Drivers are advised by the Highway Code to be cautious when emergency vehicles with flashing lights and sirens approach. It is important for drivers to pull over safely to let these vehicles pass. However, there are certain places where drivers should avoid stopping, including bus lanes, yellow box junctions, and areas with red traffic lights. Failing to comply with these rules could result in fines and penalty points on your license. Following the guidelines and ensuring safety on the road is crucial to avoid legal consequences.
