A Lyndon man was cited Thursday for driving too slow on I-91.

At about 2 pm, troopers patrolling I-91 north of St. Johnsbury saw a vehicle traveling in a negligent manner at an excessively slow rate of speed. Using an in-car radar system, troopers determined the passing vehicle was traveling at nearly half the posted speed limit, which was causing a traffic hazard to northbound motorists. Troopers subsequently conducted a U-turn and followed the suspect vehicle northbound on I-91.

Once directly behind the vehicle, troopers observed the motorist fail to maintain their lane of travel and slow down and speed up without cause or reason. A traffic stop of Lee Lavoie (76) of Lyndon revealed several indicators of impairment. Lavoie had a criminally suspended license and was wanted on an outstanding warrant for the charges of DUI #3 and Operating on a Criminally Suspended License.
