  **Question               
  A**                      

               F     1\.   The tractor driver can't see anything behind the hay
                           wagon because it blocks his view.

               F     2\.   The noise of the tractor engine drowns out sounds of
                           vehicles approaching from behind.

  T                  3\.   The hay wagon blocks his view. The tractor driver can't
                           see your car approaching from behind.

               F     4\.   Risky! You should not assume the tractor driver would
                           hear the horn. The tractor engine is very loud. Also,
                           many farmers have hearing loss from years of working
                           around loud noise.

  **Question               
  B**                      

               F     5\.   The tractor and hay wagon may turn into the driveway on
                           the left and block the road.

  T                  6\.   If the tractor turns left into the farmyard driveway it
                           and the hay wagon will block the whole road.

               F     7\.   The tractor driver may not hear your horn over the
                           tractor engine noise.

               F     8\.   Increasing your speed will give you less time to react
                           and stop if the tractor turns left into the driveway.

  **Question                
  C**                       

  T                  9\.    The driveway on the left that leads into a farmyard
                            should alert you that the tractor and wagon might turn
                            left.

  T                  10\.   The farm on the left might not be where the farmer is
                            going.

  T                  11\.   When pulling loads, tractors will slow down and may
                            stop to shift into a lower gear before turning into a
                            driveway.

|     | F  | 1 | You don't have enough time. A distance of 5 car      |
|     |    | 2 | lengths is about 90 feet. You are traveling 65mph or |
|     |    | \ | 95 ft/sec. It takes the average person about 1       |
|     |    | . | second to react, get their foot on the brake pedal,  |
|     |    |   | and apply the brakes. After the brake pedal is       |
|     |    |   | pushed the car will travel an additional ½ second    |
|     |    |   | and 47.5 feet before its braking system fully        |
|     |    |   | engages. Thus the car will travel 143 feet before it |
|     |    |   | starts to slow down. Then, even on a dry road, a car |
|     |    |   | with good brakes and tires travels another 202 feet  |
|     |    |   | before it can stop. The reaction distance and        |
|     |    |   | stopping distance add up to 345 feet. Your car will  |
|     |    |   | hit the tractor at full speed. (See the attached     |
|     |    |   | table from the following web site.)                  |

|     | F  | 1 | The tractor and wagon block the path to the left.    |
|     |    | 3 |                                                      |

+-----+----+---+------------------------------------------------------+
|     | F  | 1 | The tractor and wagon block the entire road. If you  |
|     |    | 4 | steer to the right of the wagon you could run into a |
|     |    | \ | ditch, trees, fence posts, and telephone poles.      |
|     |    | . |                                                      |
+-----+----+---+------------------------------------------------------+
| T   |    | 1 | You can't avoid a collision. If you had immediately  |
|     |    | 5 | hit the brakes when you topped the hill at 65 mph    |
|     |    | \ | and saw the hay wagon, your car would travel 143     |
|     |    | . | feet before the brakes started slowing it down, and  |
|     |    |   | another 202 feet to come to a stop. During the fist  |
|     |    |   | second of this time, if the tractor was traveling at |
|     |    |   | 12 mph, it would have moved ahead about 18 feet.     |
|     |    |   | Because your car is slowing down you might be able   |
|     |    |   | to avoid a collision, but it would be close.         |

  **Question                
  E**                       

               F     16\.   You can't stop. You don't have enough time to react,
                            step on the brakes, or slow down. See the answer for
                            item 12.

  **Question                
  F**                       

  T                  17\.   When the tractor driver turned left into the driveway
                            it was too late for him to do anything to prevent the
                            crash.

  T                  18\.   Before he hauled the hay wagon on the road, the farmer
                            could have asked a friend to drive his car behind the
                            wagon. His friend could have used the car's flashers
                            and left turn signal to alert other drivers that the
                            tractor and wagon were about to turn left into the
                            driveway.

               F     19\.   Drivers behind the tractor and fully loaded wagon
                            can't see the tractor driver or his hand signals.

               F     20\.   The tractor driver can't make eye contact with the
                            driver (you) because the fully loaded wagon blocks his
                            view.

  **Question                
  G**                       

               F     21\.   This is risky because the tractor driver can't see or
                            hear you. If the tractor turns left you will crash.
                            See the answer to item 12.

  T                  22\.   You probably could have avoided the collision. See the
                            answers to items 12 and 15. The best way to avoid
                            collisions like this one is to stay alert and obey the
                            posted speed limit.

               F     23\.   The tractor driver can't see or hear you. The loaded
                            hay wagon blocks his view. The full hay wagon plus the
                            tractor engine noise drown out the noise of your car's
                            horn.

               F     24\.   Too late! You are going too fast to avoid a collision.
                            You will strike the tractor and wagon at full speed.
                            See the answer to item 12.

  **Question                
  H**                       

  T                  25\.   Fog can quickly become very thick and decrease
                            visibility.

  T                  26\.   Tractors often pull discs, plows, and mowers that are
                            wider than one lane and that are difficult to pass on
                            narrow roads.

  T                  27\.   Not all tractors have lights and slow moving vehicle
                            (SMV) signs that are highly visible. About 80% of
                            after dark collisions occur when motor vehicles
                            rear-end tractors or equipment being pulled by the
                            tractor.

  T                  28\.   If you can't see what's on the other side of the bend,
                            it is best to slow down until you can see what's
                            ahead. With your foot on the brake pedal it also takes
                            less time to stop if something is in the road ahead of
                            you.

  **Question                
  I**                       

               F     29\.   Tractors and hay wagons travel much slower than the
                            posted speed limit.

               F     30\.   Tractors and hay wagons travel much slower than this.

               F     31\.   A typical farm tractor can reach these speeds, but not
                            when pulling a loaded hay wagon on a winding and hilly
                            two-lane country road.

  T                  32\.   Tractors pulling hay wagons and other large equipment
                            on rural roads rarely travel more than 12 mph.

  **Question                
  J**                       

               F     33\.   48 ft/sec = almost 33mph

               F     34\.   62 ft/sec = about 42mph

  T                  35\.   There are 60 minutes in an hour. A mile is 5,280 feet.
                            A car traveling 60 mph travels a mile every minute.
                            There are 60 seconds in a minute. Therefore, a car
                            traveling 60 mph is moving at 5,280 ft/60 sec = 88
                            feet/second.

               F     36\.   If a car traveling 60 mph travels 88 feet in one
                            second, how many ft/sec would it travel at 1 mph?
                            (Answer: It would travel at 1/60^th^ x 88 ft/sec =
                            88/60 = 1.467 ft/sec.) Now that you know 1 mph = 1.467
                            ft/sec you can calculate the feet per second for any
                            mph velocity. For example, at 95 mph a car travels
                            139.4 ft/sec (1.467 ft/sec x 95 = 139.4 ft/sec).
