Revealing mistake: On the way to the party, near the end, they are supposed to be in Alabama when the car gets pulled over, but the officer's badge, shoulder patch, and car all say Georgia State Police.
Factual error: When they are at the Cadillac dealership, taking delivery on a car in 1956, the American flag in the background is incorrect. It should have been a 48 star flag, not a 50 star flag.
Deliberate mistake: During the ice storm, Hoke brings Miss Daisy coffee because he figured her stove was out. A few scenes before that they are frying chicken on a gas stove. Gas doesn't go out during power outages.
Continuity mistake: During the car accident Miss Daisy is wearing a beige dress. Later she looks out of the window at the towing activities and is wearing a red dress. When Boolie argues with her about her driving she is wearing a green dress. This is happening within too short a time to explain all this unnecessary changing.
Other mistake: In the scene where Miss Daisy asks Hoke if he has had the air conditioning checked, the car they are in doesn't have air conditioning, as there are no clear tubes that transition the airflow from the rear package shelf to the ceiling vents that aren't there.
Continuity mistake: In the reversing accident the car goes down a nearly vertical slope, but all close-up shots taken through the front window show that the car's position is still nearly horizontal. That's why Miss Daisy can get out without any problem, and that's why, after she has left the car, it falls down the same slope again.
Factual error: As Miss Daisy is walking to the trolley stop to go to the Piggy Wiggly market, one of the houses in the background has modern skylights on it, and both are modern homes from post-1948.
Continuity mistake: In the opening when Boolie is confronting Daisy about her driving accident, he leans on the kitchen doorway with his arms. In the next frame, he is leaning on the doorway with his hands.
Continuity mistake: While Hoke is driving Daisy to her synagogue (the time when they learn that her synagogue has been bombed) they pass a little red brick house with a white picketed fence and a 1964-63 light blue Chevrolet pickup sitting in the driveway. They continue to drive and argue as usual and moments later they pass the same house and truck.
