You know I love a little word play, and "sharrows" might just be my new favorite portmanteau.
I have seen these arrows on the road for years but learned their formal name this morning listening to a radio program about San Francisco's new bike plan. Which sounds awesome, by the way! The share-the-road-arrows are painted on the road to help guide cyclists through designated routes and demarcate bike lanes. They also act as a visual reminder for drivers to share the road and to look out for cyclists.
