How the tests are done
The British Insurance Car Security Awards are the toughest, most comprehensive assessment of car security today.
The tests, carried out by experts at motor insurance research centre Thatcham, cover two main areas: 'theft from' a car and 'theft of' a car. Top marks show as a double five-star rating.
