You’re riding on a motorway. There’s a slow-moving vehicle ahead. On the back, you see this sign. What should you do?

Explanation: If this vehicle is in your lane, you'll have to move to the left. Use your mirrors and signal if necessary. When it's safe, move into the lane on your left. You should always look well ahead so that you can spot such hazards early, giving yourself time to react safely.
