One in 13 young front seat vehicle passengers in England does not wear a seat belt, new figures suggest.  Department for Transport (DfT) research conducted in autumn last year indicated 8.0% of people estimated to be aged between 14 and 29 were not buckled up while sitting next to a driver. That compares with 4.8% of those aged 30-59, and 1.3% of those aged 60 and over.
