CDL - Tanker Practice Test Flashcards

CDL - Tanker Practice Test Flashcards Hauling liquids in tankers requires special care for the following reason(s)1. high center of gravity2. liquid movement3. Both the above both the above liquid-tight separators between compartments inside tanks are called1. baffles2. bulkheads3. barriers bulkheads How does liquid surge affect the handling of a tanker?1.surge can move the truck in the direction the liquid waves move2. surge increases the wind drag of the truck3. surge lets you turn corners tighter surge can move the truck in the direction the liquid waves move When your cargo tank has baffles, what handling effect do you expect?1. The surge will be slower than in a tank without baffles2. there will be less side-to-side surge than in a tank without baffles3. there will be less front-to-back surge than in a tank without baffles there will be less front-to-back surge than in a tank without baffles The amount of liquid to load into a tank depends on what?1. the legal weight limits2. the amount the liquid will expand in transit3. both the above both the above When you load the small tanks of a cargo tank equipped with bulkheads, you should check the1. distribution of weight2. water content3. air-to-fuel ratio distribution on weight Outage means1. liquid weight2. allowance for expansion of liquid3. how fast the liquid tanks drain allowance for expansion of liquid The best way to take a curve in a tanker is to slow to a safe speed before entering the curve and then _______ as you go through it.1. downshift twice2. brake slightly3. speed up slightly speed up slightly You are driving a tanker truck. The front wheels begin to skid. Which of these is most likely to occur?1. you will continue in a straight line and keep moving forward no matter how you steer2. liquid surge will pull the tank from the truck3. the truck will roll over you will continue in a straight line and keep moving forward no matter how you steer An emergency forces you to stop your tanker quickly or crash. You should1. lock the brakes with the pedal and hold it there2. use only the emergency brakes3. use controlled or stab braking use controlled or stab braking Side-to-side surge can cause1. a rollover2. suspension system failure3. overspeeding a rollover The liquid in a tank with baffles can still have what kind of surge?1. top-to-bottom2.front to back3. side-to-side side-to-side A tank endorsement is required for certain vehicles that transport1. passengers2. liquids and gases3. hazardous

materials liquids and gases

A baffled tanker is one with1. separate tanks inside the trailer2. hollow balls floating in the liquid to slow movement3. bulkheads in them with holes that let the liquid flow through bulkheads in them with holes that let the liquid flow through Empty trucks1. stop quicker when you use only the emergency or parking brakes2. have better traction when stopping than full trucks3. may require a longer stopping distance than full trucks may require a longer stopping distance than full trucks Separators with openings or holes in them, that are between compartments in a tank are called1. bulkheads2.baffles3. barriers baffles You are driving on a clear night. You must dim your headlights from high to low. You should adjust your speed so you can stop within1. the distance you will travel in the next 15 seconds2. the distance you can see ahead3. the length of your vehicle The distance you can see ahead Which of these statements about stopping and speed is true?1. wet roads can double the stopping distance at any speed2. you need about twice as much stopping distance at 40 mph as at 20 mph3. both the above wet roads can double the stopping distance at any speed

A smooth bore tank is also know as:1. a tank made of

aluminum2. an un-baffled liquid tanker3. a liquid tank with baffles an un-baffled liquid tanker You should know the outage needed for the liquids you carry because1. Some of the heaviest liquids do not need any outage2. some liquids expand more than others when they get warm .3. tank baffles are not always legal with outage some liquids expand more than other when they get warm Which of these statements about tankers and their center of gravity is true?1. Tankers can turn over at the speed limits posted for curves2. Much of the loads weight is carried high up off the road3. both the above both the above The movement of the liquid in partially filled tanks is called1. waves2. surging3. splashing surging
