Lindsay Lohan headed straight back to work after being involved in a car accident.

The actress was released from hospital on the same afternoon she was admitted, after her vehicle plough into the back of an 18-wheel truck.

A representative says she was brought to Santa Monica UCLA hospital only as a precaution and she had no serious injuries. Lindsay's assistant - who was traveling in the passenger seats and went to hospital separately from the star - also has been declared physically fine.

The website reports that she headed directly from the ward to her original destination following her check up.

The troubled actress was driving her black Porsche on the Pacific Coast Highway when it hit a large vehicle. According to TMZ.com, the rear bumper was taken off the car and the passenger window was smashed.
