In plain language

When flying a Class C1 drone, you must plan your flight to avoid flying over any uninvolved people. If someone unexpectedly walks under your drone, you must fly away or land as quickly and safely as possible to minimize the overflight time. You must never fly over assemblies of people (crowds).

Requirement as structured

Operations with Class C1 unmanned aircraft must be conducted so that the remote pilot does not overfly assemblies of people, reasonably expects no uninvolved persons will be overflown, and minimizes overflight time if unexpected overflight occurs.
