When a vehicle goes around a corner, the rear wheels follow a different path than the front wheels. This is called:

• Rolling over
• Turn scraping
• Off-tracking
• Inner-tracking

When a vehicle goes around a corner, the rear wheels follow a different path than the front wheels. This is called off-tracking or "cheating."

A stack of shortwood loaded lengthwise can be secured with one tiedown if:

• They are blocked in the front by a headboard or another stack of logs.
• All of these apply.
• They are blocked in the back by the vehicle's end structure or another stack of logs.
• All logs in the stack are less than 10 ft long.

Driving too fast for conditions causes most front-wheel skids. Other causes include:

• ABS system engaged on the front wheels or hydraulic brakes
• The trailer brake is not fully released or the Jake Brake setting is too high
• Lack of tread on the front tires and cargo loaded so not enough weight is on the front axle.
• A misaligned brake chamber or too much speed in the curve

You receive a scale ticket and your drive axles are 35,700 and your trailer tandems are 30,600. Based upon a trailer with 4 inch slider rail hole spacings, what is the minimum number of holes you would have to slide the tandems to get the weight legal, and what would the final weights be?

• Slide tandems forward 6 holes - 33,750 drive axles - 32,550 trailer tandems
• Slide tandems forward 7 holes - 33,950 drive axles - 32,350 trailer tandems
• Slide tandems back 6 holes - 33,950 drive axles - 32,350 trailer tandems
• Slide tandems back 7 holes - 33,750 drive axles - 32,550 trailer tandems

The two main hole spacings you'll find are 4 inches and 6 inches. You can estimate that you will move 250 pounds per hole for 4 inch spacing, and 400 pounds per hole for 6 inch spacing.

Define "Reaction Distance":

• The distance your vehicle will travel in ideal conditions, while you are braking.
• The total minimum distance your vehicle has traveled, in ideal conditions, with everything considered, until you can bring your vehicle to a complete stop.
• The distance you will continue to travel, in ideal conditions; before you physically hit the brakes in response to a hazard seen ahead
• The distance your vehicle travels, in ideal conditions, from the time your eyes see a hazard until your brain recognizes it.

Reaction Distance. The distance you will continue to travel, in ideal conditions; before you physically hit the brakes in response to a hazard seen ahead. The average driver has a reaction time of three-fourths second to one second. At 55 mph this accounts for 61 feet traveled.

Memorize this definition. You may see it on the test and you need to understand it.

You may or may not be able to stop faster with ABS, but you should be able to:

• Steer around an obstacle while braking and avoid skids caused by over-braking.
• Lock up the wheels, which creates more traction on the roadway
• Keep the steer tires from veering too hard and thus avoiding a rollover
• Keep the air brake fluid primed for maximum braking force

Option #3 for securing metal coils transported with eyes lengthwise includes all of the following except:

• Attaching at least two tiedowns through the center of the coil.
• Attaching at least one tiedown over the top of the coil near the rear of the coil.
• Using blocking or friction mats to prevent forward movement.
