Unabme to run docker without sudo

I am unable to run docker without sudo.

Got permission denied while trying to connect to the Docker daemon socket at unix:///var/run/docker.sock: Get http://%2Fvar%2Frun%2Fdocker.sock/v1.25/containers/json: dial unix /var/run/docker.sock: connect: permission denied


I added docker to user group

sudo usermod -aG docker $USER

Still i am unable to run without sudo.
