I wonder if he was just following traffic, letting the vehicles ahead be his eyes? I didn't see anyone in front of him, but I suspect many do just that in inclement weather, just watch the vehicle in front of you, and hope for the best.
Just looked again, and it looks like he was hit by the SUV, and this caused him to swerve. Look at the six second mark, and slow down the playback.
The truck driver, being a professional, should know that he can't stop as quickly as a car and that it would be dangerous for him to use the leading car's brake lights for a braking signal.
He needs to drive his own rig.
