My family and I will be driving to a new state this Ramadan. The distance is 1500 km (14 hours) drive. We will divide it over 3 days. Should we fast or not?

It is permissible for you to refrain from fasting during the 3 days you will be on your way and you must make up the missed fast days later though it is better to fast if you are able to.
And God Almighty knows best.
