2020 Q1 Safety Quiz Question Title OK Question Title OK Question Title * 1. Why is it so important to perform a thorough pre and post-trip inspection??? The driver can find the issues, defects, problems and have them repaired before the Commercial Enforcement officer does.

While checking my wheels, a driver should look for… The dirt and grime that is on the wheels during the winter months driving can hide issues if I am not looking for them, and paying attention A puddle of oil sitting in the bottom of the wheel no matter how small is likely an indicator that a seal within the axle has failed and I need to call the shop, because I am out of service. If this is what I find on a trailer during a post-trip inspection, it is my responsibility to call the shop and let them know the location of the trailer and per their instruction, place the vehicle OOS (out of service) so repairs can be made not interrupting another drivers plan.
