  2. On a road with a 35 mph speed limit, how far before a turn does Iowa law require you to signal?

    • A At least 50 feet
    • B At least 100 feet
    • C At least 200 feet
    • D At least 300 feet
    Show answer

    B. At least 100 feet

    Iowa requires a turn signal at least 100 feet before the turn when the speed limit is 45 mph or less. On faster roads the distance goes up to 300 feet, because traffic needs more time to react.

    On a two-lane road, the center line has a solid yellow line on your side and a broken yellow line on the other side. May you pass?

    • A No, because the solid line is on your side
    • B Yes, if no oncoming car is in sight
    • C Yes, but only to pass a slow farm vehicle
    • D No, and the other side cannot pass either
    Show answer

    A. No, because the solid line is on your side

    When a solid and a broken yellow line run together, the line nearest you decides. A solid line on your side means no passing, while drivers with the broken line on their side may pass when safe.
