I've been riding for about 2 years now and have given my fair share of motorcycle waves, but this one seemed different.

He extended his arm waist high and made small circle with it. Then about 100 yards up the road there was a cop. Was he trying to warn me? Are there different "waves" ???

 

I'm betting that you missed the first part of the "wave." I gaurentee he did a "5-0."

 

Usually, the sign for a police car is tapping of the top of the helmet.. I've seen it done a few times... (and returned the favor)

 

I know only about tapping on the helmet. I didn't get what it was about at first, but then figured pretty quick

 

up tapping the top of the helmet is what I'm use to too.

 

he was signalling for you to slow down

up and down or circley type hand signals is normally always 'slow down' and in this case rightly so as there was a copper up the road

 

ive only been signaled at once and it was because there was a cop up ahead, me and my buddy were going around a cornier and a couple guys on bikes were coming towards us, the guy in from put his hand out palm facing down and moved it up and down towards the ground, it was an obvious signal to slow down

 

I've seen both, slow down, and tapping the top of the helmet to signal for a cop. It's the nice world we live in that motorcyclists can and will signal, but cagers can't/don't.

 

Helmet tap FTW. Had some pretty funny moments involving the helmet tap signal at non-riding times. And also passing the cop that was warned about and watching him tap his head and laugh as a bunch of bikes go by, haha.
