We do not offer parental control options within our service at this time. However, ratings and other relevant aspects of a program's content are displayed at the beginning of a program. Depending upon how you're watching a TNT, TBS, or truTV programming, you might be able to use parental controls within your device to limit what content can be watched in your household.
To learn more tools and information on parental control, please visit http://www.tvguidelines.org/ and https://www.thetvboss.org/.
