Here are a few simple rules from the Motorcycle Safety Foundation you should follow when you anticipate coping with sand, mud, water or any loose surface or obstruction in the road:

• Downshift and slow before you reach the problem area.
• If there is traffic in the area, make sure that the drivers are aware you are slowing.
• Try to cross the bad surface in a straight line, or at least do not change direction or speed abruptly.
• Stay read to maintain the balance of the motorcycle.
• If you are moving along and have to go over an obstruction that is lying across the road, like a 2x4 piece of wood, rise upon the foot pegs and shift your weight toward the back of the saddle as your front wheel comes up to the obstacle. This will make it easier for the front wheel to bounce up and over. Then move your weight forward to help your rear wheel go over.
• Do not accelerate until you bike is completely over the obstacle.
