Safety goods for driving on snowy roads just in case

When driving on snowy roads, it is a good idea to have the following items on hand in case you get stranded.
(1) Items that keep you warm, such as winter clothes, warmers, and blankets
Be prepared for the temperature inside your car to drop when the heating shuts off.
(2) Drinking water, emergency food, mobile battery, portable toilet, flashlight
Be prepared to spend a long time in your car and be prepared for trouble at night.
(3) Booster cable, tow rope, tire chain
It would also be a good idea to have a booster cable to use when the battery dies and a tow rope to help you escape if you are unable to start. Tire chains are also helpful in dealing with heavy snowfall that cannot be handled with studless tires alone.
(4) Work gloves, rubber gloves, boots, shovel
Make sure you have something ready to remove snow. If the muffler becomes buried in snow, exhaust gases may flow back into the vehicle and cause carbon monoxide poisoning.

When driving on snowy roads, be sure to have items in your car that will come in handy in case of an emergency. Additionally, make sure you have enough fuel before heading out. However, please check the weather and traffic information, and if heavy snow or blizzard is expected, consider changing your plans for going out or changing your means of transportation.
