CDL Vehicle Combination Practice Test

When inspecting the landing gear after uncoupling the trailer, the tractor should be completely cleared from the trailer. This positioning ensures that the driver can safely inspect the landing gear without the risk of the tractor inadvertently coming into contact with the trailer. By being completely separated from the trailer, the driver can move freely around the landing gear, checking for any potential issues, without the concern of the tractor obstructing the area or complicating the inspection process.

Being next to the trailer or close to the rear does not provide the same level of safety, as the driver would still be at risk of accidental contact with the trailer during the inspection. Positioning the tractor in front of the trailer also poses potential hazards, such as the risk of not seeing if the landing gear is functioning properly during the inspection. Hence, completely clearing the tractor from the trailer provides the best safety and visibility for an effective inspection.
