You are driving on an unrestricted dual carriageway at night and see a slow-moving vehicle ahead with a flashing amber beacon on its roof. What should you do?

Explanation

According to the Highway Code Rule 225, flashing amber beacons are used on slow-moving or stationary vehicles, or vehicles with abnormal loads. You should approach with caution, slow down, keep a safe distance, and only overtake when you are sure it is safe to do so. You must not drive aggressively, follow too closely, or try to force your way past.
