Transport Truck & 18-Wheeler Accident Lawyer
Tractor-trailers, semis and big rigs cause the most devastating crashes on Ontario's highways. If one has injured you or someone you love, we can help you hold the driver and the trucking company accountable.
On highways like the 401, 400, QEW and 407, a moment’s inattention behind the wheel of an 18-wheeler can change lives forever. Transport truck collisions — jackknifes, rear-enders, underride crashes, rollovers and blind-spot sideswipes — tend to produce the gravest injuries we see.
When a transport truck is involved, the investigation has to go well beyond the driver. We examine the trucking company's safety record, the driver's hours-of-service logs, the truck's electronic data, and its maintenance history — because any one of them can reveal why the crash happened and who should pay for it.
Common causes of transport truck crashes
- Driver fatigue — long hauls and unrealistic delivery schedules push drivers past safe limits.
- Improper or overloaded cargo — shifting or excess weight makes trucks unstable and lengthens stopping distance.
- Inadequate maintenance — worn brakes and bald tires on a 40-tonne vehicle are catastrophic.
- Blind spots and unsafe lane changes — "No-Zones" around large trucks hide entire vehicles.
- Speeding and distracted driving — the same errors are far deadlier in a heavy truck.
Underride and rollover crashes
Two of the most dangerous transport-truck collisions are underride crashes, where a smaller vehicle slides beneath the trailer, and rollovers, where a truck tips onto surrounding traffic. These cases often involve questions about trailer guards, loading and driver training — technical issues we know how to investigate.
How we build a transport truck claim
We act quickly to preserve the truck's electronic control module data and the driver's logs, retain collision-reconstruction and medical experts where needed, and pursue every responsible party — driver, carrier, owner and others — while managing your accident benefits so your treatment never stalls.
Answers
Transport truck & 18-wheeler crashes — FAQs
What counts as a transport truck or 18-wheeler?
People use many names — transport truck, tractor-trailer, semi, big rig, 18-wheeler, or 'the trucks on the 401.' Legally they're heavy commercial motor vehicles, and crashes involving them are handled the same way: with a focus on the trucking company's records, the driver's hours, and the electronic data from the truck.
Why are transport truck crashes so serious?
A loaded tractor-trailer can weigh up to 40,000 kg, compared with roughly 1,500 kg for a typical car. That difference in size and momentum means occupants of smaller vehicles absorb enormous force — which is why transport truck crashes so often cause catastrophic or fatal injuries.
Can the trucking company be responsible, not just the driver?
Frequently, yes. A trucking company can be liable for the actions of its driver and for its own failures — pushing unrealistic schedules, skipping maintenance, poor hiring, or ignoring hours-of-service limits. Identifying company-level fault often increases the compensation available.
What is hours-of-service, and why does it matter?
Commercial truck drivers in Canada are limited in how many hours they can drive before resting, and must keep logs. When a driver exceeds those limits, fatigue becomes a factor — and the logbook (or electronic logging device) can become powerful evidence in your claim.
