The pile-up occurred at 4.30pm on the Rangsit-Nakhon Nayok Road in Tambon Bung Yitow, causing a severe four-kilomretre-long traffic jam before the scene was cleared.
The initial police probe found that the woman had traced her husband using GPS, caught up with his white Mercedes Benz at Sawai Pracharat Road and then decided to crash her vehicle into his to stop him from getting way.
The crash also caused damaged three other passing cars.
