While driving south bound on i95 express lane, the vehicle in front of me stopped abruptly. I attempted to break but was unable to do so. Also the emergency breaks/front vehicle collision warning did not activate. In order to avoid a head on collision, I swerved to the right and my front left side made impact to the other vehicle on their right back side. This impact cause my vehicle to spin out of the express lane and into the regular traffic 180 degrees causing me to be facing incoming traffic. The air bags did not deploy- the state trooper, fire safety, and tow truck representative all commented that it should have. After the incident FDOT had to tow my vehicle to the shoulder prior to being towed away. During this time I was not able to turn the engine off- it remained on and was towed with the engine still running. The vehicle is currently under assessment with my insurance provider.
