I was traveling south bound on the highway going toward the pet store (the destination i wanted to go to). i slowed down with the flow of traffic, i dont recall whether there was a light that was changing or not . like i said i did slow down and apply my brakes, and that is when i felt something wrong. my vehicle did a jerk which caused me to go in an off handed direction and trying to correct this i swerved to straighten up my vehicle, and it did not work out , i went towards the middle median of the highway road.... i knew i was going to hit the poles in the median. that is the last thing i remember seeining. the police record will show i went head on with a tractor trailer. my main concern about this whole accident was i felt something happened or went wrong with my car which caused me to loose control of my vehicle. (ex. brakes locking up....) i need this incident investigated.
