Road works — what overrides what

What the rule saysWhere it goes wrongWhat you do
Temporary markings on the road surfacePrevails over the other markings applied on the road surface there, in so far as they are incompatible. The old lines stay in place but no longer count.Still following the solid line because art. 76(1) forbids crossing it. Where temporary marking says otherwise, it wins — that is exactly why art. 63a exists.Follow the yellow or temporary lines and ignore the white ones where they contradict.
Sign versus general limitTraffic signs rank above traffic rules: the sign sets the limit, even where it shows a higher speed than the road's general limit — that is how 70 roads inside the built-up area exist. Only the special limits (moped, trailer and the like) are never lifted by a sign: there the lower of the two applies.Applying «of two speeds the lower applies» to the ordinary sign as well. That rule of art. 63b holds only for the special limits and the gantry; the general limit can be raised by a sign.Follow the sign, above the general limit too; only your own special limit (moped, trailer) remains the ceiling.
Sign versus electronic gantryWhere two speeds appear — one on a sign, one on a gantry — the lower of the two applies.Thinking the newest or the nearest wins. The law looks at neither order nor distance, only at the figure.Here too keep the lowest figure — sign and gantry rank equally.
Instruction from an authorised personSpoken instructions and gestures of authorised, recognisable officers and traffic controllers must be obeyed. The gestures themselves are in Annex II.Taking anyone in a yellow vest for an authorised person. The law requires authorised AND recognisable as such; a road worker waving is not a traffic controller.Follow the instruction as soon as the person is authorised AND recognisable as such.
Closed laneRed cross: the lane may not be used. The hard shoulder may be used only in emergencies — a queue at road works is not an emergency.Staying in the closed lane until the last moment. Driving under the cross is not “merging late”, it is using a lane that is prohibited.Leave the closed lane in good time — do not drive on to the last moment.
Why the signing wins hereArt. 62 requires obeying signs carrying an order or a ban; art. 63 lets them prevail over the traffic rules in so far as those are incompatible.Inverting the whole hierarchy: first checking what “normally” applies and treating the signs as an extra. At road works the signing is the norm and the ordinary rule the exception.At road works read the signing first and only then think of the ordinary rule.
