For some, the wonder of making snowmen and having snowball fights wears thin, and they turn to more adventurous winter activities, like snowmobiling.

To help you prepare for your gas-powered trip across the snow-covered wilderness, we've compiled a list of nine safety tips recommended by the International Snowmobile Manufacturers Association and the American Council of Snowmobile Associations.

• Know the law. Laws and regulations for snowmobiling vary from state-to-state, with some states requiring registration, trail permits and/or wearing helmets. Some, but not all, states permit riding on roads or in the ditches next to them. Make sure you know and obey the laws wherever you ride.

• Don't drink and drive. In addition to being illegal in many states and Canadian provinces, drinking alcohol while snowmobiling is simply a bad idea. Alcohol consumption slows your reaction time, hampers your ability to make good decisions, and increases your risk of hypothermia. It is a combination that can quickly turn a challenging and exhilarating sport into a recipe for disaster.

• Always dress appropriately. Always wear a safety-certified helmet, even when it is not required by law, and preferably one with a visor to help you see while driving. Also, wear layers of clothing, including a windproof outer layer so that you can easily adjust to changing weather conditions.

• Take care of your snowmobile. Before each ride make sure that you follow the "pre-operation" checklist in your owner's manual, and make sure you always keep your snowmobile in good repair. Nothing can ruin an outing faster than mechanical problems, especially when you know it could have been prevented.

• Be prepared. Despite your best efforts, accidents and breakdowns will happen. But simply planning ahead has averted many a crisis. When you go out for a ride, always bring a first-aid kit and a few survival items, such as a flashlight, compass, fire starting kit, and some high-energy food. Also, bring a small but useful tool kit and a few spare parts on all of your trips.

• Bring a friend. Don't snowmobile alone. Not only is snowmobiling more fun with friends and family, it's safer, too.

• File a plan. Always make sure one of your friends or family members knows where you're going and the time you expect to arrive. "Snow plans" like this can prove invaluable for searchers in case you get lost or hurt on your ride.

• Be aware of the conditions. Snowmobiling in the dark, over frozen rivers and lakes, and in the mountains all require extra care. Make sure you know of any additional problems you might encounter while riding in these conditions and how to avoid them.

• Be courteous and careful. Always make sure that you signal your intentions to other snowmobilers and any other drivers around you. Be especially careful crossing streets. If a road is suitable for snowmobiling, cars may have difficulty slowing or stopping.
