Yes, if you have any roads near you where you can just cruise around in low-traffic that would be good to get comfortable with.
When I first got my road bike it was a little scary for me, i went to the big school parking lots on Sundays when they were almost empty. That's where I could really practice stopping and starting, and the best was riding figure 8's of various sizes, getting used to turning and leaning, stopping suddenly, starting up. That practice really helped me when i later got into busier roads and traffic.
