Two men have been arrested and £10,000 of cash seized after their car was seen travelling at up to 100mph on the M6 near Lancaster.
A 34-year-old man was arrested on suspicion of money laundering and has been bailed until June 5.
A 29-year-old man was arrested on suspicion of money laundering and was then further detained by Border Force in relation to immigration offences.
The vehicle was stopped and searched by police at Charnock Richard services at around 2.30pm on Friday and the money was found in the vehicle.
The car was also seized as it was being driven without insurance or a driving licence.
Money laundering is the concealment of the origins of illegally obtained money.
A police spokesperson said: "We take the safety of road users seriously and are determined to disrupt anybody who uses our road network to carry out criminality."
