Page 35: Warning signs

Our summary · page 35

Warning signs show where the road narrows or a lane ends, and where a divided highway begins or ends.
Others warn about the road surface: slippery when wet, bridge ices, bumps, pavement ends, falling rock.
Shared-use signs: give cyclists space, or expect them to use the full lane where it’s too narrow to share.
