The collision caused the truck to catch fire and send debris over the median wall, striking at least one other vehicle on the southbound side.

Marika Meeks and her husband were running errands when they saw the fiery aftermath.

"All of a sudden we saw a bunch of smoke," Meeks said.

They saw both vehicles up in flames.

"My husband goes, 'I think there's a motorcycle underneath that,'" said Meeks.

She shot cellphone video of the fire.

"It shakes me up because I think about how vulnerable all the people you have in your life and care about, how quickly they can be gone," Meeks said.

DPS said the rider had his hazard lights on when the truck driver slammed into him.

"We don't know if he was actually on the motorcycle at this point or standing next to his bike but it caused the rider to go over the top of the wall and into southbound lanes," said Trooper Kameron Lee with DPS.

Northbound Loop 101 was closed at 90th Street until approximately 1 p.m.

The southbound Loop 101 was reopened at Shea Boulevard at approximately noon.
