There are many different causes of semi-truck accidents. The ones we see most common in Shelby County include: Improper Merging or Failing to Signal Truck drivers commonly fail to merge properly into traffic or fail to use turn signals while making turns. It is common for cars to merge too closely to a semi-truck, and the truck cannot slow down quickly enough to give room. Driver Fatigue Fatigued truckers are much less likely to respond appropriately to emergency situations. They may become confused or disoriented, causing them to lose control of their vehicle or not react in a timely manner. Distracted Driving Distracted driving is another major cause of truck crashes. Drivers may text or talk on cell phones, read maps or play games on smartphones, or eat food or drink beverages while operating a large vehicle. Influence of Drugs Drugs and alcohol can have a major effect on driving abilities. They often slow down response times, and with semi – trucks, it takes an extended amount of time to bring these large vehicles to a stop. Even prescription drugs can have side effects that make operating a truck dangerous. Reckless Driving If a truck driver is speeding or making dangerous choices, there is an increased risk of an accident. Road Conditions Icy roads, windy conditions, or heavy rains can make driving a semi-truck difficult and dangerous.
