By signaling to oncoming traffic and vehicles approaching from the side, a front brake light provides an essential visual cue that a car is slowing down or preparing to stop. When the light is extinguished, it indicates that a stationary vehicle might initiate movement. According to Tomasch, this visual feedback can significantly truncate the reaction time for other road users, leading to shorter stopping distances and consequently diminishing the likelihood of accidents.

Sounds reasonable. Personally I just want front turn signals to be visible from the opposite side again.

Not sure if I read that correctly, but I don't think this has ever been the case?

I think what he wants is the front turn signal to wrap around the front, so I can see the left signal from the right quarter.

I'm not aware that this is not the case, but I don't know that I would have noticed if it was not.

Isn't that the case for pretty much everything? Newer cars alternate blinking their headlights and the signal indicator, and even cars w/ the turn signal on the side will have some light bleed through since it's all one assembly. In the majority of cars, I can see their turn signals when they're perpendicular to me. The larger issue is that most people in my area don't bother to use their signals in the first place.

[–] SaltSong@startrek.website 1 points 2 weeks ago (1 children)

Yea, that's part of why I don't know for sure if they make cars the way the guy at the top of this thread is describing.

[–] sugar_in_your_tea@sh.itjust.works 1 points 2 weeks ago (1 children)

Same. I don't think I've ever seen a car that can show me the signal on the opposite side of the car, but I have seen a lot of cars where I can see the indicator while stopped at an intersection and the car is perpendicular to me, since I have a little bit of angle to see the edge w/ the indicator.

99% of the time, it's not an issue, and the other 1% of the time it doesn't really matter if I can see the indicator (I.e. they're already halfway turning, so they're angled away from me).

[–] catloaf@lemm.ee 3 points 2 weeks ago

Yes that's all I want, to be able to see the indicator again. A lot of newer cars have moved them too far to the side of the vehicle.

I encounter this pretty often because a Boston area streets are terrible and the drivers are worse, so a visible indicator helps all drivers make traffic flow more smoothly.

i don't think that was ever required in the US. it is elsewhere though.

[–] SaltSong@startrek.website 5 points 2 weeks ago

Can't speak to "required." But I know it used to be done.

[–] Ghoelian@lemmy.dbzer0.com 1 points 2 weeks ago (1 children)

I'm pretty sure most cars have a turn signal near the headlights, and one on the mirror or on the side for that use case, no?

[–] Ghoelian@lemmy.dbzer0.com 1 points 2 weeks ago* (last edited 2 weeks ago)

Actually I think I remember watching a technology connections video about how card in the US can use the headlights as a turn signal, or something like that. I don't think that's allowed in Europe or the EU or whatever.
