While looking at Google Streetview of the Trans-Canada highway near Regina, SK, I noticed that two head signals are being used for left turn lanes. The top is a red LED ball, the bottom is a combination yellow/green LED arrow.

Why use this as opposed to a convention r-y-g three head arrangement?

Other signals along the route have left turn signals with R-R-shared yellow/green.

Never seen that... do you have a link on street view?

If that doesn't work, look for the address of Prince of Wales Drive / Saskatchewan 1, Regina, Saskatchewan, Canada.

It is on the east side of the city along the Trans Canada Highway.

I remember when I lived in Southern Alberta when my dad had a visiting professorship up there, about 20 years ago, Calgary was starting to get into bimodal arrows. They always used 2 red lights on their LT signals so you started to see 3 sections with 2 reds and a bimodal on the bottom. Alberta always flashed the green arrow, so the bimodal didnot pose a color blind problem. Not as bizzare as that 2 section though

More proof that standardized traffic signals STILL don't exist. Technology moves us forward and confuses the old timers.
