• To prevent over-width trucks from becoming a hazard on narrow bridges
• To prevent the maximum tire load rating from being exceeded by narrow axle spacing

When is the braking effect of the engine at its greatest?

• When it is near the governed RPMs and the transmission is in the lower gears.

What happens if your ABS light stays on indicating that your ABS has malfunctioned?

• Get stopped immediately. Do not drive the vehicle. Call a repair service or tow truck.
• You still have regular brakes. Drive normally, but get the system serviced soon.
• You will actually have more braking power than normal but it will be hard to control and could easily lock up the brakes, even under normal application pressure. Do not drive the vehicle.
• You will still have some brakes, but they will have considerably less stopping power. Do not drive until it is fixed.

If you slide the 5th wheel toward the nose of the tractor, what will be the effect?

• You will increase the weight on the steer axle and increase the weight on the drive axles
• You will decrease the weight on the steer axle and it will have no effect on the drive axles
• You will decrease the weight on the steer axle and take weight off the drive axles
• You will increase the weight on the steer axle and take weight off the drive axles

When the emergency line loses pressure, it causes the trailer emergency brakes to come on. What else happens?

• The trailer parking valve will close (the air supply knob will pop out)
• The tractor service brake will be applied
• The emergency air chambers will pressurize
• The tractor parking valve will close (the air supply knob will pop out)

Define "Total Stopping 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 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 your vehicle will travel in ideal conditions, while you are braking.
• The distance your vehicle travels, in ideal conditions, from the time your eyes see a hazard until your brain recognizes it.
