A bit of helpful information. If the cruise control turns off when you use the turn signal, you have a bad turn signal bulb.
A bit of information,a burned turn signal bulb will cause your turn signal to blink faster,did you notice faster blinking?
I’ve seen cars like that before, but are you sure all cars and trucks have that feature?
It would most likely depend on the flasher design,a bi-metaltic unit as opposed to a electronic module.
So the answer is no,I cannot say all respond this way.
Why are the turn signals and the cruise control in use at the same time?
Probably changing lanes on the highway.
