I don't see the option

I am in Sao Paolo currently, and I have the latest version of Waze on my phone. I cannot find this option in my Waze. Could you please help?

Recientemente Waze me sugirió una ruta de viaje de un solo carril, llena de curvas y muy peligrosa por la sierra, aunque en distancia era mas corta hubiera preferido una ruta alternativa con autopista aunque fuera con peaje, ojala pudiera alertar sobre esto.......o dar alternativas

If you actually need the road fixed ("no left turn"), go to Waze.com, create an account, and flag the issue for review; or, take the turn once yourself, then flag the directions as being incorrect.

you could personally flag that road as dangerous, or routinely place hazard markers on it, or post that the speed is reduced to 5mph. That would cause the routing algorithm to unprefer that road. Alternatively, see if you can edit the road to be broken in the middle or local-only.

You are sending traffic down Old Priest Grade off Hwy 120. You are sending RV's, drunks, teens, the elderly down the steepest road in California, no side rails. Incredibly dangerous. Not only that, but to make that left turn heading east, there is no turn lane and you are directing traffic across the highway on a curve.

See above

Waze should let users mark intersections where heavy traffic makes turning left or going through it as Waze directs hazardous or impossible. A turn that makes sense off peak may cause an accident if attempted at rush hour. Conversely, crossing a busy boulevard with six lanes of traffic at an uncontrolled intersection at rush hour may be possible, but only if one waits ten minutes

We live in an area with very dangerous roads that are single lane mostly. Passing in the opposite direction is usually negotiated with a cliff next to you. It is the ONLY way in or out for emergency vehicles. Today we had endless stopped traffic from teh beach. There are at least two places with active slides that could close the road for months.

Sugiro que em conjunto com orgãos de trânsito e segurança, seja criado uma forma a se evitar zonas perigosas, como já existem para pedágios e ruas sem pavimentação.
