I've never heard of the helmet tap. Never even though about warning people on bikes for cops, but I'm guessing I'd flash my lights like with a car.

[BUCKJFLOWERS]

They are not a big fan of letting people know they are sitting there waiting haha that was nice though

so you dont warn people about cops that is just mean =)~

twirly-finger or the ol' helmet tap. Most people around here know either/or.

[Robgsxf750]

Left hand off the handlebar in a nazi-style salute and move it up and down - probably the same as gytrdunkat.

Yup, another Headbanger here too

Hmm. I havn't seen the helmet tap yet. Here in SC we use the flashing light technique during the day. At night I think you are just fair game for the pokeys lol

Now....if we are all obeying the law, we wouldn't be thinking of "what does that signal mean??"

[SchOX]

Here it is left palm shown to the other biker, or slow down signal, like "a slow motion basketball player".
Tap on the helmet suggests "stupid"?

[ansobu]

In Ohio I see a lot of the twirl in the air...but going south to NC I've seen the tap. Really must be a regional thing.

Helmet for the popo, slow down for anything else, like wildlife or debris.

[DreKat]

the head tap here means that there is something on the road that could be dangerous

[LAsunbird86]

never seen the helmet taps, but I usually twirl my finger in the air to warn for cops.

[soulpatch]

I do a little of everything to try to get the point across......
