There is an element of risk both ways. The driver has the risk of driving an unknown vehicle, maintained, MOTd and insured by someone else, so needs assurance/paperwork to show the vehicle is legal.
The owner will need to trust/see paperwork that the driver is licenced and a good driver etc.
Imagine the scenario:
A driver helps a stranded owner and omits a claim they had on their insurance (by mistake) he then goes on to have an accident and the insurance refuses to pay. The owner of the van doesn't want to lose his £50K van, so sues the driver.
I am not saying it shouldn't be done, just pointing out the risks.
