POLICE are trying to trace a lorry driver who failed to stop after a van forced to swerve ploughed into a road sign and was badly damaged.

Officers are appealing for witnesses to the collision on the M5 this week.

The incident happened between junctions 24 (North Petherton) and 23 (Bridgwater) northbound on Tuesday (January 5) at around 5.40am.

An Avon and Somerset Police spokesman said: "The driver of a white Ford Transit van was forced to swerve to avoid a dark coloured HGV, and collided with a road sign in the central reservation, causing extensive damage to the sign and vehicle.

"The driver was uninjured.

"The driver of the HGV failed to stop following the incident and we’re keen to identify them."

Police would like to hear from anyone who saw what happened or noticed an HGV being driven erratically around the time of the incident.

They are particularly keen for anyone with dashcam footage to come forward.

If you can help, call 101 quoting log 0103 of January 5.
