TLS 1.0 and 1.1 Support Ending

If your browser does not have TLS 1.2 or higher enabled after November 1st, 2017 when TLS 1.0 and TLS 1.1 is disabled, you will not be able to access any content on NHTSA.gov, including ratings, recalls, and other news.

Transport Layer Security (TSL) is a standard developed by the Internet Engineering Task Force (ITEF) that aims to minimize the risk of sensitive data being intercepted and used for malicious purposes during transmission over insecure networks. This protocol is seamlessly implemented behind the scenes in a wide variety of applications people use every day – from desktop web browsers to mobile applications. TLS works by creating a secure connection between the client and the NHTSA.gov server so that any data passed between them is protected.

Vulnerabilities were found in the TLS 1.0 and TLS 1.1 protocols by the Internet Engineering Task Force that led to the ITEF releasing TLS 1.2 to remedy those issues. In order to access NHTSA.gov after November 1st, 2017, ensure that TLS 1.2 or later is enabled and supported by your browser. Free tools like How's My SSL and Qualys SSL Checker provide services that check for TLS vulnerabilities. To enable a newer protocol, follow these instructions provided by GeoTrust. By requiring TLS 1.2 or later to be used when connecting to NHTSA.gov, we are making interactions with this site safer.
