The table below is from
and shows the time of day in which both the fatal and non-fatal accidents occurred. The data indicates that most accidents occurred between 17h01 and 18h00, with the most accidents taking place from 14h01 to 20h00. It is not possible to state whether a given time of day is "more dangerous" than any other time since PTW rider exposure data (i.e., number of riders on the roadway at all hours of the day) is not available
. Most of the fatal accidents occurred between 12h01 and 22h00, with the most frequent number of cases taking place between 19h01 and 20h00. The data shown in Figure 3.2 may be found in datatables page, Table C.2.
According to the U.S. Department of Transportationís National Highway Traffic Safety Administration (NHTSA, Motorcycle riders killed in traffic crashes at night were nearly 4 times more likely to have BAC levels at or over 0.08 percent (48 percent)
than those killed during the day (13 percent).
According to the Insurance Institute for Highway Safety (IIHS), riders of ďsupersportsĒ motorcycles have driver death rates per 10,000 registered vehicles nearly four times higher than for drivers of other types of motorcycles.
Also attached is another table showing time of day for all motorcycle injuries and deaths. the evening was also very high in the statistics.
Unfortunately, none of the surveys show the % of riders per time of day, so for example, if 80% of the miles put on motorcycles are driven between 5pm and 1 am, the # of accidents would be higher, but does that correlate to night driving being safer? Then when you factor in BAC etc, there is no survey or evidence that riding at night vs riding during the day is safer especially if you factor out BAC.
