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

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.
