Blocking Drive access

[Jasebta]

I'm supposed to be going out for a meal and there's a van blocking my drive.. It's a dropped kerb so as far as I was aware they shouldn't be parked there?
Is there any way I can report the owner for them to move the van asap as otherwise I'll have to get a taxi because I can't get the car off the drive
Any advice please?

Loving the advice

I got a taxi.

Seems there was a bit of a domestic at a neighbours (who is a police officer). There were two more police cars and another van down the road, all more reasonably parked, but I didn't want to interrupt. There was plenty of space behind them not to be blocking any road access.
