Warning signs: key rules to remember

Warning signs (Ch. 2 Traffic Controls)

  • Warning signs give advance notice of possible hazards on or near the road.
  • Three kinds: advance warning of a traffic rule ahead; physical features or conditions of the road; intermittent or moving hazards that may need a response.
  • Examples of advance warning: stop ahead, yield ahead, traffic control signals ahead, school bus stop ahead.

Signal advance warning with two lights; turn and curve signs; crossings

  • Some signalized intersections have an advance sign with two lights. When its lights flash, the signal ahead is red or amber or about to become red or amber: be prepared to stop.
  • Turn/curve signs: single turn right/left, curve right/left, reverse turn, reverse curve, winding road.
  • A speed plate under a curve sign gives the recommended maximum speed for that curve in ideal conditions.
  • Crossing warnings: pedestrian crossing ahead, animal crossing, moose crossing, bicycle crossing ahead, motorized snow vehicles crossing, school crosswalk ahead.

Intersections, converging and narrow roadways

  • Intersection warnings: concealed road (left/right), T intersection, Y intersection, railway crossing ahead, trucks entering from the right, dead end.
  • Converging roadways: merging traffic; added lane (free flow).
  • Narrow roadways: road narrows (both sides, left, right), narrow passage.

Lane ends, divided highway, other road conditions

  • Lane ends: loss of the left lane or the right lane.
  • Divided highway begins / divided highway ends.
  • Other conditions: hill, bump, pavement ends, slippery when wet, hazard marker (object on the right or left), pass on either side of an obstacle, rumble strips, falling rocks, chevron (change in road alignment), traffic light ahead, two-way traffic ahead.
