There are a number of unspoken rules out on the roads, with most people offering common courtesy to other drivers, pedestrians, and cyclists.
However, a study by the car insurance team at Comparethemarket has found one common expression of on-the-road politeness could leave drivers facing hefty fines and penalty points. The research also reveals many drivers are unaware that certain actions which are often perceived as good manners, are actually illegal.
Julie Daniels from Comparethemarket has warned some "unofficial rules" could leave you out of pocket, as reported by Devon Live.
