Estrada played highway patrol officer Frank Poncherello aka Ponch. His partner throughout much of the series was Jon Baker, played by actor Larry Wilcox.
The show ran for 139 episodes over six seasons, from 1977 to 1983.
"CHiPs" stands for California Highway Patrol. The show was set in sunny southern California, with much of the exterior filming taking place in and around Los Angeles.
Robert Pine plays the former naval officer and current CHiPs Sgt. Joe Getraer, who must muster all of his leadership skills to get the freewheeling Ponch to toe the line. While Getraer mostly sticks to the station, he will sometimes fill in for an injured officer or hit the streets for an important case.
Jon and Ponch never once draw their guns throughout the entire run of the family friendly police series. The only cast member to draw his service weapon is Officer Barry "Bear" Baricza.
When Erik Estrada walked off the set during a contract dispute in Season 5, producers hired Olympian Bruce Jenner to replace him. Jenner played Officer Steve McLeish in half a dozen episodes of the series.

Ponch is tasked with training the CHP's first female motorcycle officer Melanie Mitchell, played by actress Trisha Townsend. While he's frustrated by the job at first, he ends up falling for her by the end of the episode.
It's Sgt. Getraer who nearly loses an eye in the Season 4 finale. While he's in the hospital recovering, the poor patient next to him winds up murdered.

Erik Estrada always wanted to be a cop after he finished acting. He was deputized by the police force in Muncie, Indiana in 2006, and then moved on to work as an officer in Virginia.
They were the ultimate team on "CHiPs," but the two actors never got along in real life. It got so bad that Wilcox refused to invite Estrada to his wedding, which took place while the show was still on the air.
Despite not knowing how to ride a motorcycle when the show premiered, Estrada insisted on doing his own stunts. The choice came back to bite him in 1979, when he crashed his bike on set and broke eight ribs. Producers wrote his injury into the show.
"CHiPs 1999" premiered on TV in 1998 and featured a look at the force 15 years after the original series ended.
Officer Bruce Nelson was injured in the movie when he crashed his bike into a parked car. The cops would later learn that a gang of thieves they were chasing was responsible for the accident.
The gangs of thieves in the film used smoke bombs to distract motorists, who would pull over to check their vehicles. With the motorists distracted, it was easy for the thieves to nab their cars.
Dax Shepard not only took on the writing and directing role, but also plans to play Officer Jon Baker, with Michael Pena as Ponch in the 2017 release.
The Season 5 finale was actually a pilot dedicated to an elite squad of martial arts experts on the LAPD, with Fred Dryer as the leader of the ninja cop squad. Due to low ratings, the pilot was never picked up.
