What Are Warning Traffic Signs (Red-White)?
Warning traffic signs use red-white striped backgrounds to alert drivers to hazards, obstacles, and road changes ahead. Unlike mandatory signs, they inform rather than command.
Warning signs are red-white striped and alert drivers to hazards: construction zones, lane closures, sharp curves, pedestrian crossings, slippery roads, falling rocks, and narrow bridges. Reduce speed and stay alert.

Step-by-step worked examples
Red-white striped sign shows construction ahead. Speed limit was 90 km/h. What do you do?
Sign type: warning (red-white striped) Hazard: construction zone Action: REDUCE speed, expect lane changes and workers New speed: 40–60 km/h (per signs), or flow of traffic
A driver ignores a pedestrian-crossing warning sign and maintains high speed. What is the risk?
Sign: pedestrian crossing (red-white) Driver action: ignores, maintains speed Risk: pedestrian steps into path without warning Consequence: collision, injury, legal liability
Slippery road warning (red-white chevron or wet symbol). Conditions ahead?
Sign type: warning (red-white) Hazard: wet surface, ice, or loose gravel Action: increase following distance (3+ car lengths), gentle braking Speed: reduce to safe level for conditions

Common mistakes
Warning signs are optional; I can ignore them if I see no immediate danger. — Correct: Warning signs alert you to conditions you may not see. They must be respected.
A pedestrian-crossing warning doesn't apply if no pedestrians are visible. — Correct: Pedestrians can appear suddenly. Warnings stay in effect always.
Slippery-road warnings only apply in winter or rain. — Correct: Slippery surfaces (ice, gravel, wet leaves) can occur anytime. Check conditions after warning signs.
Warning signs suggest slowing down, but it's not mandatory. — Correct: While not a command like blue signs, warnings indicate real hazards. Ignoring risks fines and crashes.
FAQ
What are warning traffic signs?
Warning signs are red-white striped and alert you to hazards, obstacles, and road changes ahead. They inform, not command.
What should you do when you see a warning sign?
Reduce speed, increase alertness, and prepare for the hazard indicated (curves, construction, pedestrians, slippery surface).
Can warning signs be ignored in light traffic?
No — traffic volume doesn't change the hazard. A slippery road or sharp curve is dangerous regardless of traffic.
Difference between warning (red-white) and mandatory (blue) signs?
Blue signs command action you must follow. Red-white signs warn of hazards requiring you to react (slow down, stay alert).
