Brake lights

When driving on the interstate I always use dynamic radar cruise control, letting the truck keep me at a safe distance from the vehicle in front of me, but I started wondering yesterday if, while slowing me down, the truck is also actuating the brake lights. I’m sure it does (I think ) but does anyone know for sure?

 

I’ve been wondering this myself… do I look like that driver that’s always tapping on the brakes every two seconds . Staying safe if they do come on I guess.

 

Yep, they come on.

 

Is this how it works/looks?

There aren't many more infuriating things on the road than being stuck behind someone who's brakes come on and off every few secs (or just frequently) for no apparent reason.
.......makes you wanna drive them off the road, if only to regain some sanity.

I just wish they gave all the models the sequential turn signal like they first advertised
