Buddy, I found out that the fine for running a red light is pretty hefty. It's not just the money — R$ 293.47 — but mainly the 7 points you lose on your CNH. This is classified as a very serious infraction by the CTB, so the system doesn’t mess around with it.

What caught my attention is that there are some cases where you can pass without getting a fine. Like turning right at a signal, ambulance with siren on, those kinds of things. But most situations are pretty clear: when the light is red, you stop. End of story.

The (radars), those 'speed cameras', are getting smarter all the time. They catch when you actually run a red light, but they also record if you're standing on the crosswalk or speeding. It’s not just running a red light that they catch.

The cool part is that you can check everything online now. If you pay quickly, you get a discount. Here's a tip: slow down when you see the yellow light, because running a red light seriously jeopardizes your long-term driving rights. It’s not worth the risk.
