CDL Questions and Answers

When is a trailer most likely to jackknife?

The answer to this question is C. A jackknife is a type of knife that can be folded easily. If you would jackknife your trailer, you have to make sure that it is empty. Otherwise, you will spill all of its contents all over the road. The container may also be too heavy to undergo this process if it would come with items. This is a process that can be done to make the vehicle face forward again. This is usually used when the vehicle skids, and it needs to face ahead so that it will work still. What are the possible reasons why a vehicle may skid? One of the most common causes is driving through icy roads that cannot be avoided at times.

What should you ensure if the front trailer supports are up and the trailer is resting on the tractor?

Once the trailer supports are up and the tractor is on, you must make sure there is space between the landing gear and the tractor frame. Having enough clearance between the landing gear and the frame will ensure that nothing gets stuck. If grass or something gets stuck up in there, there is a good chance the blades will catch. When blades catch, it could mean trouble. If a blade catches, and it catches on the landing gear or the frame, it could spark. If it sparks on the field, that could mean a fire. Having enough clearance is crucial to making sure the tractor runs smoothly. Otherwise, you won’t be able to use it properly and that makes the work unsafe for everyone.
