Three ferry staff members had a lucky escape when the kiosk they were working in was flattened by a passing HGV.
Passengers and other staff members rushed to help when the lorry struck the kiosk at Town Quay in Southampton shortly before 13:00 BST.
Red Funnel said three staff members were inside at the time. One woman was taken to hospital with minor injuries.
It warned of disruption to road traffic and sailings to and from the Isle of Wight.
The crash was captured on a webcam located in a nearby building.
It showed other staff members and members of the public running towards the kiosk when it was demolished by the lorry, which was apparently attempting to park.
A Red Funnel statement said: "Three Red Funnel colleagues were inside a check in kiosk which was struck by a HGV this afternoon.
"Our priority is the safety of our team members and passengers, and although there are no significant injuries, both police and ambulance services are in attendance as a precaution.
"The incident area has now been secured and we are currently operating a shuttle service to clear traffic as quickly as possible."
South Central Ambulance Service said three people were treated at the scene for non-life threatening injuries, with one then taken to hospital for further treatment.
Hampshire Constabulary said no arrests had been made.
