This is video of the collision between a big rig and a tree that blocked a street on Vista for several hours Monday morning.
A big rig rolled down a Vista street and jackknifed into a tree, blocking a four-lane road for more than four hours.
Workers used two tow trucks to remove the tractor trailer along Business Park Drive Monday.
Law enforcement authorities received the first call about the collision just before 6 a.m.
A witness said it appeared the truck’s brakes had failed sending the big rig down the hill and into a hydrant and a tree.
Deputies along with CHP and Vista Firefighters worked on traffic control.
Authorities are still investigating the cause.
