What are two problems especially important to tanker operation? A high center of gravity and the liquid surge of the cargo transported A low center of gravity and leakage from tanks The tendency of milk to spoil and driver inability to see into the tank.

What is a tank compartment? Make money smithing mithril tank for storing hoses and couplings A liquid-tight division of a tank A wall with many openings. How forex factory expert advisor a bulkhead different from a baffle? Bulkheads are larger than baffles.

Bulkheads are liquid-tight and baffles have holes in them The brakes will work better. The failure of molasses to flow properly in cold weather The height of the tractor The weight of the liquid. One of these helps determine the euro exchange in ghana of liquid you can load in a tank The legal weight and load limits of your vehicle The wheelbase between your front and second axles The number of pumps that can be used to load your tank.

The size of the opening in the dome lid The amount that the liquid might expand in transit The maximum speed at which you will be driving. Liquid has more room to move in a partially-filled tank. The air pressure is greater inside a partially-filled tank. Many semi trailer tanks are slanted so that the lower end is at the back. Cargo Test B 1: The side-to-side surge of liquid in a tank can cause a vehicle to? Stop instantly Bend at the fifth wheel connection Roll over. Yes, all limits are set with tankers in mind No, tankers are exempt.

No, except that smooth bore tanks usually transport food products. Yes, forward and back surge is strong in smooth bore tankers. No, but tanks with bulkheads or baffles are harder to keep clean.

Baffles offer little resistance to? Front-to-back surge Back-to-front surge Side-to-side surge. In what direction does liquid surge cause a vehicle to move? Forward and much faster Backward and much slower It will tend to move the vehicle in the direction that the liquid moves.

Will have less front-to-back surge Will have less side-to-side surge There will be no difference. Why are unbaffled tanks used to transport food products? Sanitation regulations often forbid the use of baffles. Food products are lighter than gasoline and require less support. The baffles cause syrups to congeal. The amount that a liquid can expand in transit can be affected by?

The grade that is being pulled The suddenness with which the brakes are applied Air pressure is converted into hydraulic pressure.

What is a reason for filling a tank only partially? The shipper ordered a small quantity. The shipment was too light in weight. The tank had a hole that leaked liquid.

Liquid surge will tend to shove the vehicle ahead. A vehicle on a slippery surface can become stuck more easily. The wave of the liquid inside the tank may hit the rear of the tank. Cargo Test C 1: What is overturn protection? Guards to protect fittings and valves in case of a rollover Weight reducers that will cause the trailer to ride lower Guards that keep a tractor from turning too sharply and breaking air lines.

The size of the hose connections The size of the bulkheads Weight distribution of the commodity being loaded. What is a dome cover? A cover to protect an opening where a tank is filled A cover to protect a drain on the bottom of the tank An extra cover to protect the cab in case of a rollover.

When the sound of your engine tells you it is time to shift gears When your tachometer shows RPM or higher Do not shift gears when crossing over railroad tracks. After you have completed unloading, but before you drive away Before you start to unload or during the unloading After the tank has been cleaned or another commodity has been loaded.

What can liquid surge do to the handling of a tank vehicle? Surge improves your ability to turn corners tighter. Surge may move the vehicle in the direction the liquid moves in the tank. Surge causes tank contamination. A vehicle with empty tanks may? Be stopped more quickly with the emergency brakes Require a greater stopping distance than a loaded tanker Have better traction at all times than does a loaded tanker.

Which is true about the emergency steering of tankers? Do not apply the brakes when making a quick turn. Countersteering is easy with a loaded tanker. Never try to stop a tanker without turning. You do not want to put too much weight on the front or on the rear. Computers will not check this for you. Tanks can not be bent or strained. Combination Test A 1: To prevent rollovers, remember to: Keep the load centered Keep the load as low as possible Go slow around turns All of the above.

Large combination vehicles take longer to stop: When they are empty When they are loaded Than bobtail tractors It takes the same time whether empty or loaded. When traveling under 40 mph, you should follow other vehicles: Only during the day With a distance of one second for every ten feet of your vehicle length With a distance of one second for every twenty feet of your vehicle length As close as possible so others don't cut in. The earliest way to notice a trailer skid is: By feeling the pull on your steering wheel By feeling a jerking in the back of the tractor By seeing it in your mirrors By hearing the squeal from the tires.

