Headed to driving school next week. My sup says I must finish the Diad training on computer and pass with 90% to obtain the certificate and take it to school with me. Anyone know if this is true? I've been cramming the diad training for 2 days and having alot of trouble. My inst. sheet from HR says I gotta have CDL, DOT card, Browns, and know the 10 and 5. but doesn't mention diad. Any other tips or suggestions as to what to expect at school appreciated!!!!!
