Road Signs

A yellow diamond sign showing a car with wavy tracks behind the wheels means:

Ontario road sign — The road is slippery when wet — slow down and drive with caution
Show Answer & Explanation
Correct Answer: A. The road is slippery when wet — slow down and drive with caution

Slippery-when-wet warnings flag spots where water reduces friction dramatically — bridges, painted lines, oil-slicked intersections. Slowing in advance of these areas is essential because braking or sharp steering on a slippery surface can cause loss of control.

Why the other answers are wrong

  • B.A carwash is one kilometre aheadService signs (car wash, food, gas) are blue rectangles with service pictograms, not yellow diamonds.
  • C.Avoid using the windshield wipersWipers are unrelated to this sign; the sign's message is about road-surface friction.
  • D.The road has recently been pavedFreshly paved signs use orange diamonds because paving is a temporary construction condition, not a yellow warning.
