Always on fog lights?

[sub]

You mean startling a deer with bright lights so that you’re sure you can hit?

By the way to answer your question, it’s illegal in pretty much all states (either written plainly in the law or creating lumen and direction limitations). A quick Google search will tell you but here is some info:

None of those laws would apply to fog lights. Fog lights are not the same as light bar.

Posting OFF-ROAD light regulations doesn't really apply to OEM fog/driving lights.

You guys need to read the rest of the thread to know why I put this here. That being said you’re correct, it was not the principal subject of this conversation.
Overall just pointing out that people don’t love being blinded by others when driving.
Maybe Toyota doesn’t have DRLs and uses. Fog lights instead?

Toyota delivers vehicles in Oregon that allow you to have your fog/driving lights come on automatically when low-beams are on.

And they shouldn't.

I owned a 2005 Toyota Tundra that had DRL and fog lights. Fog lights switch could be turned on or off, and when "on" were linked to the low-beams. Setting persisted between engine cycles, too. DRLs couldn't be disabled.

Oregon does. Oregon treats fog lights the same as using your high beams. As do many states.

Not from what I could find in statutes. Oregon requires that "within 500 feet, the driver must use a distribution of light or composite beam so aimed that the glaring rays are not projected into the eyes of the oncoming driver." The DOT has issued advisories that fog lights must be dimmed for oncoming traffic, but the statutes don't seem to back that up outside of the vague (and likely unenforceable) requirement that "glaring rays are not projected into the eyes of the oncoming driver."

And they shouldn't.

Why not? Please provide law/regulation to back up that claim.

If you are referring to Oregon Revised Statutes Oregon Vehicle Code § 811.515, I cannot find in that would forbid 24/7 use of fog lights.

• It forbids the use of more than 4 headlights. 2 normal lights + 2 fog lights = 4.
• It forbids spotlights, which would not include a fog light.
• It forbids lights placed higher than 54" off the ground. Fog lights are closer to 12" than 54".
• It also forbids some lights that project a beem more than 75 feet from the vehicle. The procedure for aiming a fog lights is to park 25 ft from a wall and adjust the lights so that the beam is 4" up the wall. As long as the light bulb is at least 12" off the ground. 12"/4" x 25' = 75'. If the light bulb is located higher than 12", then the beam would make it even less far. So a fog light that has been adjusted to this standard will not project more than 75 ft. The choice of 75' in this section, when that is the exact distance that fog lights are calibrated to, seems to imply they were specifically trying to say that fog lights are OK.

So none of those apply to fog lights.

can someone take a pic of what the front and especially the rear fog lights look like on?

thanks in advance!

Probably should install a 48” light bar too and leave it on all the time. Not annoying at all for other drivers ?

Rivian should program them so they automatically switch off if there is oncoming traffic. Most people don’t use them because they are effective but because they think they look cool. Never minding blindly oncoming traffic.

Came here looking for this, is the guide the official way to submit requests for features?

All the SUVs I have owned recently will allow you to have auto headlights with or without the fogs and then when the high beams come on manually or automatically it turns the fogs off.
