Big rigs and semi-trucks are the giants of America's roadways, since most vehicles on the road are still no bigger than passenger cars. There are special requirements for truck drivers to operate these vehicles and avoid big truck accidents, just as there are for smaller vehicles. Let's face it, a minor miscue in the presence of a passenger vehicle can become a major tragedy when a big rig is involved. It is estimated that 75% of all big truck accidents are caused by smaller vehicles, and some of those mistakes include changing lanes too quickly, merging in front of a truck improperly, passing without observing appropriate safety measures, and much more. It takes a truck nearly twice as long as a passenger vehicle to stop when traveling at 65 miles per hour. Most cars don't realize this and may be at least partially at fault for a big truck accident. An experienced truck accident attorney can help you discover if you have a claim for any injuries or damages.
