Sorry if this has already been discussed (I really did search), but am I the only one NOT digging the autos with the headlight that turns off when the turn signal is on? Just reminds me of the driver that can't use a mirror properly and has to do a "Poltergeist" just to merge into another lane. Just my

 

I don't know, I always figured it was a dot rule to let the blinker stand out more.

As far as looking before you merge, I think that's also highway code. Hell I have a couple cars that don't even have mirrors on the passenger side.

 

Yeah I think it's dumb when I see a car with one DRL on and one turn signal flashing. It seems that only cars with LED DRL do this?

You are supposed to check your blind spot before you merge/change lanes.

 

Thank you OP for having the courage to finally address the elephant in the room.

Now if only someone would ban those stupid epileptic third brake lights.

 

This one's easy. I think its to avoid changes of head-on collision for example. I've found myself in the past especially in a dark road seeing a car on the other side of the yellow line stopped in the middle, turned a bit to its left (meaning towards my side of the road) and blinding me. turn signal becomes faint often not visible to understand that driver's intentions.

If his headlights are off I could see his turn signal clearly. that could be it.

 

The headlight turns off or just the DRL? I've never noticed that the headlight goes off but maybe I just don't do enough driving at night.

 

It's the DRL.

 

When DRLs were built with high intensity LEDs, someone smart enough to realize that may overpower a blinker decided to turn off the unnecessary light. If you knew what a DRL is for and what a blinker is for, you would understand. Function >>> Form when it comes to public safety.

They are technically illegal per USDOT laws which affect manufacturers and many state laws which affect owners. However, our society is so resistant to change that the laws are full of obsolete rules that drown or the worthwhile ones.

 

I literally had to get a letter from Chrysler Historical to get the state inspector to believe that my 93 jeep is exempt from the 3rd brake light.

 

I was referring to the ones that flash quickly before coming on every freaking time the brake riding idiot in the driver's seat brushes the brake pedal.

 

Those are annoying.

 

Did not know this. I see them a lot on commercial vehicles (cargo vans & such), some newer school buses too. Exemption?

 

This is exactly the reason. Call me crazy but I'd rather see a turn signal than have it overpowered by a DRL
