What Should I Do?
Give yourself the best chance of avoiding delays by checking road conditions if driving, leaving extra journey time, or amending plans if necessary. Make sure you know how to switch on your fog lights, and check they are working before setting off on your journey. Bus and train services, as well as flights may also be affected; check for updates from your travel company and follow their advice.
