Ignorant embarrassed or what?

Please continue to be a gentleman. As someone about to start class 1 training, I’m dreading the first weeks on the road after passing and finding gainful class 1 employment.
Reversing is my biggest fear. Hoping to come across plenty of helpful drivers in that time to guide me through it.
Good manners cost nothing as my parents used to say, you can be sure I’ll say thank you for all help received.
