Please proceed with caution, i learnt the hard way in Jan 2008.
Flooded road, stopped and checked other cars, all seemed fine just coming above bottom of bumpers, wait until no oncoming traffic, centre of road, get half way, artic lorry decides he can still go through. The wave he created buried me water up windscreen, result one destroyed mint 36k anni pd. 
Result was an insurance claim on my policy as the lorry didnt stop or get his reg. The bill for new engine came to approx £5600 from VW, was borderline write off due to cost!
Please be careful!!!!!! If work will not provide suitable vehicle and the roads are not passable in your car, Tough, take a photo if they argue!
If you need to get through, take wellies and a stick, check the water first.
holy sh*t that was bad dude
