Police, fire and ambulance services were all called this afternoon to deal with a two-vehicle collision at the Washington roundabout.
The A283 westbound was shut for an hour and a half while the scene was being cleared.
Nobody was injured in the collision, according to the Storrington branch of West Sussex Fire and Rescue Service.
Police later confirmed a man has been reported for driving without due care and attention in connection with the incident.
He will be issued with a summons and will have to attend court, a Sussex Police spokesman said.
