4. What does trailer tongue load contribute to on the tow vehicle?

A. Wheel diameterB. Payload and axle loadingC. Fuel tank capacityD. Battery voltage

5. How should you choose the hitch-ball diameter?

A. Match the coupler's specified sizeB. Choose the closest-looking sizeC. Always use the largest ballD. Match the tire rim diameter

6. What should you verify after closing the trailer coupler?

A. Only that its paint matchesB. Only that the jack is downC. Only that the latch can move freelyD. It is fully seated, locked and secured as specified

7. Why use required safety chains or cables?

A. Carry all normal tongue weightB. Eliminate the need for trailer brakesC. Provide a secondary connection if the hitch separatesD. Replace the coupler latch

8. What should you check about safety-chain length and routing?

A. They prevent any trailer articulationB. Enough turning clearance without dragging, following the manualC. They drag to mark the roadD. They are tied to the brake hose

12. What is the purpose of a trailer brake controller where required?

A. Charge every trailer appliance automaticallyB. Control compatible trailer brake applicationC. Increase tire diameterD. Set engine valve clearance

13. How should cargo be secured?

A. With suitable rated restraints and correct anchor pointsB. By relying only on its weightC. With loose clothing strapsD. By placing a tarp without restraints

14. When should restraints and connections be rechecked?

A. Only after cargo falls offB. Only when paint wearsC. Never after leaving homeD. At safe stops and as the manuals recommend

15. Why allow extra following distance when towing?

A. The hitch controls trafficB. Trailer tires prevent skidsC. The combination needs more room to react and stopD. The trailer always doubles traction

16. Why do trailer wheels often need extra clearance in a turn?

A. They automatically match the front wheelsB. They may track inside the tow vehicle's pathC. They always track outside every curveD. They cannot turn at all

17. Why practice backing in a clear area first?

A. Trailer response differs from the tow vehicle's responseB. It changes the trailer's weight ratingC. It removes the need for mirrorsD. It guarantees no future mistakes

18. What should you inspect on trailer tires?

A. Only sidewall lettering styleB. Only valve-cap colorC. Only the tread's appearance from afarD. Pressure, condition and load suitability

19. Why use wheel chocks when preparing to unhitch on a suitable surface?

A. Replace every parking supportB. Reduce electrical currentC. Help prevent trailer movementD. Increase hitch-ball capacity

20. What is the best way to know actual loaded trailer weight?

A. Count wheel studsB. Use an appropriate scaleC. Estimate from empty dimensions onlyD. Use the hitch color
