London worst for uninsured drivers
According to the Motor Insurers' Bureau (MIB), the West Midlands also has six of the 10 worst-offending postcodes, while nearly half of all vehicles registered in the BD3 postcode of Barkerend in Bradford, West Yorkshire, were flagged as being uninsured.
Overall, the MIB estimates more than 1.7 million motorists broke the law during 2008 by driving despite not having motor cover.
Says MIB boss Ashton West: "The fact that 1.7 million motorists still take to the roads without insurance is staggering; but there is no doubt that the number of drivers caught each year is increasing significantly, so drivers simply cannot afford to be complacent.
"Indeed, the number of drivers across the UK who were caught without insurance last year would fill Wembley Stadium more than twice. The message to motorists is clear: driving uninsured is simply not worth the risk."
