The probability distribution of the time intervals between two consecutive accidents is investigated, based on the road accidental records of the Great Britain. A universal description is obtained for different roads, by rescaling the probability distribution and time intervals. The scaling curve is found to deviate from the Gaussian distribution, but it is well fitted by a stretched exponential function. Long-range time correlation is revealed for the interevent series. Moreover, gender similarity is found for the small accidental intervals, while for the large intervals, the female drivers are observed to present a higher probability than the male drivers.
