Study Shows Truck Accidents Affected by Time, Season

Jul 28, 2010

California-based safety company DriveCam Inc. conducted a study on long-haul truckers, examining the frequency of collisions and near-collisions among the group. Their findings: Trucks are significantly more likely to be involved in a collision or near-collision depending on the season and time of day.

DriveCam’s data shows that the rate of collisions and near-collisions is quite low during the first half of the year, staying at around 1% from January to June and rise drastically beginning in July, peaking at 18% and remaining over 14% through the month of November.

The time of day was also a significant factor in crash risk, with collisions peaking between 3 and 4 PM, and again between 8 and 9 PM.  The least likely time for an accident?  Between 11 PM and 9 AM.  Tuesday and Friday proved to be the most dangerous days of the week, with rates of 21% and 20% respectively.

“Crash statistics don’t lie. It makes sense that driving gets riskier as the day goes on,” David Kelly, former Acting Administrator of the National Highway Traffic Safety Administration (NHTSA) told FleetOwner.

“For example, people aren’t generally getting drunk in a bar in the morning,” he said. “While it happens, it is much more predominant at night. People are also getting more tired as the day progresses. Visibility is also more of an issue as it gets darker.”
