A big rig collision involves a heavy commercial vehicle, often caused by a wide range of factors that differ from passenger car crashes. Whether you are a seasoned truck driver, considering a job in the trucking industry, or simply an everyday road user, understanding the common causes of big rig accidents can mitigate future tragedies. At Jingozian Law Group, we specialize in truck accident cases, helping victims get the justice they deserve. Here are common causes of rig crashes that truck accident attorneys and insurance adjusters investigate.

Driver Fatigue

Did you know that fatigue is one of the leading causes of truck accidents? This is a common occurrence in most cases, as personal injury lawyers investigate when determining who’s liable. Driver fatigue is usually linked to long hours on the road, irregular sleep patterns, and tight deadlines. Operating big rigs requires a sound mind and impeccable reaction time to make safe trips. However, fatigue can increase the chances of a driver making errors while operating a commercial vehicle, increasing the risk of accidents.

Improper Loading or Overloading

Perhaps the most overlooked cause of big rig crashes is improper loading or overloading of cargo. While commercial trucks can handle a significant amount of weight, they have limits to avoid stability and handling issues. When freight is not secured properly or exceeds the set weight limits, it can cause the vehicle to shift during transit and lose control. If a rig rolls over and causes a devastating collision, a personal injury lawyer in Canoga Park, CA can investigate to determine if loading is the cause and ensure that those liable are held accountable.

Poor Maintenance

Commercial vehicles are usually under more scrutiny than small passenger cars. Whether you are the owner of a truck or hired by a trucking company, keeping up with regular maintenance and inspections is essential to prevent safety hazards. The last thing you want is a mechanical problem during operation, forcing you to react in the middle of traffic or properties. If you allow small issues to escalate into bigger problems, your chances of an accident increase dramatically. In the case of a collision, a truck accident attorney can send a spoliation letter to preserve black box data, maintenance records, and other pertinent information indicating inadequate maintenance. Even a faulty steering system, worn-out brakes, or defective tires can create the ideal conditions for a crash when you least expect it.

Weather Conditions

Sometimes, the cause of a big rig crash is not the driver, the trucking company, or the local transit company. Adverse weather conditions, such as heavy rain, snowfall, ice, or fog, can create hazardous road conditions. This is particularly true for commercial vehicles, which haul cargo across the country. In some areas that experience extreme changes, drivers may experience slippery roads, reduced visibility, and decreased traction. These factors make it difficult for truckers to adjust, increasing the likelihood of collisions. If the crash is a result of natural causes, a personal injury attorney can prove that it was an “act of God.”
