blame but considering the lowest common denominator, road construction and signs really need to pay much more attention to the limits of the human brain.
  
  Half of us have an IQ below 100 and we could be driving in darkness, with rain pouring down and facing traffic that shines its headlights into our eyes. The road needs to have an affordance that suggests to the driver how to drive correctly, instead of causing confusion when you already have a lot of traffic to keep track of.
Bad road design for sure, but the sign still could be better. For example they could make a custom sign, draw the intersection and mark explicitly that you can't turn to Oakwood.
- Or just have the sign arrow be more than 90°
This is exactly the type of content i was hoping for when i clicked on the comments. Thank you for all you hard work sluthing for an explination of a random photo. Its truly gods work that your doing.

Apart from what some commenters already pointed out (about the orientation of the roads there), I'm not sure how it's going in the US, but in Europe, we have a hierarchy, where the sign on a pole takes precedence over the sign painted on the road.

The hierarchy is:

Police officer's hand signs
Traffic lights
Signs on a pole
Signs painted on the road

According to this, you cannot turn left, even though it looks like a left turning lane.

Is there such a thing in the US?

Is there such a thing in the US?

Yeah.

Whatever the heck I want, because "ma freedom"

Police officer's hand signs

Traffic lights

Signs on a pole

Signs painted on the road
in Europe, we have a hierarchy

This is definitely not true for all of Europe. In Germany, for instance, signs on roads have equal precedence to signs on poles.
- What do you do if they contradict?
Lately the trend is for temporary signs to have yellow background instead of white. So if you see road construction you'll see a yellow background sign.
- Orange you sure that construction signs shouldn't be a different color?
- Oh, I was always told the yellow signs are suggestions

Florida. No other explanation needed.

For real. It's not even the dumbest shit I've seen today. Someone missed an entrance onto i95, so they drove up the offramp intended for the opposite direction. Got 50ft before an oncoming car made them realize their mistake.
- I overheard someone in a court house trying to argue with who I assumed was their assigned counsel that it's totally legal to enter on an off ramp, as long as you're going in reverse.
Gators?
- Gators could design better roads. Don’t insult the gators.

Sometimes construction makes for unexpected detours.

(I should probably mention that it's also a dead end road, so no backing out)

They really said "fuck that house in particular!"
Gotta jump that roof like a ramp
- The guy that owns that white car already fell into this trap and got stuck, said screw it, parked, and just moved into the house.
that's the sign for "make a new friend in a yellow house with red shingles"

It’s a detour…you have to drive through the bush.

Hi neighbor .... we should really make /c/miami

I'm surprised it doesn't already exist. Do you want the honors? I already mod a few groups here, I can easily help with that too.
- Do eet! I don't have the time to run ANOTHER community
I knew it. I said "I've only seen road design this bad in one so-called state."
- Miami dade exists in it's own state separate from Florida ....
  
  a state of chaos (and it's constant)
I'll join
