Differences in characteristics and outcomes between those with and without prior traffic offences (N = 10,330).
Table 2.
Relationships between cumulative number of prior traffic offences, demerit points, or specific types of traffic offences of a licenced motorcycle rider or motor vehicle driver and risk of road trauma leading to intensive care admission or death (n = 1020, N = 7137).

Dotted lines delineate 95% confidence interval.
Table 3.
Factors associated with readmissions to the State Trauma Centre from injury after road trauma among those who recovered from their first injury during the study period (n = 160, N = 10,063).
Fig 3.
Differences in number of traffic offences between before and after road trauma requiring intensive care unit admission.
These results remained unchanged (reduction in number of traffic offences = 1.6, 95% confidence interval 1.1–2.0, p = 0.001) after including only those with at least one traffic offence after their injury.
Fig 4.
Differences in number of demerit points between before and after road trauma requiring intensive care unit admission.
This result remained unchanged (reduction in number of demerit points = 3.7, 95% confidence interval 2.9–4.5, p = 0.001) after including only those with at least one traffic offence after their injury.
