As a means of comparison, shown in Table 10 is a summary of the effects of lowering speed limits on crashes. The effects of raising speed limits are shown in Table 11. In general in other countries, studies of the effects of raising speed limits generally indicate that vehicle speeds and crashes increase,
but much of the data is from freeways in the United States and much of the crash data is for fatal crashes. Due to the relative low number of fatal crashes in British Columbia during the study periods, only total crashes were considered in the analysis.
