The scene where Carrie (Frog) announces her ending up the relationship to Bandit was written by Sally Field, who was about to break up with Burt Reynolds at the time. Reynolds wanted Sally to express her feelings about the breakup on film because he wanted to know how she really felt about him.
The world record for the longest stunt car jump by a car powered with its own engine, at 163 feet, was performed for the film. Stuntman Gary Davis jumped a 1974 Dodge Monaco car for the roundup sequence in this movie. Davis unfortunately was injured during the stunt, receiving a compressed vertebra from a hard landing.
The roller coaster destroyed in the movie is the old "Greyhound" coaster that was located at the Lakewood Fairgrounds in Atlanta, Georgia. It was due to be torn down and rebuilt after being deemed in unsafe condition so its destruction was written into this movie. It was also shown in the background during the first Smokey and the Bandit (1977) movie.
This movie's storyline features an elephant mammal. About a year after this film was released, another cross-country American road comedy featured large mammals as well. That movie was Honky Tonk Freeway (1981) and the mammals, a rhinoceros and a water-skiing elephant. Both pictures were filmed in Florida.
Many brand new Pontiac Le Mans sedan cars decked out as police cars were seen during the roundup sequence. A Phoenix car agency declined to deliver the vehicles when it was made aware that they did not include air conditioning. Pontiac recalled the cars and later supplied the production with the cars.
The name / word "Smokey' is C.B. Radio slang for any member of Law Enforcement. It is derived from the wide use by many Highway Patrol Officers who wear wide brimmed hats that are identical to the one worn by "Only you can Prevent Forest Fires" mascot "Smokey the Bear"...

The trivia item below may give away important plot points.
The pregnant elephant that Bandit & Cledus were trying to deliver from Miami to Dallas finally gives birth at Lion Country Safari wildlife refuge. Although those scenes were filmed at the LCS near West Palm Beach, Florida, there was another LCS refuge opened at the time in Grand Prairie, Texas (near Dallas) at the time of this movie's production (1980). The LCS in Grand Prairie opened in 1971 and operated for 21 years. It was ultimately closed down in 1992 due to constant flooding from its proximity to the Trinity River.
