## How Does The Maximum Driving Distance Method Work?
You will need to **enter your key location** and **pick the maximum driving distance** approved to deliver in the delivery conditions setting.
Your customers will need to enter their address in the widget to check if delivery is available
If the address that the customer entered in the widget falls within the driving distance you specified in your delivery condition settings, he will be able to proceed
If the address that the customer entered in the widget is out of the radius you specified in your delivery condition settings, he will be unable to proceed further

**Step 1**: At the DELIVERY LOCATION VALIDATOR section, tick to choose **Maximum driving distance**
**Step 2**: Enter your valid Google API key
**Step 3**: Type your key location to set the driving distance for
**Step 4**: Pick the country for your key location
**Step 5**: Pick the state/city for your key location
**Step 6:** Tick to choose means of transportation that wouldn't be counted in driving distance
