Winter Driving Tips
Driving in the snow is extremely dangerous if you are not careful. Here we provide advice on safe driving in winter and some tips on driving in snowy conditions.
Attaching studless snow tires enables safe driving in Japan.
We recommend equipping your vehicle with studless snow tires during winter in preparation for snowfall. We provide these free of charge in some areas during certain periods.
Clear the snow off the vehicle
Remove the snow from the roof, windshield, windows, and hood of the vehicle. Make sure to also remove the snow from the turn signal lights, tail lights, and headlights. Snow that had accumulated on the roof of the vehicle will slide onto the windshield when you hit the brakes; it will interfere with your view and put you in great danger.
Remove the snow from the soles of your shoes
Normally, you can just get on a car and drive without worrying about anything. However, you need to be cautious if you’re in a snow country. If snow is stuck on the soles of your shoes, not only will the feel of pressing the accelerator, brake, and clutch pedals be different; you may also be in danger if your foot slips off the pedal. Make sure to remove all the snow from the soles of your shoes before getting on the vehicle.
Parking and Stopping
Avoid stopping at the edge of the road
Ditches and gutters on the edge of roads may not be visible due to snow, and there is a risk of the tires slipping into them. Other vehicles may also slip, lose control, and crash into your car. Refrain from stopping on the edge of roads when you need to use your cellphone or pick up or drop off people. If you have no choice but to stop on the edge of the road, then make sure your hazard lights are turned on while the vehicle is stationary.
Do not use the handbrake
When the vehicle is parked for a long period of time in a snowy areas, you may not be able to release the handbrake when it freezes in place. Instead of using the handbrake when parking, place the shift lever in the [P] position for automatic vehicles or in first gear (or reverse gear) for manual vehicles.
Raise the windshield wipers
In preparation for snowfall, raise the windshield wipers up if the vehicle will be parked outdoors for a long period of time. This makes it easier to remove the snow from the windshield when next using the vehicle.
If you leave the wipers as they are, the rubber blades may freeze onto the windshield and be difficult to detach.
Never make abrupt vehicle movements
Always make the necessary preparations in advance when driving on snowbound roads, and never suddenly move off, swerve, stop, or make any other abrupt movements. Failure to observe this may cause the vehicle to be uncontrollable when it goes into a spin or slides, which may eventually result in a collision. Perform all operations slowly and carefully.
Leave a wider gap between you and the vehicle in front
The risk of skidding on a frozen road in winter is tenfold higher than on a dry road in summer; hence, maintaining the same distance exposes you to a much greater danger. You may encounter oncoming vehicles that move over into your lane or vehicles in front of you that go into a spin. For your safety, you need to maintain at least three (3) times more distance than usual between you and the car in front so that you can respond to these situations calmly.
Use your headlights even during the day
Headlights are normally used at night or when visibility is bad, but we also recommend turning them on even in the daytime when the weather is clear. In addition to providing you with clear visibility, your headlights can warn oncoming vehicles and pedestrians of your presence.
Put gasoline incrementally at a time
Snowy driving conditions can reduce your fuel economy drastically, and cause greater fuel consumption. When you are planning to drive a long distance, keep in mind to refuel your vehicle as frequently as possible.
Beware of diesel fuel gelling
Diesel fuel components are prone to freezing in cold regions. Gas stations in such areas sell diesel fuel with antifreeze additives, so we recommend refueling the tank locally if you intend to park the vehicle for a long period of time.
Take care in areas that are prone to freezing
The following areas easily freeze over. Special care is required when driving on them.
- In and around intersections
- Bridges and the surrounding roads
- Shadowy mountain roads
- In and around tunnel entrances/exits
Watch out for black ice!
At first glance, black ice seems like a wet road.
Black ice refers to a thin coat of transparent ice covering the road that is indistinguishable from the normal asphalt road. If you see a wet, glistening surface on the road ahead, assume that it is covered in black ice and slow down. Such surfaces are extremely dangerous; even studless snow tires are barely effective against them. Be cautious especially at night and in the early morning.
