One of the cars ended up on its roof but emergency services confirmed that no one was trapped, and once brought to safety, work was carried out on cleaning the road up after the lorry fuel tank rupture caused a spillage.
One man, the driver of one of the cars, has been taken to Walsall Manor Hospital after being treated at the scene for injuries not believed to be serious.
The closures caused delays of around one hour and over six miles of queues tailing back to Junction 7, as lanes one and two of the four lanes were closed between Junction 9 and Junction 10.
The tailbacks also affected the M5 link to the M6, due to the lane closures.
A spokesperson for West Midlands Ambulance Service said: "A passing ambulance officer came across a collision involving two cars and a lorry on the northbound carriageway of the M6 between junction 9 and 10 at 12.16pm. An ambulance and a paramedic officer were responded to the scene. Crews treated one man, the driver of one of the cars involved, for injuries not believed to be serious before he was conveyed to Walsall Manor Hospital for further checks."
West Midlands Fire Service attended the scene, and Willenhall Fire Station said on Twitter: "Junction 10 northbound slip road closed due to Traffic incident please take care driving past crews working in roadway."
West Midlands Fire Service said in a statement: "At 12.31pm on Tuesday 16 August, West Midlands Fire Service were called to a road traffic collision at junction 10 of the M6.
“Crews from Walsall and Willenhall Fire Stations attended and found a collision between three cars and a lorry. While one of the cars had come to rest on its roof, no one was trapped. One person was checked by West Midlands Ambulance Service on the scene.
“Lanes of the M6 were closed by West Midlands Police and the Highways Agency to allow our crews to work safely. The fuel tank of the lorry had ruptured with fuel spilt on the road, and our crews worked with the Highways Agency to clean this up to make the road safe.
“All lanes have reopened, and we thank drivers on the M6 and the public for their patience while we dealt with the incident.”
