A 29-year-old Suffolk man faces a court summons after police clocked a BMW travelling at 110mph along the A14 between Felixstowe and Ipswich.
An officer from Norfolk and Suffolk Roads and Armed Policing Team recorded a vehicle exceeding the speed limit by 40mph last Sunday evening.
The team later published a photograph of the speed gun reading on the @NSRAPT Twitter account, commenting: "I have no words for this one".
A police spokeswoman said the incident took place on the westbound carriageway of the A14, near Trimley St Martin, at 6.40pm on Sunday, May 2.
"The driver of a BMW 325 car, a 29-year-old man from Stowmarket, was issued with a TOR (traffic offence report) for exceeding speed limit, recorded at 110 mph," they added.
"A summons will be sent in due course for a future court appearance."
