What major program was suspended in January 2010 concerning driver's license renewals?

The renewal by mail program was suspended in January 2010 as part of an effort to improve security and ensure that the identity of individuals renewing their driver's licenses could be properly verified. This decision was made to enhance the overall integrity of the licensing process, as renewing by mail could pose challenges in confirming the authenticity of applicants, potentially leading to issues such as identity theft or fraud.

In contrast, the other options involved processes that continued to be available but may not have addressed the same concerns regarding identity verification. In-person renewals allow for direct identification of the individual, while online renewals, although convenient, typically have their own security measures in place. The driving skills test focuses on the individual's ability to operate a vehicle safely and was not related to the renewal processes. Thus, the suspension of the renewal by mail program highlights the importance of security in issuing driver's licenses.
