What condition must be met for a driver's license issued by this state to remain valid for a person on active duty in the armed forces?

For a driver's license issued by the state to remain valid for a person on active duty in the armed forces, it is essential that the license must not be suspended. Active military service can often lead to unique situations regarding licensing, and maintaining a valid, unsuspended driver's license is crucial to ensure that service members can drive legally without any interruptions, especially when they return home. A suspended license may lead to legal repercussions and complicate their ability to drive upon their return from duty.

The other conditions mentioned do not specifically pertain to the requirements for maintaining the validity of a driver's license while on active duty; therefore, they do not hold the same weight regarding the legal standing of the license during military service.
