A spokesperson from the Staffordshire police said Tamou was struck by a Toyota on the M6 last Thursday at 10pm local time.
They said Tamou’s truck had broken down and he was out of the vehicle. The road was closed for more than 15 hours after the crash, BBC reported. Tamou died at the scene.
The 22-year-old Toyota driver suffered leg and facial injuries and had been arrested on suspicion of causing death by dangerous driving.
The Staffordshire police department said Tamou was a “devoted husband, father to six children and five grandchildren”.
“He was a lorry driver for many years and loved playing, refereeing and coaching rugby.”
“The loss of Cliff will leave a mark on players, coaches, clubs, officials and societies across Rugby League.”
Other rugby clubs he was associated with, including the Ashton Bears and the Haugesund Sea Eagles said they were “saddened to hear the heartbreaking news”.
They both said Tamou was heavily involved in women’s rugby and was a major advocate was gender equality in the game.
“His help and support, in particular to our younger teams and girls' teams, with his calming manner and coaching conversation during the game will never be forgotten.
