Can I queue in the Thai national express lane without my spouse if I have a Non-O visa based on marriage?

The discussion centers on whether a person holding a Non-O visa based on marriage can use the Thai national express lane when entering Thailand alone, without their spouse. While some users report they can use the Thai lane if they speak Thai or are traveling with children, others caution that they may be directed to the foreigner line. Overall, the experience seems to vary by individual circumstances.
