HOWLAND, Maine — A boulder most likely kept an Enfield man from plunging into the Penobscot River on Saturday afternoon when his car went off Route 6 and over a guardrail.

Shane Enos, 26, was driving east when something on his 1991 Chrysler LeBaron malfunctioned about 2 p.m., according to Maine State Trooper Lawrence Anderson. The car went down the embankment toward the river but was stopped about 20 feet from the water when the undercarriage became stuck on the boulder.

Enos was not injured but his car was demolished, Anderson said.

The trooper issued him a ticket for not having proof of insurance.

Anderson said speed might have been a factor in the area where the speed limit is 35 miles per hour.
