A three-car pile-up closed a major South East Cornwall road for more than an hour.
Several people were taken to hospital following the crash on the A38 near Liskeard, said police.
A force spokesman said the collision had involved a silver Honda Jazz, a green Nissan Micra and a white Fiat Punto.
The smash happened at around 8pm on Tuesday outside the Trago Mills superstore.
The road was closed in both directions until around 9.30pm as emergency services worked at the scene.
The police spokesman said nobody had suffered serious injuries in the incident, though several people required hospital treatment.
