Trail Etiquette
ALWAYS One of the most common and most commonly broken rules on any trail ride is to always keep the vehicle that is behind you in your rear view mirror. In this way, the group will always be together -- if the person behind you slows down, you should slow down, and this will cause a chain reaction to the whole group. This is especially important at trail intersections. If you lose sight of the vehicle in front of you, let the driver know to slow down -- another great reason to have a CB. This in turn will work its way up to the trail leader and no one will get lost. Do not follow too closely either, especially while going downhill. When you make it up over an obstacle, you need to wait for the next vehicle in line to make it, so if a strap is needed you can assist. If those below you can't see over the top of an obstacle, let them know when it's clear at the top.
