Doris Mary Finch-West, 59, of Rushy Drove, Donington, died in a collision involving three cars near Gosberton on Sunday.
Tomorrow (Thursday) would have been her pearl wedding anniversary.
Husband Richard, 61, said: "She was the greatest. She was a very good mother, and a very good wife."
A housewife, she had three children, Terri, Michelle, and Daren.
The drivers of the three cars were all from Donington, and Mrs Finch was a passenger in a Vauxhall Vectra driven by 37-year-old son Daren.
The Vauxhall was involved in a collision with a Ford Ka being driven by a 19-year-old woman, and a Toyota Yaris driven by a 50-year-old woman, in Belnie Lane just before 3pm.
Mrs Finch-West was pronounced dead at the scene. The drivers received minor injuries.
A Lincolnshire Road Safety Partnership spokesman said conditions at the time were 'extremely wet'.
Mrs Finch-West becomes the 39th person to die on the roads of Lincolnshire this year, compared to 78 at the same time last year.
Police are appealing for witnesses to the crash.
