It's worth noting that Turktrust is not a government agency, and ego.gov.tr is simply the website of the municipal department that controls traffic and public transportation in the capitol city of Ankara. The likelihood that they would use these certificates for malicious purposes is virtually zero.
I'm not an expert on how spy agencies operate, but if they were buying a certificate like this to spy on people I don't think they'd ask to have their own name put on it?
Turkey often blocks websites [1] so they obviously have a problem with some of Google's operations, and have the capability to mess with regular citizens' internet connections.
