The point of contact where the tires meet the road can greatly impact safety and driving circumstances.
Driving on dirt and gravel roads is significantly different than paved roads. Reduce speed, drive in the middle of the road (when there is no approaching traffic), keep distance between you and any vehicles ahead are good rules to keep in mind.
Always be aware of potholes on both paved and dirt roads. Not only can they damage your vehicle, they can cause it to lurch or momentarily lose control – especially at higher speeds. Similarly, speed bumps and rumble strips should be approached with the same caution.
