Yea..... depends on the Police Chief's orders from the Mayor's office.
In California, there is the Highway Patrol "11 99" Foundation that supports crisis for Trooper members & families. Decals & license plates. ( Saved my ass 3 times)
Florida I have the 'Florida Sheriff's Association' that supports Sheriff Youth Ranches. I have a decal next to my rear plate ( Florida does not require a front plate).
These are sort of a "Get Out of Jail Card" for the small stuff.... They won't even pull you over.
Here's a traditional ( and friendly) good-guy / I'm on your side..... To avoid a radar pointed at you....
Left hand on steering wheel....
You see a Cop, Sheriff or Fireman driving toward you... Left palm on steering wheel....
Open your hand wide showing your whole hand as a wave hello ( palm on wheel)..
99.99 % of the time they will wave back the same way. This is usually because you or family is law enforcement.
I do it all the time by habit. ..Automatic....
If a radar is pointed straight at you and you do the 'hello wave', they actually see that, and the radar lowers, and they wave back.
Having said that,... I truly "have their back"....
But it does work. I haven't had a ticket of any kind in 25 years. ( My dad was a cop)
