As a commercial driver in Oklahoma, it’s important to understand what constitutes a major violation. These are the violations that could lead to the loss of your commercial driving privileges for up to one year, and they include driving or being in actual physical possession of a commercial vehicle with a blood alcohol level of.04 or more, refusal to submit to a chemical test, hit and run accidents, and any felony involving the use of a commercial vehicle. Additionally, a second conviction for any of these offenses results in a lifetime disqualification. If you’re facing a major violation or serious traffic offense, it’s crucial to speak with an experienced attorney.
