Once you've completed the previous steps, your driving directions are available by scrolling down on the page. One final step I recommend doing before you start driving is to check out Street View.
As you hover your mouse over each step in the directions, you may see a little person button appear. By clicking on that, you'll go into Street View mode, so you can check out what your route looks like from the ground. Be sure to check out your destination if you've never driven there, just to make sure there are not tricky entrances or subtle signs.
At this point, you may also want to print off these directions. The print button is on the upper right area of the window next to the Send and Link button. You can use the Send button to send directions to someone by email, and you can use the Link button to embed a map on a Web page or blog. If you're an Android user, you may want to save your directions to My Maps and use your phone as a built in GPS navigation system.
