LUMBERTON, North Carolina (WTVD) -- The North Carolina Highway Patrol said Wednesday that the driver of the tanker truck that started the deadly chain reaction Tuesday wasn't speeding - but didn't slow down fast enough.
That leaves questions, of course, about why. And whether anything might have been different had the road been wider than two lanes.
Despite the fact we know how the crash started and roughly how it happened, we don't know why the driver of that tanker, 68-year-old Mike Bricker, didn't slow down.
Bricker was one of five people killed in the crash.

His company, Blue Mountain Transport, which is based in Mount Airy, said little. But speaking to the ABC11 I-Team by phone, they told us they have no idea what happened.
"It's a tough time right now," a company official said. "We don't know what happened out there, and we don't expect to find out."

The crash shut down both directions of I-95 for almost 12 hours near Exit 10 in Robeson County.
It could take weeks or even months for state investigators to piece together all the details.
