It's an older article and might need further updating. You can also check whether it is coded as illegal in your state.

The practice, common among motorists, of flashing headlights to alert other drivers to an upcoming patrol car has been claimed as a form of expression protected under the free speech clause of the First Amendment. Thus far, courts have generally interpreted the practice as protected free speech.

Now there's waze.

Cops monitor Waze. They also post fake cop warnings at places to try to get drivers to slow down.

99% of cops are marked on waze. The other 1% is found by my radar detector. Around here state troopers run radar wide open and can see them from a couple miles away. Waze are good for the fuckers shooting laser and only if you're on a main road that sees volume.

Oh, I agree and I use Waze just for that same purpose. My radar detector doesn't catch everything. I was just pointing out that cops will also try to game the system, which is why if I see an alert where there's no cop I update it.

I love you. Most people are completely unaware of what it takes to avoid cops and the tools at our disposal these days.

1 Situational awareness

2 Radar detectors (and being aware of their downfalls)

3 Waze and other apps that alert to police presence

4 What other drivers are generally doing in front of you(Falls in with situational awareness)

A number of years ago a friend of mine got stopped by the cops for flashing his lights as a warning. He didn't get a ticket, just a warning.

When I lived in NJ, I used to warn people of the hidden cops by flashing my lights all the time. I got a warning as well but that would have been late 90s early 2k.

I never got a ticket in Jersey but I did get pulled over a couple of times and warned for one thing or another. At a sobriety check, they stole my maglite claiming it was a weapon. I was so glad to get out of there.

In commiefornia the headlight flash is used when behind another car to mean: 'GTFO of MY fast lane!'

Yeah, flashing 'rolling roadblocks' from behind is universal.

Some jew (named in article) interpreted light flashing as "encouraging people to speed up, slow down then speed up". WTAF.
