1. Slow Down
You're no dummy, so you know that it's smart to reduce speed when traction is reduced, as it is when you roll off road. There's a surprising amount of grip on hard-packed dirt roads, but even so you need to be gentle with your inputs. Keep in mind it's much easier for wet, sandy, or otherwise slippery patches to hide on dirt or gravel. Slowing down reduces the risk of sliding and allows more time to respond calmly without the need for last-second maneuvers that can put you on your head.
