Officers are appealing for information following a road incident in the Ellingham area.
Norfolk Constabulary received a call from a member of the public at around 7.20am on Monday who reported seeing a car swerving along the A143.
The driver, a woman in her 40s, was stopped by officers a short time later just outside Billingford and has subsequently been reported for careless driving.
Officers would like to hear from anyone who believes they may have seen the silver Vauxhall Zafira being driven along the road towards Diss.
Witnesses are asked to contact PC Pete Partridge at Norfolk Constabulary on 101 or Crimestoppers anonymously on 0800 555 111.
