a turn too far

What is a driver to do when faced with contradictory direction? Can you get a ticket if you were following the clear instructions on a sign, but disobeying the (less visually obvious) instruction painted on the pavement?

This photo was taken facing South on Homelawn Street / Utopia Parkway, under the Grand Central Parkway overpass. There are two southbound lanes.

Notice that the physical metal sign indicates that you can make a left turn from the right lane. But the directions painted on the street indicate that the right lane is only for going straight.

So, with contradictory directions, which signs govern?

Certainly, the prudent course for a driver who wants to avoid tickets is to obey the street-painted instructions (i.e., to treat the right lane as a straight-only one), since that way you're obeying both traffic control devices (as I believe they are called).

But what if someone sees the sign and not the street painting, and makes the left turn from the right lane? Can he get a ticket? Can he successfully fight the ticket on the grounds that there's a sign that explicitly says he can do what he did?

But, more fundamental than a ticket is the question of safety. I can see a situation where someone in a  hurry uses the left lane to go straight to save time. Noting the street-painted sign (and missing the metal one), he thinks that no one will turn left from the right lane. It would be an illegal straight, but let's not pretend people don't do that kind of thing. At the same time, someone makes the left turn from the right lane. Accidents will happen. The combination of signs makes it more likely.

I'm not sure whether I'd prefer that they allow or disallow the left turn from right lane. But I do know that I'd like them to make a decision and have their signage agree.
