Zip Zap Monster Truck ?
 

Hi! Today when I got done useing my Chevy Monster truck, when I turned the power off on my remote control the truck keep on moving alittle until I shut off the switch on the truck. What would cause the truck to move while the remote is turned off?? Take Care! Paul

While playing around with the PCB, i noticed that sometimes some wires can come off and come in contact with other parts of the circuit. So, check for lose wires and it may sound stupid but was the truck on a flat surface because if the truck was on a little slope it may have just kept on rolling down when your remote was turned off.

Hope this helps

so interference nearby maybe. maybe ur nieghbor was using the same frequnce on an rc car too.

Was it a 27 mhz truck?

I've had em, do that when the internal battery is almost dead. I think it's just the RX switching off or acting erratically when the power gets to low.
