A tractor towing a trailer carrying hay bales caused traffic chaos this morning after the trailer overturned on London Road in Tring.
Police closed the roundabout at the junction with the A41 and the A4251 just after 10.15am while they cleared the hay from the road.
The delay caused tailbacks into the town centre.
Herts Constabulary spokesman Sarah Spence confirmed that paramedics were also on the scene. She said: “Thankfully no one was injured, but we informed highways as there was damage to a street light at the roadside.”
A spokesperson from the East of England Ambulance service confirmed paramedics were called to the scene just after 10am but no one was treated for injuries.
The road was reopened by 11am and traffic is now flowing freely.
