HOUSTON, Texas (KTRK) -- Eleven vehicles were involved in a wreck with an 18-wheeler Monday morning on I-45 northbound at Mt. Houston Road.

According to other drivers involved, there was an earlier two-car crash, and that's why people on the road were stopping.

The 18-wheeler driver told ABC13 he did not fall asleep. He says he just couldn't stop fast enough when someone cut him off.
