HOUSTON -

Traffic piled up on the North Freeway after one crash triggered nearly a dozen others.

It all started Friday around 11:45 p.m. when a driver crashed near the Cypresswood Drive entrance southbound ramp.

Police said the man was taken to the hospital in stable condition.

The scene was clearing around 12:15 a.m. when an orange Camaro stalled on the entrance ramp.

The driver got out and started pushing the car to get it off the ramp.

That is when police said a maroon colored car with two occupants came up the ramp, apparently did not see the man pushing his car and slammed into the back end, hitting the man. 

The driver pushing his car was taken to the hospital in serious but stable condition, and the driver of the maroon car was taken to the hospital in stable condition. 

The Spring Fire Department responded to reports of the second accident and parked on the shoulder of the freeway with emergency lights on.

Around 12:30 a.m., police said a drunk driver in a small pickup truck came speeding down the freeway and hit the back end of the Dodge Charger belonging to the Spring fire chief, and then hit the ambulance.

Then around 12:45 a.m. police say a woman driving in the lane next to the ambulance accident stopped to look at the scene.

That caused the driver behind her to slam into the back end of her car. 

No one was injured in that accident.

The last accident happened around 2 a.m when deputies blocked all but one lane.

A car struck the back end of an SUV, but it was a minor accident and was quickly moved.

A total of three people were taken to the hospital out of the five accidents.

The freeway was closed for several hours.
