2. If stopped on a hill, how can you start moving without rolling back? Put on the parking brake whenever necessary to keep from rolling back. Release the parking brake only when you have applied enough engine power to keep from rolling back.

When should you downshift automatic transmissions?
When should you downshift automatic transmissions? You can select a low range to get greater engine braking when going down grades. The lower the ranges prevent the transmission from shifting up beyond the selected gear (unless the governor rom is exceeded).
What is the basic method for shifting up?
Basic Method for Shifting Up.
This is the basic method: Release accelerator, push in clutch and shift to neutral at the same time. Release clutch. Let engine and gears slow down to the rpm required for the next gear (this takes practice).
Why should you be in the proper gear before starting down a hill?
Why should you be in the proper gear before starting down a hill? So you only have to apply the brake just hard enough to feel a definite slowdown. So you don't have to shift gears going downhill. So you can go through the gears on the way down.
What two things are important to prevent rollovers?
The following two things will help you prevent rollover-- keep the cargo as close to the ground as possible and drive slowly around turns. Keeping cargo low is even more important in combination vehicles than in straight trucks. Also, keep the load centered on your rig.
What controls shifting in automatic transmissions?
Transmission Control Module (TCM) or Powertrain Control Module (PCM) All automatic transmissions use a control module to regulate speed, gear changes, and clutch engagement. ... It is responsible for timing shifts, shift feel, and engaging the clutch.
How do you move a car uphill?
When you are going uphill, slow down before the turn, shift down to a lower gear and accelerate through the turn. A very important point to remember here is that you need to be highly observant if any car is coming from above. For downhill, again slow down before the turn and take your foot off the accelerator.
What are the two ways to know when to shift?
There are two ways of knowing when to shift: Use engine speed (rpm). Study the driver's manual for your vehicle and learn the operating rpm range. Watch your tachometer, and shift up when your engine reaches the top of the range.
How should you know when to shift?
Generally, you should shift gears up when the tachometer is around “3” or 3,000 RPMs; shift down when the tachometer is around “1” or 1,000 RPMs. After some experience with driving a stick shift, you'll be able to figure out when to shift by the way your engine sounds and “feels.” More on that below.
Do empty trucks have the best braking?
Quote From The CDL Manual:
But the brakes, tires, springs and shock absorbers on heavy vehicles are designed to work best when the vehicle is fully loaded. Empty trucks require greater stopping distances, because an empty vehicle has less traction. It can bounce and lock up its wheels, giving much poorer braking.
What vehicles off track the most?
Longer vehicles will offtrack more. The rear wheels of the powered unit (truck or tractor) will offtrack some, and the rear wheels of the trailer will offtrack even more. If there is more than one trailer, the rear wheels of the last trailer will offtrack the most.
In which gear should you drive when going down a steep hill?
Downhill: Use first gear when driving downhill as a primary source for braking. Engine braking means you don't need to use the brake pedal as much, which keeps your wheels turning. If the wheels are turning you can steer, important when undertaking a steep downhill run.
When trying to prevent a rollover it is important that the driver not to?
What two things are important to prevent rollover? Keep the cargo close to the ground, and drive slowly around turns.
What is a good rule to follow when steering to avoid a crash?
Speed up as you get nearer to the hazard. When turning quickly to avoid colliding with a hazard in the roadway, you should always keep both hands on the steering wheel. You must have a firm grip on the wheel to be able to turn quickly.
What is the safest and easiest way to back up with a trailer?
look over your shoulder and look through the back window of your vehicle. Focus on the rear end of the trailer and maneuver it into the right place. Once again do not be afraid to go forward and move back in to correct your angle. Do not worry about who is watching, keep safety your priority, relax and reverse.
