Do Semi Trucks have a special means of flashing their lights to other trucks merging over?

Question

When a truck signals to another truck on the highway that they are clear to move over in front of them - do they have a switch or something easier to use than what cars use to turn on and off the lights? I ask because I hate to think they take their hand off the wheel or other manuver to go to all that effort...

Answer 1

Some trucks have a momentary flasher - either a foot pedal or button.

Others just have to take their hand off the wheel and flick the switch twice - it's not exactly as much effort as you make it out to be.

Answer 2

Yes...its a interrupt switch to the maker ( indicator lights) they are in different places depending on the brand of truck...

Peterbilt vs frieghtliner vs Volvo...to mention a couple all have them ...the switch is located in different areas in each truck.

and there is no effort to flash a thankyou to other truckers ..and even some cars....i do it all the time.

Answer 3

The Flashing of their lights is a Warning that their is police car a hear, or an accident,or they are carrion a heavy load move out of their way the load is pushing the truck they can't stop like a car can and if you move out of the trucks way or let them merge in your lane they flash their lights to say thank you.

Answer 4
