18-wheelers can cause an extreme amount of damage when they collide with another vehicle. Commercial truck drivers are subject to multiple state and federal regulations that regular drivers do not have to worry about. Often, 18-wheeler accidents happen because the driver violated one of these regulations. Hours of service violations are far too common, leading to driver fatigue that can increase the likelihood of truck wrecks. You may be able to recover compensation from the driver, the trucking company, or their insurance policy.
