Flashing headlights can be seen up and down the UK's roads, but when should we actually flash our headlights. This was a question asked by one keen listener and that's what I answer today.
I'll cover the specific theory test question and provide other examples of when you shouldn't do it, such as trying to warn other drivers about a police speed van. I also discuss the effect peer pressure has on drivers and how this can influence them to make bad choices.
