49 year old Matt Barker was in a collision on the slip road near junction 3 in January last year.
He was driving his transit van when he crashed into the rear of a Peugeot, shunting it into the rear of a lorry.
He then fled the scene but was successfully tracked down to nearby woodland by a police dog.
Barker pleaded guilty to three offences and was sentenced to four months in prison, suspended for two years.