If you start a trailer skid you should: Step on the brakes quickly Release the brakes to get traction back Use the trailer hand brake Slowly apply pressure to the brakes. Offtracking" occurs when you go around a corner and: The rear wheels follow a different path than the front wheels The rear trailer goes off the road The rear wheels follow the front ones in a straight line The front of the trailer pulls to the right.

The trailer hand valve should be used: Which one of the following statements about tractor protection valves is NOT true?: It keeps air in the tractor in the event the trailer air leaks It is controlled by the trailer air supply valve in the cab When it closes it allows air to leak from the tractor line It will close automatically if air pressure is low.

The trailer air supply control: Is a red, triangular-shaped knob Is a yellow, square knob Is a red, square knob Is a red, eight sided knob. Which one of the following is controlled by the foot brake?

The service air line The emergency air line The shut off valve The hose coupler. Combination Test B 1: Before driving away, how can you always test the trailer brakes?

With the hand valve or by pulling the tractor protection valve and then pulling against the brakes in a low gear. With the hand valve or by pulling the tractor protection valve, and accelerating. With the hand valve or by pulling the tractor protection valve, and pulling against the brakes gently at a maximum speed.

How are the air tanks on trailers and converter dollies filled? By the tractor protection valve. By the air compressor cut off valve. By the emergency supply line from the tractor. The position of the foot pedal. The position of the brake linings. The pressure in the service line. They should be in the open position except at the back of the last trailer. The should be in the open position. They should be in the closed position.

Use wheel chocks Use available rocks. You may not notice anything until you try to put the brakes on when air loss from the leak will quickly lower the air tank pressure Nothing will happen.

You will hear a loud explosion. Why must the fifth wheel plate have enough grease? To prevent sparks - and smoke. To prevent steering problems. Slightly to the left of the trailer. Slightly to the left of the center of the trailer. Directly in front of the trailer. Four feet eight inches. Well above the top of the fifth wheel. Just below the middle of the fifth wheel. Check the light connections. Supply air to the trailer electrical system. Supply air to the trailer system.

Combination Test C 1: Describe what the service line is for: To carry air to the parking brake to control the trailer brakes. To carry air to a relay valve that allows the trailer brakes to be applied quickly. To carry air to the cab of the rig to cool it. What are other names for the Service Air Line? Control line or signal line Straight line or control line Curved line or signal line. What is the emergency air line?

Air lines connecting the parking brake to the trailer brakes. Air lines that control the emergency brakes of the tractor. Air lines that control the emergency brakes on combination vehicles. What is the emergency air line for? To engage the front brakes of the tractor in case of an emergency.

To engage the trailer brakes in case of air pressure loss. To have extra air pressure in case you need it. Because you don't want the trailer rolling down a hill. Because if the air pressure leaks away or down, there will be no brakes. Because some states require checking of trailer wheels.

Should you do a walk around inspection when preparing to pull Doubles or Triples Yes No. Combination Test D 1: Trucks turn over easier when fully loaded and are: Easy to get turned back right. Five times more likely to roll over in a crash than empty rigs.

Ten times more likely to roll over in a crash than empty rigs. The following two things will help prevent rollovers. Keep the cargo close to the front and drive slowly around turns. Keep the cargo as close to the ground as possible and drive slowly around turns.

Keep the cargo to the back of the rig and drive the speed limit. The rear trailer is twice as likely to turn over as the tractor. The front trailer is twice as likely to turn over as the tractor. Each trailer is equally likely to turn over as is the tractor. Because the brake handle is too hard to reach. Because the brakes on the trailer wheels cause the skid in the first place. Because the brakes on the trailer wheels will not respond to the hand brake.

What is off tracking? When a vehicle goes around a corner, the rear wheels follow a different path than the front wheels When a vehicle goes around a corner, and the driver pulls off the road. When a vehicle goes around a curve and turns back the other way. What is a "trailer jacknife? When the wheels of a trailer lock up and the trailer swings around.

