The human cost of Britain's crumbling roads. 5 live Investigates hears from the victims and families of those who've been killed in accidents involving potholes. The programme has learned local authorities have had to pay-out £38 million pounds in compensation over the last five years - but that's significantly less than the £9 billion pounds some say it will cost to bring our roads up to scratch. Most of the compensation goes to motorists who've suffered damage to their vehicles. But the biggest pay-outs are reserved for cyclists - the most vulnerable road users of them all. Nearly £7m paid-out to them and their families in the last 5 years.
