Questions that are easy to get wrong

Curve ahead

What does this sign mean?

  1. A gentle curve to the right ahead (Correct answer)
  2. A side road joins from the right ahead
  3. Right turns only from this lane
  4. A sharp right-angle turn ahead

Explanation: A curved arrow warns of a slight bend in the road. A right-angle arrow would warn of a sharp turn instead.

Sharp turn ahead

What does this sign mean?

  1. A gentle curve to the right ahead
  2. Right turns are allowed only at the next light
  3. The right lane ends ahead
  4. A sharp turn to the right ahead (Correct answer)

Explanation: The right-angle arrow means the road turns sharply. Slow down more than you would for an ordinary curve.

Curve ahead

Which best describes the road ahead when you see this sign?

  1. It ends, and you must turn right
  2. It bends gradually to the right (Correct answer)
  3. It splits into two one-way roads
  4. It turns at a right angle to the right

Explanation: This is the curve sign: the bend is gradual. Still slow down before the curve, not in it.
