Young drivers in third of fatal Wiltshire crashes
More than a third of fatal road crashes since 2009 in Wiltshire involved drivers aged under 25, police figures have shown.
During that time, 21 young people were killed and young drivers were involved in more than 1,200 crashes.
Claire Barnett's son James was killed in a road incident in Potterne when he was 20.
She said she believed that more thorough testing and probation periods could help save lives.
The Association of British Insurers is calling for new drivers not to be given full licences straight away.
