Permalink Reply by Justin Morrison on April 22, 2011 at 9:55am Glad you posted this because I had a similar experience last week up here in SF, riding into the city after rush hour at 85. Oncoming traffic was blocked and I saw a stationary rider tapping the top of his helmet. I slowed and reached for the top of my helmet, then looked around the bike, thinking I had something coming undone. Then I saw the cop hiding out under the overpass and was glad I'd slowed already. ha!
I'd never heard of this signal before now.
