Photo radar?

[Dezmo]

Hope this is applicable to this group...and I should have asked before... 

Rented a car last week at Chiang Mai (CNX) and  drove south and SW.... and thanks for the tips here.

I did notice on my ~2k km trip signs for photo radar. A few times I noticed a pole with a horizontal overhang (another pole) with what appeared to be 2 sensors and a camera.  I was wondering if that was the photo radar and what might be the threshold for ticketing?

I think the speed limit was mostly 90km (Rt 1, 1102, 106...) and mostly I stayed under 110 but last ride I was nearer 120-25 when I passed one.... (kidding, of course....). 

I wonder if they take a photo of driver, license plate, etc. and I assume if they do ticket it will go to the rental agency who will then pass on the cost to me?

Just curious about it all... are they operable,  what might be the km-over threshold (and maybe it varies by the speed limit), possible cost, etc.)...?

Thanks.

Regardless of the speed limit, if you're over it, you're speeding.

Fines can be levied up to 4,000 BHT, but usually 500 BHT.
