Driving on ice – technique for safe grip

Driving on ice demands completely different habits than driving on bare roads. The friction can drop to a fraction of what you are used to, and braking distance, acceleration and steering are all affected. With the right technique – gentle throttle, long distance, soft braking pressure and calm steering movements – you keep the car under control even when the road is mirror-slick. This article covers what you need to know for the theory test and for driving safely in winter.

Why ice is so treacherous

On icy roads grip can fall dramatically. Where dry asphalt gives you good friction, ice can offer so little grip that the wheels spin at the slightest throttle and lock under light braking. The most dangerous part is that the change often comes suddenly: a bridge, a shaded bend or an intersection can be icy while the rest of the road is bare.

Low speed is the single most important measure. The lower your speed, the more time you have to react, and the smaller the consequences if you lose grip. Read more about how grip is created in the article on grip and friction .

Setting off and getting started on ice

Setting off is often where things go wrong. If the drive wheels spin, you lose both forward motion and steering. Here is how to get going safely:

1. Release the clutch gently and apply little throttle – feel the wheels take hold before you increase.
2. Consider starting in 2nd gear on a manual car, so the torque to the wheels is lower and spinning is reduced.
3. Avoid sudden throttle. A steady, soft pressure gives better grip than jerks.
4. If the car has traction control (TCS) or electronic stability control (ESC) , let the system work, but remember it cannot conjure grip that is not there.

Uphill the challenge is even greater. Keep a steady speed, avoid stopping mid-hill, and see the article on setting off uphill on slippery surfaces .

Braking technique and distance

On ice the braking distance can be many times longer than on bare road. That is why distance is your most important safety margin. The three-second rule of thumb applies on dry roads – on ice you should multiply it.

Brake softly and in good time. If the car has ABS, you can hold steady pressure without locking the wheels – but still expect a long distance. Without ABS you must be extra careful, because locked wheels lose steering ability. Refresh the basics in the article on speed and distance and the three-second rule in safe distance .

Steering and adjusting speed

Calm movements are the key. Sudden steering, hard braking and heavy throttle are all ways to break the grip. Think smooth:

• Look far ahead so you plan in good time and avoid abrupt manoeuvres.
• Finish braking before the bend, not inside it.
• Do one thing at a time: either brake, or steer – not both hard at once.
• Reduce speed well before intersections, bridges and downhill stretches.

If you do lose grip and the car starts to slide, ease off the throttle and brake, look where you want to go, and correct calmly with the wheel. This is exactly what you train for in skid training on a practice track , which is a mandatory part of the training. For more practical advice, see driving on slippery roads.

How to recognise black ice

Black ice is a thin, transparent layer of ice that is almost impossible to see because the asphalt shines through. It usually forms on bridges, in shade and when the temperature is around zero. Signs to watch for:

• The road looks shiny and wet, but the temperature is around or below zero.
• The tyre noise suddenly becomes quieter than normal.
• The steering feels light and unusually “loose”.

If you suspect black ice, reduce speed immediately and avoid anything abrupt. Be especially alert to the similar phenomenon that occurs on water – aquaplaning – because the response is the same: slow down and steer calmly.

Good technique comes from knowledge and practice. Test yourself with a free theory test , and keep practising in the Eteo app until you feel confident and ready for the theory test.