Reduce the risk of water in the air brake valves in warm weather When the wheels of a trailer lock up and the trailer pulls the tractor to a stop. Why should you not use the trailer hand valve while driving? Because it won't work as well as the foot brake. Because you should use the parking brake. Because of the danger of making the trailer skid. Describe what the trailer air supply control does. It is used to supply the trailer with air, shut the air off and put on the trailer emergency brakes.

It is a yellow, six sided knob used to control the tractor protection valve. It is a device used to keep the trailer behind the tractor. Combination Test E 1: Space enough to allow air to flow freely. By tapping it with a rubber hammer.

By pulling the tractor ahead gently with the trailer brakes locked. By pulling it by hand. The shank of the kingpin. Over the locking lever. Level with the locking lever. Under the locking lever. Raised at least six inches above the ground. Raised at least one foot above the ground with the crank handle secured in its bracket. Fully raised with the crank handle secured in its bracket. Between the fifth wheel and the floor of the trailer. Between the tractor taillights and the landing gear. Between the tops of the tractor tires and the nose of the trailer.

It should always be behind the lighter trailer. It should always be in front of the lighter trailer It should be placed where it will have the least wind resistance. Five feet eight inches. It must be slightly lower than the center of the fifth wheel. The dolly tow bar may fly up. There may not be enough grease on the pintle hook to enable it to ride smoothly. It may be too hard to unlock it next time.

Combination Test F 1: There is no difference as to the load so far as rolling over is concerned Fully loaded rigs are less likely to roll over in a crash. Fully loaded rigs are 10 times more likely to roll over in a crash. What two things can a driver do to prevent rollovers? Keep the cargo as close to the ground as possible. Go slowly around turns. Try to raise the center of gravity of your load.

The worm effect The hula effect. At least one second for each unit of your vehicle plus another second if going over 45 miles per hour. At least one second for each 20 feet of your vehicle length, plus another second if going over 35 miles per hour.

At least one second for each ten feet of your vehicle length, plus another second if going over 40 miles per hour. Use your highbeam headlights at all times. Look far ahead all the time. Slow down to a safe speed before going into a turn. Focus your attention on the taillights of the vehicle ahead.

Look far enough down the road and allow lots of following distance. When lightly loaded, stiff suspension springs and strong brakes give poor traction and make it easy to lock up the wheels. Combination vehicles are longer than bobtails and therefore require more length to stop. Empty trucks are harder to control and the brake connections are more likely to come loose.

Why must you be extra careful when bobtailing? Bobtails may not be equipped with splash guards or back bumpers.

Bobtails stop more smoothly but take longer to stop. Bobtails can be hard to stop smoothly and take longer to stop than a loaded tractor-semi trailer. The trailer will immediately stop.

The trailer will tend to jackknife or swing around. The trailer will automatically break loose from the fifth wheel assembly. This is the best way to recognize if the trailer has started to skid. To tell if the mirrors are still in adjustment. To tell if your cargo door comes open. Combination Test G 1: The service air line is controlled by: The pressure applied to the line by the foot brake or the trailer hand brake The relay valve which connects the trailer air tanks to the trailer air brakes The relay valve which sends air pressure from the trailer air tank to the trailer brake chambers All of the above.

A device which connects the service and emergency air lines from the truck to the trailer is called: Relay switch Glad hands Service couplers Shut off valves. When coupling the glad hands, you should NOT do the following: Clean the couplers before a connection is made Press the two seals together at a 90 degree angle Cross air supply lines to test them for leaks Match the colors to each other, or read the tags before connecting.

If you cross connect the two air lines the following will result: Nothing, the lines are interchangeable You will not have air going to the trailer brakes Your tractor brakes will lock up You could not move the tractor. The fifth wheel should be checked to see if: There is damage or missing parts It is properly greased The jaws are open All of the above. When coupling the trailer, back up slowly until: The load shifts inside the trailer The fifth wheel just touches the trailer You can see the rear wheels in the mirror You hit the front of the trailer with the tractor.

