As Oregon’s rainy season takes hold each November, commercial trucks and passenger vehicles share roadways under increasingly hazardous conditions. Heavy rain, standing water, fog, and reduced daylight all heighten the risk of serious truck collisions across Portland, Gresham, Clackamas, Troutdale, and Happy Valley

At Peterson Law Offices, we’ve represented injured Oregonians since 1991 — including those involved in devastating truck accidents. Our decades of experience show that while weather plays a part, most of these collisions stem from preventable negligence such as poor maintenance, driver fatigue, or unsafe speeds for the conditions. 

The Impact of Rain and Hydroplaning 

Oregon averages more than 150 days of rain each year, with November ranking among the wettest months. When roads are slick, truck tires lose traction faster, and large vehicles require significantly longer distances to stop. Even at moderate speeds, hydroplaning can cause multi-vehicle pileups on highways like I-5, I-205, and Highway 26. 

Truck drivers have a legal obligation to adjust to road conditions — slowing down, increasing following distance, and using headlights appropriately. When they fail to do so and cause an accident, that behavior can constitute negligence under Oregon law. 

Tire Wear and Maintenance Issues 

Tractor-trailers depend on proper tire maintenance for safety. During the fall, fluctuating temperatures cause tire pressure to drop, increasing blowout risk. Inadequate inspections or worn treads can turn wet pavement into a serious danger zone. 

Companies operating commercial fleets are responsible for regular maintenance and recordkeeping. If an accident results from bald tires, faulty brakes, or poor equipment upkeep, both the driver and the trucking company may be held liable. An experienced Oregon truck accident lawyer can investigate maintenance logs and mechanical reports to identify where negligence occurred. 

Cargo Shifts and Overloaded Trailers 

Improperly loaded cargo is another leading cause of truck accidents during the rainy season. When weight isn’t distributed evenly, a truck can fishtail, jackknife, or roll over on wet roads. Oregon’s steep grades, especially around Clackamas County and the Columbia River Gorge, make these risks even greater. 

Drivers and loading companies share the duty to ensure cargo is secured according to federal and state regulations. A failure at either stage can lead to catastrophic accidents affecting multiple vehicles. 

Visibility and the Dangers of Fog 

Fog is common across Troutdale and the I-84 corridor during late fall, creating unpredictable visibility levels. Large trucks with high-beam headlights can temporarily blind smaller vehicles, while their own limited sight distance makes lane changes risky. 

In poor visibility, federal trucking regulations require drivers to use hazard lights and reduce speed. When truck operators fail to adapt, serious rear-end or side-impact collisions may occur. Victims often suffer life-changing injuries, from spinal damage to traumatic brain injuries. 

Fatigued Driving in Long-Haul Operations 

The darker months can also lead to increased fatigue among long-haul drivers. Shorter days disrupt circadian rhythms, and the pressure to meet delivery deadlines can tempt drivers to skip rest breaks. Fatigue impairs reaction time, coordination, and judgment — all critical when operating an 80,000-pound vehicle. 

Federal Hours of Service regulations exist to prevent these risks, but violations are common. Peterson Law Offices has seen how fatigue-related crashes devastate Oregon families, particularly when drivers falsify logbooks or work excessive hours. 

Proving Negligence in a Truck Accident Case 

Truck accident investigations are complex and often involve multiple liable parties — the driver, employer, equipment manufacturer, or even a third-party contractor. To prove negligence, your attorney may collect: 

  • Electronic logging device (ELD) data showing hours worked 
  • Maintenance records and inspection reports 
  • Weather data and road condition evidence 
  • Witness statements and dashcam footage 

A qualified Oregon personal injury law firm can also work with accident reconstruction experts to show how weather conditions and human error combined to cause the collision. 

Common Injuries in Weather-Related Truck Crashes 

Truck accidents often result in severe or permanent injuries due to the force of impact. Victims may experience: 

  • Traumatic brain injuries (TBI) 
  • Spinal cord damage or paralysis 
  • Broken bones and crush injuries 
  • Internal organ damage 
  • Emotional trauma and PTSD 

The financial and emotional toll of these injuries can be overwhelming. That’s why it’s critical to seek professional legal representation immediately after a crash. 

Steps to Take After a Truck Accident 

If you’re involved in a collision with a commercial truck: 

  1. Call 911 and report the accident. 
  1. Seek medical attention, even for minor symptoms. 
  1. Document the scene, including road conditions and truck markings. 
  1. Avoid speaking to the trucking company’s insurer before consulting a lawyer. 
  1. Contact Peterson Law Offices to protect your rights. 

Trucking companies often send investigators to accident scenes within hours. Having your own advocate ensures your side is represented from the start.
