It never hurts to revisit the rules. They are ever changing and it's likely that if you took your written driving test in the late 80's, you may not be fully aware of changes that have been made.
So, do yourself a favor. Visit www.dmvflorida.org or www.ntsb.gov or www.flhsmv.gov to refresh and renew your awareness of traffic and safety. It can save your life and others.
