One of the main reasons a driver cant always get what he wants is mainly dac and mvr sure some of these things are unavoidable but many of them are. If you are a new driver one of the biggest worst things you can do is abandon a truck,load or get fired.The thing with mvrs of course is just use common sense if the company is screaming get it there get it there just take your time and get there safely if they are wanting you to take a 1000 mile run in 8 hours then you dont need to be working for them in the first place.If you are wanting to make a career out of truck driving research the company you go with before you go to orientations......yes alot of companies count orientation as employment on dac....look at a companies stock price also are they falling going up ,etc. doing these things will always help and always remember to keep it safe...
