Getting a DWI in SD what happens to cdl license?

First, you'll lose your CDL. One year suspension is typical for a first offense. You'll be able to get your CDL reinstated - you may even be able to get a hearing to have it reinstated before the one year period is up.

For the next three years after your conviction, nobody is going to hire you as a driver, whether as a CDL driver or non-CDL driver. To be able to insure you, the premiums they paid for insurance would be astronomical. So they're not going to be willing to do that.

From four to five years after your DUI conviction, your chances of finding employment are barely better.

For six to seven years after your conviction, it will still be a major impediment to finding employment as a CDL driver.
