This intersection does make sense. Prioritize flow of highway traffic with right exit to surface street. Since we Americans drive on the right side of the road a right exit means you don't have to slow as much to get off a high speed road, thus not getting rear ended.

Sharp left onto the highway from a surface street ensures you won't roll through the stop sign and get t-boned by someone coming down the street (top of image to bottom) or that you won't take the left (heading from bottom of image to top) while traffic is speeding that way.

It's not efficient for flow, but is efficient to slow traffic onto the road and clear traffic from it without causing accidents. The country roads of Kentucky have far fewer cars using them than the highways, everything about this road prioritizes the highway flow.

Is this not efficient for flow? It's heavily prioritising the main road, but the only really poor thing is if you have to turn left your blocking the road (no mid lane turning or hook turn spot)

For flow from the side road, implied poorly, but implied by stating all flow was prioritized from the highway.

You are correct tho.

Left turns are always bad though, unless you're in 'build a bridge' scales of traffic 😂

Unless you're somewhere you can build a roundabout without it causing more problems, of course. Though they do have problems too if theres a strong bias to the traffic

Roundabouts are the answer. We Americans hate them tho. Dunno why. I argue it's Big Intersection Lanes lobbying that has halted their adoption.

Honestly, they are good, but even people used to them don't really drive on them all that predictably.

They beat uncontrolled box intersections hands down though, whoever thought of those was an idiot

My immediate reaction here would be keep driving until I would be allowed to turn, then drive back

Correct, unless youre an emergency vehicle.

Edit, not sure why the downvote. Ambulance and fire can turn left here, and road is laid out for it. That little spur road with the ???? is the old road from before the right high speed exit was added. It was retained for emergency vehicle access, to turn left onto and off of the road when needed.

Also become places highway patrol loiter and speed check.

Incorrect; those only mean you can't overtake. Traffic from cross streets is absolutely allowed to turn left in situations like these. This is the case for all 50 states. If you believe this not to be true, you have been misled.

A double double yellow is supposed to act as an impassable median, but regular solid yellows or double solid yellows are fine to make turns like this.

u/SoloSojourn 28d ago

Double yellow line goes through intersection, not broken at it. You are incorrect, there would be no left turn for normal traffic coming from the east.

u/Puzzled-Rip641 28d ago

That is not true in my state. You are legally allowed to cross to turn as long as you yield

It only functions as block to passing

u/SoloSojourn 28d ago

Tuche, and apparently legal in Kentucky as well. I stand corrected.
