Three million

During the 12 years to 2011, the police recorded more than three million road casualties in Great Britain.

More than 36,000 people lost their lives and another 373,985 were seriously injured.

However, the police figures do not reflect the full scale of death and injury on the roads. Many incidents go unreported.

The best official estimate of the total number of people killed and injured in road collisions each year is a massive 730,000.

While the price paid by the victims and their familes is inestimable, the annual cost to the economy is between £15bn and £32bn.
