With the first hay cuttings made, some of us are thinking about summer vacation. If you don't take a real vacation any more often than I do, some planning probably is called for.

Before you hit the highway, you may want to review some rules of the road; how you will get from here to there. To that end, we have prepared a multiple-choice automotive exam. Ready? Books closed! Begin.

1. The speed limit on rural interstate highways is:
   1. Higher than in school zones;
   2. Ten m.p.h. slower than you were doing when you passed that highway patrolman;
   3. Redundant, because the pavement is under construction.
      
      
2. When driving in heavy rain, you should be aware that your vehicle:
   1. Will need its windshield cleaned;
   2. Begins to believe it is a boat;
   3. Gets wet.
      
      
3. How far can you drive while the kids in the back seat sing all the verses to "Ninety-Nine Bottles of Beer on the Wall?"
   1. From here to Pocahontas, Ark.;
   2. From Columbia, Mo., to Sioux City, Iowa;
   3. Only to "Forty-Three Bottles" before you stop the car and order them to get out and walk.
      
      
4. When being passed by a large semi-trailer, you should:
   1. Try to read all those little licenseplates on the rear of the truck;
   2. Realize that the mass of metal may temporarily interfere with radio reception;
   3. Wave and gesture, to try to get the driver to sound his air horns.
      
      
5. The mileage added in the first year to the average family's new car is:
   1. Six thousand miles above average;
   2. A surprise to the registered owner;
   3. Enough to make the warranty expire.
      
      
6. When driving into the harsh glare of sunset, you should:
   1. Close your eyes;
   2. Turn around and drive in the opposite direction until after sundown;
   3. Let your spouse drive.
      
      
7. In automotive history, Henry Ford is best remembered as:
   1. The man who built Detroit;
   2. The inventor of chrome;
   3. The man who succeeded Richard Nixon as president.
