During gameplay press

to open up the "Company Menu".
From here, go to "Jobs", then to "Tutorials". In here you will find multiple tutorials to complete, however, for this achievement we just want to abort one.
Load up the first available tutorial - either "Repair Vehicles" or "Flatbed CT660". Make sure to click

to start the tutorial. Once you have control again, simply press

, go to "Jobs", then "Tutorials". This will take you to the information regarding the tutorial you have started. Simply use

(down on the D-pad) to scroll to the "Abort Job" section.
Click

to abort, then

again to confirm your choice. Wait for the loading screen to finish and the "Job Aborted" summary to pop-up; then your achievement should pop around the same time.
Any improvements, leave a comment and I will do my best to make the solution better. Happy Hunting!
