It is generally easy to drive on Provo even on the left side. There are no street lights - only a few round abouts, yield and stop signs. If you are unsure, stick to the left, by the curb, which is the slower lane. Give yourself about 15 min and you'll feel right at home. There isn't much tourism signage either and you'll find that some remote beaches are more difficult to locate but so worth it when you do!
