What should be ensured about the axles during the inspection?

Answer: A — The axles must be secured

During the inspection, it is essential to ensure that the axles are secured. This is a critical safety aspect because properly secured axles are necessary for the stability and structural integrity of the vehicle. If the axles are not secured, they could lead to severe consequences while driving, including loss of control of the vehicle, which can result in accidents and endanger both the driver and others on the road. While assessing the axles, it is also important to check for other conditions, such as visible leaks and any cracks. However, the securing of the axles is the primary concern as it directly relates to the safe operation of the vehicle. It's vital to perform a thorough inspection of both sides of the axles to ensure they are equally secure and in good condition, as neglecting any part can compromise vehicle safety.
