Q: You're riding a motorcycle that's towing a trailer. What should you do before turning right onto a dual carriageway?
Correct answer:
Assess the width of the central reservation
Explanation
Before emerging right onto a dual carriageway, make sure that the central reservation is wide enough to protect both your motorcycle and its trailer. If it isn't, you should treat it as one road and check that it's clear in both directions before pulling out.
