To explore the relationship between reported road traffic RTIs in adolescence and a range of background personal and family risk factors in early life, and to investigate the characteristics of children who had repeat road traffic incidents.


ALSPAC is a longitudinal birth cohort study based in the South West of England, which started in 1991. At several points during childhood, parents and children completed questionnaires regarding their involvement in road traffic RTIs in the previous 12 months, and their journeys by car, bus, train and cycle, as well as about preventive practices in the road environment.

Key Findings:

  • The risk factors for RTI involvement between 13 and17 years old are mainly:

    • Intrinsic to the young person (males, attitude to sensation-seeking); and,

    • Related to family background (single parenthood, higher number of siblings and lower level of parental monitoring) and some or related to the external environment (stressful life events in girls).

  • The young people who had RTIs at 13 or 16 years were twice as likely to have had a previous road traffic injury before the age of 11 and had distinct profiles:

    • Associations with conduct difficulties in childhood;

    • Absent fathers; and,

    • Family dissatisfaction with the neighbourhood lived in.
