One man died in a single-car accident Tuesday morning when the vehicle drifted off the road and hit a tree.

Peter Webber, 55, of Sanford, died after his 1999 Pontiac Sunfire sedan left the road near the 1400 block of Littlefield Road in Wells and hit a tree, rolling back onto the roadway on its roof.

Webber had been driving east at the time of the accident. The posted speed limit on that section of Littlefield Road is 45 mph.

Wells police, fire and emergency medical services responded but were unable to save Webber. The road was closed for over two hours.

The cause of the accident is under investigation.
