No, it does not. Anything on your MVR prior to you getting a CDL will still be on your MVR after you get a CDL.
You get a copy of your MVR from your state DMV office.
Yes you can. ALL traffic tickets go on your MVR - there isn't a separate MVR for non-CMV tickets.
It stays on your MVR for seven years.
The CDL is federally administered. If you get a ticket while operating your personal vehicle in another state, it will still show on your MVR for your home state.
For insurance purposes, points acquired in the last three years are counted. As for your MVR, any convictions, violations, forfeitures, etc. remain on your MVR for seven years.
No. The only way to get such a report is to purchase a copy of your MVR from your state's DMV.
The drug screen is a mandatory part of your CDL physical. If you don't take it then, you don't pass your DOT physical, and you won't get a medical card - hence, you don't get your CDL. If you already have a CDL, and you refuse to take a pre-employment drug screen, you don't get hired. If you're already employed as a CDL driver, and you refuse a quarterly or other periodic drug screen, you lose your job, and a big black mark goes on your MVR. If you refuse a mandatory post-incident drug screen... well, welcome to the wonderful world of implied consent. You'll lose your job and your licence.
It'll remain on your MVR for seven years, as it does in all states.
Three years for insurance purposes, but convictions and forfeitures will show on your MVR for seven years.
For insurance purposes, three years. However, violations will show on your MVR for seven years.
The most simple way is to ask them if they'd show it to you. Otherwise, you put in a request for a copy of their MVR at the DMV office.
