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 warning sign alerts drivers that slippery road conditions are possible ahead, advising them to slow down and proceed with caution. The options referring to a car wash or a bumpy road are incorrect because a car wash is not a standard highway hazard, and a bumpy road has its own distinct double-bump symbol. While hydroplaning is a hazard on wet roads, the official ICBC designation specifically labels this icon as slippery road conditions. Under BC Motor Vehicle Act guidelines, yellow diamond-shaped signs warn of physical road hazards. Memorizing these standard hazard signs is essential for passing the ICBC knowledge test and adjusting speed safely in real-world driving.
