How to get the full report
This document reviews the number of collisions, vehicles involved, and casualties (fatalities and
injuries) resulting from heavy truck collisions for each of straight trucks (greater than
4,536 kg) and tractor-trailers. The report also presents tables and charts showing the
distribution of fatalities and injuries by type of heavy truck, and road user class, collisions by
accident configuration, and discusses external factors relating to the collisions. While the causes
of collisions cannot be determined from the Transport Canada database, Traffic Accident Information
Database (TRAID), this report discusses some of the contributing factors.
Summary Findings
Over the five-year period:
- An average of 43,843 collisions1 involving heavy trucks occurred each
year – averages of 24,450 and 20,006 for straight trucks and tractor-trailers, respectively. Straight
trucks averaged 168 fatal, 4,467 personal injury, and 19,815 property damage only collisions, while
collisions involving tractor-trailers averaged 296 fatal, 3,827 personal injury, and 15,883 property
damage crashes per year.
- The number of heavy trucks averaged 46,239 or 4 percent of all vehicles involved in all collisions.
Straight trucks accounted for 55 percent of the heavy trucks involved, while tractor-trailers accounted
for the remainder, 45 percent.
- Heavy trucks in fatal collisions represented an average of 11 percent of all vehicles in fatal
collisions per year. Straight trucks accounted for an average of 174 per year or 4 percent, and
tractor-trailers accounted for an average of 318 per year or 7 percent of all vehicles involved in
fatal collisions.
- Of all vehicles in personal injury collisions, heavy trucks accounted for an average of 8,651
vehicles or 3 percent per year. Straight trucks amounted to an average of 4,617 per year or 1.6 percent,
while tractor-trailers represented an average of 4,034 per year or 1.4 percent of all vehicles involved
in personal injury collisions.
- Approximately 75 percent of all collisions are property damage only collisions each year. In these
collisions, heavy trucks represented an average of 37,096 vehicles or 4.3 percent per year of all
vehicles in property damage only crashes. Straight trucks accounted for an average of 20,491 vehicles
per year or 2.4 percent, while tractor-trailers amounted to an average of 16,605 per year or 1.9 percent
of all vehicles involved in property damage only collisions.
- All vehicles involved in collisions with heavy trucks represented averages of 21.7 percent
of all vehicles in fatal collisions, 5.8 percent and 7.6 percent of all vehicles in personal
injury and property damage collisions, respectively.
- The number of fatalities in collisions involving heavy trucks averaged 554, comprised of 65
(11.8 percent) heavy truck occupants, 444 (80.1 percent) occupants of other vehicles, and 45
(8.2 percent) pedestrians. Fatalities in heavy truck collisions averaged 17.6 percent of all
road user fatalities and averaged 1.215 fatalities per collision involving a heavy truck, compared to
1.135 fatalities per collision not involving heavy trucks.
- An average of 11,848 persons suffered non-fatal injuries in collisions involving heavy trucks,
representing 5.1 percent of all road users injured. On average, these victims of heavy truck
collisions consisted of 2,960 (25 percent) heavy truck occupants, 8,573 (72.4 percent)
occupants of other vehicles, and 315 pedestrians (2.7 percent).
- Drivers of automobiles, light trucks and vans were recorded as having a driver condition "other
than apparently normal" 4.25 times more frequently than the drivers of heavy trucks in fatal
collisions.
- In fatal crashes, drivers of automobiles, light trucks and vans were recorded as having a driver
action "other than driving properly" 2.74 times more frequently than the drivers of heavy trucks.
