Question: What does a sign showing a car with wavy lines under it mean?

Answer options:

  • Car wash ahead ✅ Slippery road conditions possible
  • Bumpy road
  • Hydroplaning area

Correct answer: Slippery road conditions possible

Explanation: This yellow, diamond-shaped hazard sign alerts drivers that slippery road conditions are possible, typically when the pavement is wet or icy, warning them to reduce speed and avoid sudden maneuvers. Incorrect options like a bumpy road are represented by a different symbol showing two humps, whereas car wash and hydroplaning are simply incorrect interpretations of the depicted skid marks. Under SAAQ regulations, yellow warning signs advise of potential roadway hazards ahead to prompt proactive, defensive driving. Memorizing this and other standardized symbolic pictograms is highly relevant because sign identification constitutes a major, mandatory portion of the official written knowledge test.
