Drivers are being warned of a little-known error involving emergency vehicles that could result in a fine of up to £1,000.
The Highway Code says that motorists should give way to emergency service vehicles using flashing lights, including ambulances, fire engines and police vehicles. But other regulations remain in place while letting emergency vehicles through and some illegal manoeuvres incur a hefty fine and penalty points on your license.
Moving into a bus lane, stopping in a yellow box junction and driving through a red light to make way for emergency vehicles are all likely to lead to a fixed penalty notice, with fines and points escalating for those who fail to provide drivers' details or take the case to court and lose.
