  long, steep grades
          A skid happens whenever the tires
          lose their grip on the road. This is
              caused in one of four ways:
• Over-braking. Braking too hard and locking
  up the wheels. Skids also can occur when
  using the speed retarder when the road is
• Over-steering. Turning the wheels more
  sharply than the vehicle can turn.
• Over-acceleration. Supplying too much
  power to the drive wheels, causing them to
• Driving Too Fast. Most serious skids result
  from driving too fast for road conditions.
  Drivers who adjust their driving to conditions
  don't over-accelerate and don't have to
  over-brake or over-steer from too much
Drive-wheel Skids
• By far the most common skid is one in which the rear wheels lose traction through excessive braking or
    acceleration. Skids caused by acceleration usually happen on ice or snow. Taking your foot off the accelerator
    can easily stop them. (If it is very slippery, push the clutch in. Otherwise, the engine can keep the wheels
    from rolling freely and regaining traction.)
• Rear wheel braking skids occur when the rear drive wheels lock. Because locked wheels have less traction
    than rolling wheels, the rear wheels usually slide sideways in an attempt to "catch up" with the front wheels.
    In a straight truck, the vehicle will slide sideways in a "spin out." With vehicles towing trailers, a drive-wheel
    skid can let the trailer push the towing vehicle sideways, causing a sudden jackknife.

Correcting a Drive-wheel Braking Skid
• Do the following to correct a drive-wheel braking skid.
• Stop Braking. This will let the rear wheels roll again, and keep the rear wheels from sliding any
• Countersteer. As a vehicle turns back on course, it has a tendency to keep on turning. Unless you turn the
    steering wheel quickly the other way, you may find yourself skidding in the opposite direction.
• Learning to stay off the brake, turn the steering wheel quickly, push in the clutch, and countersteer in a skid
    takes a lot of practice. The best place to get this practice is on a large driving range or "skid pad."

Front-wheel Skids
• Driving too fast for conditions causes most front-wheel skids. Other causes include lack of tread on the front
    tires and cargo loaded so not enough weight is on the front axle. In a front-wheel skid, the front end tends to
    go in a straight line regardless of how much you turn the steering wheel. On a very slippery surface, you may
    not be able to steer around a curve or turn.
• When a front-wheel skid occurs, the only way to stop the skid is to let the vehicle slow down. Stop turning
    and/or braking so hard. Slow down as quickly as possible without skidding.
       Crossing Intersections
– Assume cross traffic may not obey control signs or
– Allow enough time for your entire vehicle and
  trailer to clear the road
– Approaching drivers may not realize you have a
  trailer attached
– Keep side lights and reflectors clean
              Making Turns
– Turns are more
  difficult due to vehicle
– Move to right lane
  and signal
– Wait for vehicles
  in other lanes
– Avoid improper
    Crossing Railroad Tracks
– Stop 15 to 50 feet of,
  and not closer than
  15 feet to, the tracks
– Stop and look
  both ways
– Do not shift gears
  when crossing tracks
– Make sure no one is
  passing you
– Signal intention to
– Watch driver you are
– Watch for vehicles
  entering road
– Watch approaching
– Do not get into a race
– Expect the unexpected
– Pedestrians have
  difficulty judging vehicle
– Pedestrians assume you
  see them
– Make sure they give you
– Prevent improper trailer
– Scan blind spots
          Reduced Traction
– Increase your
  following distance
– Slow down
– Apply brakes gently
  and steer smoothly
– Brakes are more likely
  to lock up when
  lightly loaded
– Slide sideways on
  banked curves
         Reduced Visibility
– Slow down
– Watch for stalled or
  slow-moving vehicles
  in front of you
– Turn on fog lamps or
  emergency flashers
– Keep lights and
  windshield clean
– Get off the road
  and wait
            True or False?

1. Once cargo is properly distributed and
   secured, you should not check it because
   it may then become unsecured.

 Cargo must be checked within first 50 miles.

2. Before startup or backup, you should walk
   around your vehicle to check for hazards.
         True or False? (cont.)

3. The most important rule in lane usage is
   to maintain a safe following distance.

4. You should stop between 5 and 15 feet of
   railroad tracks.

 Stop 15 to 50 feet before tracks.

5. The gear you use for descending a grade
   should be no higher than that required for
   ascending the same grade.

              Work Zone Safety
• Work Zone Facts at a Glance
   – Drivers not paying attention is the biggest cause of work zone
   – Speeding is the next biggest problem.
   – Over 40 % of work zone crashes happen in the transition zone
     before the work area.
   – Road construction is the most dangerous occupation in the
     United States.
   – More drivers and their passengers than workers die each year in
     work zones.
   – Work zone crashes tend to be more severe than other types of

Farm Equipment – Rural Roads

• What Can We Do?
  – Be Patient – the Farmer will pull off as soon as he has a safe
    place; however, shoulders may be soft, wet or steep and
    cause the farm vehicle to tip.
  – Yield to wide vehicles. If approaching a wide piece of
    equipment traveling in the opposite direction, stop, pull over
    and let them pass you.
  – Pass with caution – do not pass unless you can see clearly
    ahead of you and the vehicle you will pass.
  – Check the operator’s hand signals – do not assume they are
    letting you pass. They may need to swing wide to turn.
         Deer, Elk, Wild Animals

• Usually early morning and evening
• Unpredictable
• Herd Animals – where there is one, there may
  be more
• Can do significant damage to your vehicle
           What can we do?
  SLOW! Stay Alert! Look for More!
Commercial Vehicles
   Commercial Vehicles – No Zone
• The No Zone is the area around a truck where cars disappear
  into the blind-spots or are so close they restrict the driver’s
  ability to stop or maneuver safely.
• Position yourself so that you can see the face of the driver in
  their mirror.
