Warning signs

  • Diamond shape, yellow background, black letters/symbols; warn of dangerous or unusual conditions (slippery roads, sharp turns, trucks turning, dips). No other sign has this shape.
  • Pedestrians may be crossing; winding road; bump or rough road; right lane ending; steep hill (may need lower gear and engine braking); traffic lights ahead; clearance under a bridge/overpass; right turn followed by left turn; two lanes merge with traffic entering from the right; pavement ends, gravel road ahead.

Warning signs

  • Intersection ahead crossing at right angles; playground (watch for children); railway crossing ahead; falling rocks; sudden turn in direction of arrow (slow down); moose regularly cross this section (slow down, caution); narrow bridge or underpass; dead end (exit right or left); two-way traffic ahead (share the highway); sharp curve to the right; slippery when wet; stop sign ahead (be prepared to stop).

Warning signs

  • Two roads converge, merging not required (added lane).
  • Divided highway ahead (median/island): keep right; signal and change lanes only when safe.
  • T-intersection ahead: go right or left.
  • Road ahead is narrower than the road you are on.
  • Slight bend or curve ahead.
  • Divided highway ends: single roadway with two-way traffic ahead; keep right.
  • Roundabout ahead: slow down; may show recommended speed.
  • Sharp turn in direction of the symbol.
  • Slow-moving vehicle sign: required on the rear of the vehicle when driven on the highway.

Hazardous conditions signs (weather)

  • Advisory messages or road closures/detours for bad weather; black on yellow (with or without yellow flashing lights) or digital with yellow/orange lettering on black.
  • Obey them strictly. Examples: wind warnings in the Wreckhouse area; closure of the highway from Holyrood to St. John's in winter weather.
