Two people who were injured in a three-car crash that partially blocked the A47 at Hockering did not require hospital treatment.
Police were called to the collision between two Volkswagens and an Audi, which happened west-bound near the Mattishall Lane junction, at 1.55pm.
A police spokesman said one person suffered a bump on the head and another complained of whiplash.
A spokesman for the ambulance service, which arrived at the scene at 2.11pm, confirmed this information.
The service sent one rapid response vehicle, which was cleared to leave the scene at 2.19pm.
Police said the crash had blocked the road, and had advised drivers to approach the area with caution.
It was the latest in a series of accidents in the A47 in the Hockering area that have prompted wide-spread calls for government action to improve road safety.
