Snow, black ice and winter tyres: clearing, driving style and the chain rule

What the exam asks here: Most students think: the windscreen is what I look through, so that is enough.

The trap

Many learners think: It is enough to clear only the windscreen of snow before setting off.

The rule is: You clear windows, lights, mirrors, roof AND number plates; you are already liable to a fine for insufficient sight through the windscreen OR the front side windows

Challenge

Most students think: the windscreen is what I look through, so that is enough. The book names a longer list — and tests exactly whether you know that list, not just its obvious part.

The model

Before setting off you clear windows, lights, mirrors, roof AND number plates of snow or ice (Book p.192) — you are already liable to a fine for insufficient sight through the windscreen or the front side windows. If the road surface is slippery, you reduce speed, keep more distance, brake earlier and more gently, and steer more carefully and smoothly (Book p.192).

Core

Before you set off, you clear windows, lights, mirrors, roof and number plates of snow or ice; you are already liable to a fine if you have insufficient sight through the windscreen and the front side windows (Book p.192). If the road surface is slippery, you take four measures to avoid a skid: reduce your speed, keep more distance, brake earlier and more gently, steer more carefully and smoothly (Book p.192). The advised speed on a sign applies under favourable weather conditions; in snow, black ice and slippery conditions your speed must be considerably lower than that sign indicates (Book p.193). In snowfall, just as in fog, you may use your rear fog light when visibility is under 50 metres, and your front fog light when visibility is severely limited (under about 200 metres). Do not use full beam during snowfall: you get blinded by the reflection of the light on the snowflakes, and full beam is already banned during the day anyway (Book p.194). Winter tyres are not mandatory in the Netherlands, but below 7 degrees and on a snow-covered road surface they give more grip than ordinary tyres; you recognise them by a snowflake symbol and an M+S logo. A minimum tread depth of 4 mm is advised for winter tyres (Book p.195). In the Netherlands the use of metal snow chains is banned; plastic snow chains are allowed (Book p.196).

Why it matters

A roof full of snow that comes loose while driving is just as dangerous for the cars behind you as a snow-covered windscreen is for yourself. On a country road in Odoorn, far from a gritting lorry, an adjusted driving style is often the only thing standing between you and a skid.

Active recall

At a petrol station in Zuidlaren you quickly scrape your windscreen free of ice and get in. The roof, rear window and number plate are still covered in a layer of snow. May you drive off?

Teach back

Explain: which parts of the car do you clear of snow before setting off, and why must you not use full beam during snowfall?

Memory hook

Windows, lights, mirrors, roof, number plate — all cleared. Metal chains banned, plastic allowed. Winter tyres: advised, not mandatory.

What to look at: Cleared of snow before setting off: windows, mirrors, roof, number plates. On the road on a slippery surface: slower, more distance, braking earlier, steering more smoothly.

Signs and law

Test yourself

Early in the morning, somewhere in Odoorn, there is a thick layer of snow on your car. You quickly wipe the windscreen clear and want to drive off. Is that enough, or does more need to be cleared of snow?

About Snow, black ice and winter tyres: clearing, driving style and the chain rule: which statement is WRONG?

  1. Winter tyres are not mandatory in the Netherlands; they do give more grip below 7 degrees and on a snow-covered road surface.
  2. In the Netherlands the use of metal snow chains is banned; plastic snow chains ARE allowed.
  3. You clear windows, lights, mirrors, roof AND number plates; you are already liable to a fine for insufficient sight through the windscreen OR the front side windows.
  4. During snowfall you may simply use full beam at night for better sight.

Correct answer: During snowfall you may simply use full beam at night for better sight.

Do not use full beam during snowfall, you get blinded by the reflection of the light on the snowflakes; full beam is already banned during the day anyway

Why learners get this wrong: Winter tyres are mandatory in the Netherlands as soon as it snows or freezes.

Open this question

On the N18 near Groenlo it is snowing hard and it is dark. You see little of the road ahead and no one is coming towards you. What do you do with your lights?

  1. Full beam on, because in snow in the dark you see further that way
  2. Full beam on, because without oncoming traffic it bothers no one else
  3. No full beam: it reflects off the flakes and blinds you
Show the answer

Correct answer: No full beam: it reflects off the flakes and blinds you

False — you think more light gives more sight in snow. During snowfall you do not use full beam: the reflection on the snowflakes blinds you, so you actually see less

Why learners get this wrong: During snowfall you may simply use full beam at night for better sight.
