Poor vehicle maintenance, negligent or inexperienced driving, and hazardous road or weather conditions can all lead to accidents involving commercial trucks. Some specific risks include driver fatigue; speeding; overloaded, unsecured loads; unfamiliar or difficult routes; potholes; lack of shoulders; snow, ice, rain, or fog; inadequate training; and congested construction zones. Being unaware of or unprepared for any of these issues can cause truck drivers to lose control and potentially cause disastrous consequences.
