Title: Split Phase Intersections without protected left arrows

NJ seems to have split phases over normal protected lefts  or even permissive signals for left turns. Many places use a fixed fourth section arrow on the left side signal head, a left side 3 section with arrows instead of balls, or a doghouse head with the green left arrow mirroring it's straight through counterpart, but in my home state you'll occasionally get a normal red- yellow- green head and have to know that your green light offers full protection from on coming traffic.

Is this limited to only places in NJ, or are there other places where an intersection wrongly signalized exists?

Notice: Pan the above image around to see the green light facing opposite the red and look at both cars crossing the stop bar.

yawn you are looking at old signals

Looks like no other state. If only the one response here is a troll not pertaining to the discussion and no discussions from others. It seems like it's a flaw of New Jersey to program a signal different from 49 other states.

There's an NYSDOT signal near me, on US 9 in Fishkill, where there is a split phase for the side road. There's no arrow if you're on the side street, just a RYG ball. It was changed a few years ago, you used to have to yield. They put up a Left Turn Yield on Green at the Poughkeepsie Galleria a few miles north because people got too comfortable assuming they were protected

There are some old ones kicking around Massachusetts.

An example of one in Wilmington, which is at this moment being replaced with hopefully something better. Annoyingly, the westbound side is what has the split phase ahead of the eastbound side, despite the eastbound side of 129 having its own left turn lane.

This signal on NY 386 (Elmgrove Rd.) is split phased for some reason.

The entrances for Rochester Tech Park and Total Sports Experience each have their own phases. Signals have no arrows.

Is it really a troll response? If new signals in that state are compliant, then you can't use the older signals as an example of non-compliance

69th St and Queens Blvd in Queens, NYC

Unsigned southbound, northbound only has a WAIT FOR GREEN LIGHT sign as a clue.

Further down, Grand Ave/Broadway at Queens Blvd was recently converted to split phasing. Uses FYA to emphasize yielding to peds (lots of peds during the day), but no obvious indication of split phasing. FYA is only linked to the same-direction green and not the opposite direction green. Better than nothing
