Driver's License Test Prep
New York Practice Speed Limits

The manual says roundabouts are designed so vehicle speed inside the circle is restricted to no more than:

  1. A.
    30 mph Correct
  2. B.
    20 mph
  3. C.
    25 mph
  4. D.
    40 mph
The Why

The answer is "30 mph"

Roundabouts are designed so all vehicle speeds inside the circle sit at 30 mph or less. Drivers who pick C are borrowing the 25 mph work zone floor printed elsewhere in the signs coverage and applying it to the roundabout paragraph.

Why the others miss

The traps in the wrong answers

B. 20 mph

The manual gives 30 mph or less, not 20, as the roundabout design speed. This answer treats a roundabout like a tight neighborhood corner rather than a through movement.

C. 25 mph

25 mph is not the ceiling the manual gives for the roundabout. This answer recalls the 25 mph work zone floor from a different chapter and applies it here.

D. 40 mph

40 mph is above the ceiling the manual sets for roundabout travel. This answer treats the circle like a normal through road rather than a curved yield movement.
