I was failed by my UPS driving instructor when he was giving me conflicting instructions it seemed like on purpose as he stated, he like to throw a lot of different things at drivers to see if they can handle it.the things that i was failed for were very unclear and i pulled behind a car at the stop light with at least a car length and a half of space,i was told for the first time that i should leave more space,not a specific distance so i followed these instruction but maybe not to the exact specifications because how would i be able to make this judgement when driving a truck of this size for the first time.then he took away points from my backing of the truck, he did not give me clear instructions of which bay-door to back the truck into as your will see in his statement.but i still executed the back-in flawlessly but i forgot to use the horn. Then took points away because he said i didn't effectively scan the crosswalk and intersection when i did but how can he see what i see.please some one look over the attachments and let me know what you think
