Speed: two principles without their own number (see h04 for the maxima)

What the exam asks here: This atom does not re-explain the full table of standard maxima (50/80/100/130, the trailer-90 rule, the minimum speeds) — that full, numeric treatment lives at h04_snelheid_afstand.

The trap

Many learners think: The rule 'you must be able to stop within the distance you can see to be clear' sets a fixed maximum speed in km/h, just like the other speed rules.

The rule is: This rule names no number at all. It establishes THAT you must be able to stop within what you can see and what is clear — a relative standard that varies per situation, not a fixed maximum

Challenge

This atom does not re-explain the full table of standard maxima (50/80/100/130, the trailer-90 rule, the minimum speeds) — that full, numeric treatment lives at h04_snelheid_afstand. Here the focus is on something that comes before any number: when a sign, or the situation itself, sets a limit that no numbered law article describes.

The model

You must always be able to stop within what you can see and what is clear — no number, a relative limit that shifts with fog, bends or darkness. A deviating sign outranks the standard rule — the number is on the sign, not in this article.

Core

The stop-within-sight rule is a relative standard: the driver must be able to bring the vehicle to a stop within the distance over which they can see the road and which is clear. In fog that distance is short, on a straight, clear road it is long — no number in the statutory text itself, yet a hard requirement. The 'sign beats rule' principle lays down the general rule that also applies to speed: a traffic sign (a speed sign) outranks the ordinary traffic rule, insofar as they are incompatible. As soon as a sign shows a different value than the standard maxima of this chapter, the sign governs. The standard maxima themselves — 50 km/h built-up area, 80/100/130 outside it, the 90 km/h with a light trailer, the minimum speeds of 50/60 km/h on motor(way)s — are deliberately not repeated in this atom; that full table lives at h04_snelheid_afstand.

Why it matters

Without these two principles the exam can seem contradictory: a sign lower than the standard maximum speed feels 'optional', and fog with no sign feels like 'no rule at all'. Both feelings are wrong: the sign always wins, and the sight-distance principle always applies, even without a sign.

Active recall

On a country road near Apeldoorn, dense fog, no sign at all. What governs how fast you may drive here?

Teach back

Explain: why does the stop-within-sight rule name no number, and what happens per the 'sign beats rule' principle when a sign shows a different speed than the standard maxima?

Memory hook

Stop within what you see, no number. The sign always wins. Maxima table: see h04_snelheid_afstand.

Signs and law

Test yourself

On a country road just outside Apeldoorn you are driving in dense fog. There is no sign showing a lower speed at all. May you then simply drive the standard maximum speed?

Show the answer

You must always be able to stop within what you can see and what is clear — no number, a relative limit that shifts with fog, bends or darkness. A deviating sign outranks the standard rule — the number is on the sign, not in this article.

Exam questions on this topic

One evening you drive outside the built-up area near Apeldoorn on a winding country road with no speed sign; the limit here is 80 km/h. After a sharp bend you can see only about 30 metres of the road. You must then drive so slowly that you can stop within those 30 metres.

  1. True
  2. False
Show the answer

Correct answer: True

False — you think only the 80 km/h limit counts. On top of the limit you must always be able to stop within the distance you can see and that is clear. If you can see only 30 metres of road, you drive much slower than 80.

Why learners get this wrong: The rule 'you must be able to stop within the distance you can see to be clear' sets a fixed maximum speed in km/h, just like the other speed rules.

Open this question

On an 80 km/h road outside the built-up area near Apeldoorn, a temporary sign at roadworks shows 50. Because of the barriers and a bend you can only see a short way ahead. How fast do you drive?

  1. At most 50 km/h, and slower if you cannot see far ahead
  2. Simply 50 km/h: whoever keeps to the number on the sign drives correctly
  3. At most 80 km/h, because the standard for this road outranks the sign
Show the answer

Correct answer: At most 50 km/h, and slower if you cannot see far ahead

False — you think the speed rule is only a fixed number. You must also always be able to stop within the distance you can see and that is clear; with little view you therefore drive slower than the sign. (VekaBest H1 begrippenkader (wettelijke basis, RVV art. 19/63) — THIN ATOM, geen VekaBest-hoofdstuk 7-herhaling; zie h04_snelheid_afstand voor het boekmateriaal p.117-126)

Why learners get this wrong: The rule 'you must be able to stop within the distance you can see to be clear' sets a fixed maximum speed in km/h, just like the other speed rules.

Open this question

You are driving outside a built-up area on a road where 80 km/h is the standard limit. Before a bend there is a 60 km/h sign. After the bend there is dense fog and you can see the road only about 30 m ahead. How fast do you drive there?

  1. So slowly that you can stop within the 30 m you can see
  2. 60 km/h, because that is what the sign here gives as the maximum
  3. 80 km/h, because a sign cannot lower the standard limit of 80 km/h
Show the answer

Correct answer: So slowly that you can stop within the 30 m you can see

False — a maximum is not a fixed driving speed. Alongside every maximum, this always applies: you must be able to stop within the distance you can see and that is clear. If you can see only 30 m, drive so slowly that you stop within those 30 m, even if that is far below 60 km/h.

Open this question

On a country road near Apeldoorn, dense fog, no sign at all. What governs how fast you may drive here?

  1. You must be able to stop within what you can see, even though no sign names a number
  2. Without a sign, no speed rule applies at all in the fog
Show the answer

Correct answer: You must be able to stop within what you can see, even though no sign names a number

The stop-within-sight rule always applies, with or without a sign, precisely without a fixed number.

Why learners get this wrong: The rule 'you must be able to stop within the distance you can see to be clear' sets a fixed maximum speed in km/h, just like the other speed rules.

Open this question

A lower speed sign can never override the standard maximum speed, because the standard rule is written directly into the law.

  1. False
  2. True
Show the answer

Correct answer: False

Traffic signs outrank traffic rules, insofar as incompatible. A speed sign that deviates from the standard maxima wins instead

Why learners get this wrong: A lower speed sign can never override the standard maximum speed, because the standard rule is written directly into the law.
