When Patrolman Kathy Mulligan shows up at the CHP Headquarters. She doesn't have a name plate on her uniform like the rest of the cast does. This has happened with different guest stars in different episodes as well.
In the opening sequence Ponch is knocked out running in to cardboard boxes. Jon radios "Roll 11-41 11-42 Harbor Lane and Commerce" 11-41 means "Ambulance needed" and 11-42 means "No ambulance needed"

When Jon and his temporary partner chase the suspect to the Los Angeles Memorial Coliseum, they make an elementary mistake that leads to the suspect's escape.
There are only two ways for vehicles as large as motorcycles to be ridden into and out of the Coliseum: the lower-level tunnel on the west side (through which Jon and his partner follow the suspect) and the arches on the east side (the peristyle end). Instead of both following the suspect into the Coliseum, one officer should have driven around the structure to the peristyle end. By following the suspect, they have allowed him to escape because their motorcycles cannot climb stairs like a motocross bike.

During two chase scenes that begin in Downtown Los Angeles, the police dispatcher says that the suspect is traveling west on Main Street. Although very few of Downtown L.A.'s streets follow the cardinal directions (the entire grid is set at an angle), it is generally accepted that Main Street runs north and south.
