It doesn't always go against the emergency vehicle. The Police will investigate and it will be referred to the CPS for a decision as to whether there is sufficient evidence to summonses for any offences disclosed and this will only happen if it is the public interest to do so and other guidelines are met. 1994(ish). Lea Bridge Road, E10 Ambulance on blues and twos passing stationary line of traffic on wrong side of road (as they are entiltled to do - if safe to do so) is hit on the nearside by a car turning right through a gap in traffic. Result no one injured - car driver got 6 points and £200 for driving without due care. I was the guy that instigated prosecution - if you can't see a big white thing making a lot of noise with pretty lights going - explain to the Magistrate why you should keep your driving licence coz I want it off you. But prosecuting rta's is boring so I do Police computers now
