Anyone who regularly commutes on two wheels probably already has an idea of when traffic feels most dangerous. Now, 2024 data shared by the National Highway Traffic Safety Administration puts numbers behind that feeling, showing that fatal motorcycle crashes are heavily concentrated during the afternoon and evening.
According to NHTSA’s infographic, the deadliest three-hour period is from 6 p.m. through 8:59 p.m., accounting for 23 percent of fatal motorcycle crashes. Immediately behind it is the 3 p.m. to 5:59 p.m. window at 21 percent, meaning those two periods alone account for 44 percent of the total.
The numbers fall considerably outside that window. Fatal crashes were distributed at 8 percent from midnight to 2:59 a.m., 4 percent from 3 a.m. to 5:59 a.m., 6 percent from 6 a.m. to 8:59 a.m., and 8 percent between 9 a.m. and 11:59 a.m.
Risk begins climbing significantly after midday, with 15 percent occurring between noon and 2:59 p.m. Another 16 percent happened between 9 p.m. and 11:59 p.m., making the afternoon and evening clearly stand out in NHTSA’s breakdown.
6 P.M. To 9 P.M. Is The Deadliest Window
There are several potential reasons why the early evening stands out, although NHTSA’s graphic itself does not assign causes to the time-of-day pattern. The 6 p.m. to 9 p.m. period can combine heavy traffic, commuters heading home, changing light conditions, and, depending on the season and location, sunset.
The preceding three hours also overlap with afternoon rush-hour traffic in many parts of the country. More vehicles sharing the road creates more opportunities for conflicts, while motorcycles are inherently easier for motorists to overlook because of their smaller visual profile.
NHTSA specifically advises riders to make themselves visible and avoid traveling in other vehicles’ blind spots. Drivers, meanwhile, are encouraged to look twice for motorcycles and remember that they are sharing the road with considerably more vulnerable users.
Motorcyclists Remain Disproportionately At Risk
The time-of-day statistics sit within a larger motorcycle safety problem in the United States. NHTSA reports that 6,228 motorcyclists were killed in traffic crashes during 2024, representing 16 percent of all traffic fatalities.
Exposure makes those numbers even more concerning. On a per-vehicle-mile-traveled basis, NHTSA says motorcyclists in 2024 were almost 27 times as likely as passenger-car occupants to die in a crash and nearly five times as likely to be injured.
Those figures help explain why defensive riding matters regardless of what the clock says. A mistake that results in bent bodywork for a car can have dramatically different consequences for someone without a passenger compartment, airbags, or crumple zones surrounding them.
The Graph Doesn’t Mean Morning Riding Is Safe
It is also important to understand what NHTSA’s percentages do and do not show. The chart describes when fatal motorcycle crashes occurred, rather than calculating a rider’s individual risk per mile or per trip during each time period.
That distinction matters because motorcycle traffic itself is unlikely to be evenly distributed throughout a 24-hour day. For example, the 4-percent share between 3 a.m. and 5:59 a.m. does not automatically mean riding during those hours is safer on a per-mile basis; there may simply be far fewer motorcycles on the road.
Other factors can also dramatically change crash risk. NHTSA reports that 40 percent of motorcycle riders who died in single-vehicle crashes during 2024 were alcohol-impaired, demonstrating that time of day is only one piece of a much larger safety picture.
Staying Visible Can Make A Difference
For riders, NHTSA recommends positioning motorcycles where other motorists can see them and avoiding blind spots. Using appropriate protective equipment and a DOT-compliant helmet provides another layer of protection if avoiding a collision proves impossible.
Drivers have an equally important role, particularly during those busy afternoon and evening periods. Checking mirrors and blind spots carefully, paying attention when changing lanes, and actively looking for motorcycles can help prevent the classic scenario where a driver simply fails to notice a rider.
The 2024 numbers ultimately reinforce something experienced motorcyclists already understand: the evening commute deserves particular attention. With 44 percent of fatal motorcycle crashes occurring between 3 p.m. and 9 p.m., that familiar ride home coincides with the largest concentration of deadly crashes shown in NHTSA’s data.
If you ride, do you feel noticeably less comfortable on the road during the evening commute? Do these statistics change when you would choose to take your motorcycle out?
