Charlotte Brannan, 44, was stopped on the motorway near Gildersome as part of a two-year investigation into the drug operation by police.
During investigations, the Organised Crime Unit had found that Brannan and her partner Mark Davey, 53, had control over a substantial amount of cocaine and heroin across Yorkshire.
When searching Brannan's car in May 2018, officers found one kilogram of high purity cocaine in the foot well of the car.
Her house on Hartshead Lane, Cleckheaton was then searched.
Officers found one kilogram of heroin and more than £26,000 in cash.
It is believed that when Brannan was stopped she had been on her way to meet Robert Clark, 29, in Scarborough.
Clark was arrested at his home on Loders Green where more than £160,000 cash was found.
In July 2018, Davey and Michael Wilson, 36, arranged to deliver 1kg of vacuum packed cannabis skunk to Shaun Smith, 38, who had travelled from Hull.
Smith collected the cannabis and was spotted by police, who attempted to stop the car he was travelling in.
Smith evaded officers by driving the wrong way up the M62 slip road at the Chain Bar roundabout.
He nearly hit a motorcyclist head on during the chase.
Officers found vacuum packed cannabis skunk concealed in a grass verge at the side of the motorway.
The car was found abandoned at Hartshead Moor services.
He was then caught on CCTV at a taxi rank arranging with Davey to take a taxi back to Hull.
Nine members of the gang were jailed at Leeds Crown Court on Tuesday, February 4.

Detective Chief Inspector Mark Walker, from West Yorkshire Police’s Precision Serious and Organised Crime Unit, said: “This was a substantial operation, conducted in collaboration with our neighbouring Police Forces, which has resulted in nine people being jailed for a significant period.
“The harm caused to individuals and communities as a result of drug dealing cannot be overstated.
"This is not a victimless crime and it is a priority for West Yorkshire Police in support of Programme Precision - the National strategy to tackle Serious Organised Crime.
“I hope the significant prison sentences they have received will serve to reassure communities in West Yorkshire, and further afield, of how seriously the police take the issue of drugs.
"It should also send a clear message to those who think they can get away with drug dealing, that they will not get away with profiting from this criminal trade.”
