A driver caught speeding at 110mph on the A1 told police it was because he “needed the toilet, a number two”.
A silver Mercedes was stopped by an unmarked police car near Yaxley in Cambridgeshire.
It was seen speeding and undertaking in “awful” weather conditions.
An officer from the Beds, Cambs and Herts Roads Policing Unit wrote on Twitter: “The ‘professional’ HGV driver was very sorry but he ‘needed the toilet, a number two’. Err that’s okay then. Reported.”
Drivers caught speeding in excess of 100mph face disqualification from the road rather than penalty points but the decision is at the discretion of the court.
