Are truck accidents on the rise? It is estimated that there are currently more than 2 million 18-wheelers on the highways in this country. Each rig can weigh as much as 80,000 pounds. All those trucks on the road can pose a serious risk to motorists. According to NHTSA and the DOT, large trucks accounted for almost 4,000 fatalities in 2013 alone. Large trucks are involved in multiple vehicle fatality crashes at twice the rate of passenger vehicles which accounts for almost one out of every four passenger vehicle fatalities according to the Advocates for Auto and Highway Safety.
