3 questions from the Arkansas practice test

  1. 1. How should you adjust your speed on packed snow, according to the Arkansas guide?

    1. Keep the posted speed
    2. Cut your speed in half
    3. Slow by 5 mph
    4. Speed up to keep momentum
    Show answer

    Cut your speed in half. On packed snow, the guide says to cut your speed in half, and on ice you must slow to a coast. Keeping the posted speed or slowing just 5 mph leaves far too little margin, and speeding up for momentum invites a skid. Slow down at the first sign of rain, snow, or sleet, and avoid driving on icy roads if possible.

  2. 2. What does an orange triangle bordered with red warn road users about?

    1. A vehicle traveling slower than normal traffic
    2. A vehicle carrying hazardous material
    3. A lane reserved for passing
    4. A railroad crossing with multiple tracks
    Show answer

    A vehicle traveling slower than normal traffic. The reflective orange triangle with a red border identifies a slow-moving vehicle. It warns approaching drivers to expect a large speed difference and to plan carefully before passing. The hazardous-material option describes a different concern, while the lane and railroad choices refer to roadway controls rather than a vehicle emblem. Seeing this symbol should prompt earlier awareness and a controlled approach instead of a sudden pass.

  3. 3. At night, about what speed lets you stop within the distance your headlights let you see ahead?

    1. Around 30 mph
    2. Around 50 mph
    3. Around 40 mph
    4. Around 65 mph
    Show answer

    Around 50 mph. Darkness makes objects harder to see, so at night you need to be able to stop within the distance your headlights light up. The Arkansas guide puts the speed that allows this at around 50 mph. Thirty mph is a different rule: it is the top speed the guide gives when rain or fog keeps you from seeing more than 200 feet ahead. Forty mph is lower than the figure stated, and 65 mph would carry you past what your lights show before you could stop. If you cannot see a safe distance ahead at your speed, slow down.
