DO NOT DISTURB turns itself on. Can I disable this feature?

[Android Central Question]

I have a Galaxy A3 2016. In the last two months DO NOT DISTURB turns it self on when I am in a car and been down the road about 1/2 mile. But it does not always do it. I thought that by turning off my 'Location' it would stop it. This did not work. So there is an app running knowing I am travelling.
