CDL Tanker Practice Test Guide

CDL - Tanker Practice Test 1. An emergency forces you to stop your tanker quickly use controlled or or crash. You should stab braking 1. lock the brakes with the pedal and hold it there 2. use only the emergency brakes 3. use controlled or stab braking 2. A smooth bore tank is also know as: 1. a tank made of aluminum 2. an un-baffled liquid tanker 3. a liquid tank with baffles an un-baffled liquid tanker 3. Side-to-side surge can cause 1. a rollover 2. suspension system failure 3. overspeeding a rollover 4. Hauling liquids in tankers requires special care for the both the above following reason(s) 1. high center of gravity 2. liquid movement 3. Both the above 5. How does liquid surge affect the handling of a tanker? 1. surge can move the truck in the direction the liquid waves move 2. surge increases the wind drag of the truck 3. surge lets you turn corners tighter surge can move the truck in the direction the liquid waves move 6. A baffled tanker is one with 1. separate tanks inside the trailer 2. hollow balls floating in the liquid to slow movement 3. bulkheads in them with holes that let the liquid flow through bulkheads in them with holes that let the liquid flow through 7. Outage means 1. liquid weight 2. allowance for expansion of liquid 3. how fast the liquid tanks drain allowance for expansion of liquid 8. bulkheads 1/4 liquid-tight separators between compartments inside tanks are called 1. baffles 2. bulkheads 3. barriers 9. 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 steer 2. liquid surge will pull the tank from the truck 3. the truck will roll over you will continue in a straight line and keep moving forward no matter how you steer 10. You should know the outage needed for the liquids you carry because 1. Some of the heaviest liquids do not need any outage 2. 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 11. The movement of the liquid in partially filled tanks is surging called 1. waves 2. surging 3. splashing 12. Which of these statements about tankers and their both the above center of gravity is true? 1. Tankers can turn over at the speed limits posted for curves 2. Much of the loads weight is carried high up off the road 3. both the above 13. A tank endorsement is required for certain vehicles that transport 1. passengers 2. liquids and gases 3. hazardous materials 2/4 liquids and gases 14. Which of these statements about stopping and speed is true? 1. wet roads can double the stopping distance at any speed 2. you need about twice as much stopping distance at 40 mph as at 20 mph 3. both the above wet roads can double the stopping distance at any speed 15. The liquid in a tank with baffles can still have what kind of surge? 1. top-to-bottom 2.front to back 3. side-to-side side-to-side 16. 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 twice 2. brake slightly 3. speed up slightly speed up slightly 17. Separators with openings or holes in them, that are between compartments in a tank are called 1. bulkheads 2. baffles 3. barriers baffles 18. The amount of liquid to load into a tank depends on both the above what? 1. the legal weight limits 2. the amount the liquid will expand in transit 3. both the above 19. When your cargo tank has baffles, what handling effect do you expect? 1. The surge will be slower than in a tank without baffles 2. there will be less side-to-side surge than in a tank without baffles 3/4 there will be less front-to-back surge than in a tank without baffles 3. there will be less front-to-back surge than in a tank without baffles 20. When you load the small tanks of a cargo tank equipped with bulkheads, you should check the 1. distribution of weight 2. water content 3. air-to-fuel ratio distribution on weight 21. You are driving on a clear night. You must dim your The distance you headlights from high to low. You should adjust your can see ahead speed so you can stop within 1. the distance you will travel in the next 15 seconds 2. the distance you can see ahead 3. the length of your vehicle 22. Empty trucks 1. stop quicker when you use only the emergency or parking brakes 2. have better traction when stopping than full trucks 3. may require a longer stopping distance than full trucks 4/4 may require a longer stopping distance than full trucks
