Road Signs
You are driving at 80 km/h on a rural road. You see a yellow diamond sign with a curved arrow. What is the best response?
Show Answer & Explanation
Correct Answer: B. Slow down before reaching the curve to match safe cornering speed
The safest technique for a curve is to slow BEFORE entering it, then maintain steady speed through. Braking inside a curve can cause weight transfer and loss of traction. The advance warning sign exists precisely so you can adjust speed in the straight section before the curve begins.
Why the other answers are wrong
- A.Maintain speed since warning signs have no legal forceWhile warning signs do not impose a legal speed, ignoring them often leads to single-vehicle collisions — slowing is the correct response.
- C.Brake heavily inside the curveHeavy braking inside a curve transfers weight forward and can cause loss of traction or skidding; brake before, not during.
- D.Pass any vehicle in front of you while the road is straightWarning signs may appear in no-passing zones; passing through a warning area is often posted as unsafe or prohibited.
