“Our message to the trucking industry is clear. Immediately find a way to better regulate, supervise and train your drivers or we will take the steps through Congress and our state legislature to force such actions so that needless deaths such as to my brother will never happen again,” said his sister Regina.

Attorney Robert Allard is representing the family.

“This gut-wrenching tragedy would have never happened had the responsible companies taken steps to ensure that an unskilled trucker driving a faulty big rig not be allowed to traverse a complicated, mountainous journey,” Allard said.
