During the first incident, a Dodge pickup truck and a Buick crashed into each other around 3 a.m. Monday on Airline and Gulf Bank, the Harris County Sheriff's Office said.
Both drivers took off.
A deputy saw what happened and chased the truck driver, who kept going until she crashed into a Nissan Maxima and left the scene again.
One person in the Nissan was taken to the hospital with non-life-threatening injuries.
The truck ended up crashing at Gulf Bank and the North Freeway, slamming into a power pole. The pole snapped at the base, causing power lines to land into a tree and catch on fire.
The driver ran off again, but was eventually found and brought back to the scene. She was arrested.
She did have two passengers, an adult and a teenager, who were both injured and taken to the hospital.
The Buick's driver was also eventually caught.
