Police were called to the scene on the A642 - which is the main Wakefield to Rothwell route - just before 2030 GMT on Thursday.
In Lancashire, the dome came off the Darwen Tower and about 40 weather-related incidents were reported to the fire service.
Lancashire Fire and Rescue Service spokesman John Taylor said: "In this age of renewable energy, we had a wind turbine on a farm at Scarisbrick that got a bit too enthusiastic, and got out of control.
"Our fire control section... were in touch with the manufacturers to give us some pretty detailed technical advice as to how to contain that out-of-control windmill.
"The risk is... that something will break loose and obviously hit somebody or a passing vehicle and cause a worse accident, so it's a case of ensuring that doesn't happen."
The dome from the Darwen Tower on Beacon Hill was blown off.
One Darwen resident, who gave her name as Eileen, told BBC Radio Lancashire: "My son opened the curtains, I mean we look at Darwen Tower every morning, and the dome's disappeared - it must have been blown off."
