A ROOKIE motorist made the mistake of overtaking an unmarked police car - at 131mph.

Once officers caught up with the offender in the early hours of this morning (Monday), they were stopped.

The car was being driven on the M5 northbound.

The driver only passed their test a year ago.

"Stopped, driver only had their licence for 1 yr!
