The M25 had to be closed in both directions between junctions five and six after a horse tried to escape from its trailer while in transit.
Twelve Kent Fire and Rescue officers and a vet arrived to find the horse trapped in the door of its horse box following a call from motorway control.
The animal was sedated and moved to a field near Clackett Lane Services using low pressure airbags.
Motorists using the M25 faced long delays following the incident.
