The correct answer is the driver's license, which can be recognized under reciprocal agreements between states. Many states have established provisions to honor each other's driver's licenses, allowing individuals to operate vehicles legally across state lines without needing to retake driving examinations. This mutual recognition provides convenience for residents and travelers, facilitating easier movement and compliance with road usage regulations.

In contrast, professional licenses, business licenses, and construction licenses may not have uniform recognition across states. Each state often has its own requirements and methods for licensing professionals in various fields, leading to differences in standards and examinations. As a result, these types of licenses do not typically operate under reciprocal agreements in the same way that driver's licenses do.
