CHiP Officers Drive Trucks

In Volunteers,Ponch and Jon escort a convoy of trucks carrying hazardous chlorine gas.

Jon arrives to meet up with Ponch before they head to work. Jon is surprised that Ponch is already there. Over the radio we hear that a robbery suspect is being chased. Ponch and Jon join in the chase along with Officer Jane Turner. The car being chased, a stolen yellow T-Bird, crashes and bursts into flames at the Newhall Chemical Depot. Fearing that their tanker trucks might explode, drivers scurry to move their trucks filled with hazardous chlorine gas, away from the burning car, which then explodes.

Getraer asks for volunteers but then assigns Ponch, Jon, and Turner to escort detail. The owner of the trucking company, Charley Davis, is informed that the trucks need to be moved to Owens Valley Depot. Charley is upset that they will have to drive their loads 140 miles in the heat of the day.

Ponch and Jon return to the scene of the accident and Charley insists that they get back on the road. The convoy begins their trek again via an alternate route. The police chief and the city councilman inform Ponch and Jon that they are not going to allow trucks filled with poison through their town.They plead with them to allow them through; the councilman gives in and the convoy continues on.The convoy next encounters road hazards including dirt and rocks that force them to stop. While stopped, a rock falls and damages a valve on Robbie's truck causing chlorine gas to leak. She tries to close the valve but is overcome by the gas; she needs oxygen or she will suffocate. Some hikers arrive and mention that they have oxygen back at their campground. Ponch rides over rough terrain and returns with the oxygen and a flat tire. Turner takes Robbie ahead to meet a helicopter transport that has been radioed for. The convoy needs a driver for her truck; Jon volunteers to drive.

While driving the truck, Jon's trailer comes loose after he drives over a rock. Ponch, who is riding Jon's motorcycle, pulls over and boards the truck while it is still moving. In daring fashion, Ponch re-engages the safety after Charley successfully bumps the trailer back into the fifth wheel with his truck. The convoy arrives successfully.

The episode was enjoyable due suspense it provided.Also,check it out how Jon and Ponch drive trucks instead of motorcycles.
