    I don’t understand this at all. Why do I, as a person in front of a vehicle, care whether or not it’s braking?

      Say you’re a pedestrian and a car is coming toward you as you’re entering a crosswalk. Being able to see if they are braking or not could save your life.

        Ah. I see. They are emitting a green light, so I know they’re braking, and it’s OK to cross.

        But, it turns out that they’re planning on turning into a driveway past the intersection, and not into the intersection I am crossing.

        That’s OK. I can check “impersonate a hood ornament” off my bucket list.


        We already have this problem with turn signals: there are circumstances where it would be confusing and dangerous to use them in the manner prescribed by law, and to avoid dangerous ambiguity, they should actually be used much later than the law specifies.

        If a car is braking it rides differently from one that isn’t. A car is normally rather level and leans “forward” when braking.

        Besides that, YOU SHOULDNT GET IN FRONT OF ANYTHING YOU ARENT SURE IS STOPPING. If it’s moving fast enough that you need this, you shouldn’t be trying to get in front anyways.

          YOU SHOULDNT GET IN FRONT OF ANYTHING YOU ARENT SURE IS STOPPING

          This, exactly. This “plan” sounds terrible to me.

          No, I’m not braking to turn at the intersection you’re sitting in. I’m turning into a driveway just past that intersection. If you pull in front of the green light the government says I have to have on my vehicle, I’m going to t-bone you.

            Again, if you’re too stupid to make sure the multiton hunk of metal is coming to a stop by all the other obvious visual markers, including watching it’s speed compared to stationary objects like signs and lamp posts, then this won’t do shit. People need more aweness of their surroundings, not a bunch of lights and horns because people won’t pay attention.

            You enter the road when it’s safe, not jump in and play frogger with lights hoping to get across.

      for example, say you are waiting to make a left turn, it would be nice to know if oncoming cars are braking or not. if they are stopped and you see their brake lights turning off, you can judge if you should hurry up or not turn at all.

      The key detail is that, like with rear brake lights, they extinguish when the foot is removed from the brake pedal. So it’s not so much the presence of the brake light, but the presence of an inactive brake light that would, serve as a warning that a car is about to start moving. This would be very helpful to drivers on a road when other drivers are pulling out too early from a side road or driveway. That little bit of extra warning is, in many situations, enough for you to pump the brakes, hit the horn, or both.

        If anything I think they would have to use a green light that turns on when accelerating/not braking. It would be way more dangerous in the future when people are trained with “No green = braking” but older cars don’t have the light at all.
        It’s important to consider how a transition like this would even work. I personally think this is a little too drastic of a change, and is incompatible with existing vehicles and habits.

        I get what you’re saying — so it’s about the subconscious awareness of the state change that happens after the driver decided to go, but before the car starts moving. I can see some amount of value in that.

        I still can’t help but think it’s going to be interpreted by many as a sign that it’s safe to proceed and ignore the car rather than be prepared for any eventuality, though.

      Sounds like it can help oncoming traffic as well as traffic to either side of the vehicle

        Yeah, the only thing I could think of is that I’m driving down a country road, and I see the front brake light ahead of me because someone stopped for a deer in the road or something.

        Otherwise I cannot fathom what benefit it brings. Anything that ultimately becomes “if you see this light, it’s safe to [X] in front of this vehicle” is going to get people killed.

        And the negative state of “the lack of this light means that the vehicle could be moving” is exactly what we have now.

          Reading through the article, it seems like one scenario is that a vehicle stopped at an intersection might be about to pull out, endangering another vehicle about to cross? It seems like the thinking is, if you notice a front/side brake light stops being lit as you approach the intersection, it might indicate they’re about to accelerate - be cautious!

          I’m not fully convinced either, it seems like a lot of the benefit they’re projecting is based on analysis of historical collisions, rather than any kind of experimental results. It sounds like the study is to justify expanding research to that sort of simulated experimentation, though - I’m curious what that kind of testing would find.

          I feel that in my area the driving culture has become so toxic that there’s a better than average chance that indicating a lane change (which I always do) will lead to the vehicle in the lane you’re attempting to change into accelerating to prevent you from ‘getting in front of them.’
          It’s so frustrating (and dangerous!). It seems that a lot of folks feel entitled to the road, or the patch of road in front of their car fro as long as the eye can see, and are willing to behave irrationally regarding it.

          I feel that telegraphing that your vehicle is slowing down (for any purpose) will lead to overconfidence or even willful misunderstanding by other drivers. A careful slow-down will turn to panic as they try to take advantage of the situation. I also think that drivers will focus on the vehicles too much, and will not focus on things like pedestrians or perhaps why your car is slowing down, and wind up contributing to the problem.

      My main thoughts instantly come to someone in the opposing left turn lane, if they are not applying the brakes they are likely starting to turn and if they do it right in front of you, you have more of a heads up than just them starting to turn and can set yourself in a better position to hopefully stop in time. Driving is all about judgment calls and having more info quicker is important to those calls.

        But isn’t that exactly the situation we’re in now? If there’s a car in the opposing left turn lane, they might start to turn in front of you.

        The only thing the light does is say “right now, they’re braking”. It doesn’t say whether they’re moving or stationary any more than the headlights, and it doesn’t say anything about their intentions or whether it’s safe to enter the intersection.

      Yeah, and then you have the distraction of people looking in the mirror because of lights behind them. Especially seeing lights behind you at night thinking it’s a police car
