Tight corner jams driver into barrier. Was this crash preventable?

At 2 a.m., John Doe was northbound on a two-lane highway pulling a flatbed of lumber through a fog-filled, misty rain. Doe reduced his speed to 50 mph from the posted limit of 55 when he noted a “Construction Ahead” sign ahead.

The highway appeared to be devoid of traffic, but it was difficult to know for sure. Both sides of the road were bordered by concrete barriers.

As Doe rounded a blind curve to the left he was suddenly dazzled by high-beam headlights from a truck driver coming in the opposite direction.

Doe quickly realized the other driver was trying to avoid side-swiping the barricades by encroaching onto his side of the roadway. Panic-stopping would cause a jackknife, Doe thought, so he moved to the right onto a narrow shoulder to avoid a collision.

Doe lost control on the mushy surface and grazed a barrier, and banged up his front passenger side.

Was this accident preventable?

The National Safety Council ruled it was preventable. Doe was dealing with nighttime fog on a slick road with a blind curve in a construction zone. Clearly, he was going too fast for conditions.
