Can you get a Trucking job after DUI?

If your DUI conviction was within the last three years, then no. If it was more than three, but less than five years since your DUI conviction, it's possible but unlikely. If it was more than seven years ago, and there aren't multiple convictions to report, you're good to go - however, you won't be eligible to drive into Canada, where DUIs are a felony offence.
