Five Car lengths, but only if you are on your toes. It depends on how alert you are at the time and if you can see and monitor the tail lights of the chain gang a lot further ahead than the car in front of you. If you are behind a car and it hits a stopped dump truck - can you stop? If you are tired - give yourself a lot of stopping room.

Actually, 9 car lengths if using 2-second rule. If follow 3-second rule, you should keep 13 car length.