In order to supply air to the trailer, you must first: Push in the tractor protection valve. Pull out the "air supply' knob Stop engine so you can hear the brakes Cross the air lines to check for leaks. A king pin is: The pin which locks the air brake lines together A pin which locks the trailer to the tractor on the fifth wheel A pin which holds the wheels on the axles The pin a driver receives for safe driving.

In order to inspect the coupling you should: Make sure there is space between the upper and lower fifth wheel Check that the locking lever is in the open position Make sure the fifth wheel jaws are open Use a flashlight if necessary. You should crank the landing gear until: It is six inches off the ground You can clear railroad tracks The crank handle is loose It is as far up as it will go.

Sample Test A Sample Test B Sample Test C Sample Test D Sample Test E Sample Test F Sample Test G Sample Test A 1: Don't use the trailer handbrake. Press harder on the brake pedal to stop the vehicle faster Set the trailer handbrake.

They are longer and they cannot be turned or stopped suddenly They are longer and weave from side to side They are longer and are taller than tractors. Move quickly because you have a deadline Because of the large size of your vehicle expect others to see you and make room for you Make sure there are large enough gaps before entering or crossing traffic. Your drive wheels provide security for the pulling unit only Your front wheels may not be equipped with brakes You have more length and more dead axles to pull.

When the emergency brake is not working Never. Always When the brake pedal does not work. The one-way check valve The relay valve The tractor protection valve.

The trailer handbrake The trailer emergency brakes The brakes on the front axle. Push it in to supply the trailer with air. Pull it out to release all air to the trailer Pull it out to release all air to the trailer. Do not push it in when the vehicle is underway Push it in to supply the trailer with air.

Pull it out to shut the air off and put on the trailer emergency brakes. The normal position is used for pulling a trailer. The emergency position is used to shut air off to the trailer The normal position is horizontal. The emergency position is vertical The normal position is used for supplying air to the drive wheel brakes.

The emergency position is used to substitute for the emergency brakes. Which valves on the service line on the trailer connect the trailer air tanks to the trailer air brakes One-way check valves Relay valves Automatic valves. What is one purpose of the emergency air line?

It allows you to continue your trip when the primary system is malfunctioning It activates an emergency locator transmitter It supplies air to the trailer air tanks. The emergency trailer brakes will fail The emergency trailer brakes will fade The emergency trailer brakes will come on. The valve will open The valve will close The valve will pop out.

If the air lines on a truck are color coded, which lines are blue? The emergency lines The spring line. A 45 degree angle A 90 degree angle A degree angle.

To keep the brakes from overheating To keep dirt and water out the lines. Unhook the air line connections Check the air line connections Tighten the air line connections. Do trailers made before have spring brakes? Most of them do. All of them do. Is it important to be careful when driving doubles and triples?

Special care should be taken when pulling two or three trailers because more things can go wrong and are less stable than other commercial vehicles TRUE FALSE. Doubles and triples are not as likely to turn over as are other combination vehicles TRUE FALSE. The lighter load in first position, the heavier in the rear The heavier load in first position, the lighter in the rear.

It does not matter which trailer is heavier You should equalize the load. What is a converter dolly used for? To couple tow or three trailers behind a tractor truck. To help move cargo in a semi-trailer To couple a trailer to a tractor. None of the above. Do all converter dollies have spring brakes? Release dolly brake by opening the air tank petcock or if the dolly has spring brake, use the dolly parking brake control.

Wheel the dolly into position by hand so it is in line with the kingpin. Use the tractor and first semi trailer to pick up the converter dolly and move it into position All of the above. The dolly tow bar may fly up if you unlock the pintle hook with the converter dolly still under the rear trailer TRUE FALSE. Coupling and uncoupling methods are the same for more common tractor-trailer combinations, but there are other ways of coupling and uncoupling the many types of truck-trailer combinations that are in use TRUE FALSE.

There are more things to inspect on a combination vehicle than on a single vehicle TRUE FALSE. To test the trailer service brakes you should: Lightly test brakes at 5 mph Apply hand control and check to see if you feel the trailer brakes come on Depress the brake pedal. When pulling triple trailers, which unit is more likely to roll over: The front trailer The middle trailer The last trailer The tractor.
