If you in a vehicle crash and can see bodies and people trapped in wrecks and someone asks you what service you need which are you going to pick?
It can be a confusing question, always stalls me for a second, probably my brain parsing "don't say something sarcastic".
I plump for "ambulance" then they are on the way and I can tell them to send the fire brigade if needed. The police always seem to turn up at an accident or any incident so guess it just pops up on their RSS feed (or equivalent) and they dispatch someone, if for no other reason than to marshal traffic.
One tip I have is to always carry one of those cotton hi-vis waistcoats in the car. Drivers will be more inclined to let you control traffic flow round / past an accident than if you try without. And it's safer.
