Road marking norms by country

The document each country's road markings come from, a link to the regulator, and the dimensions CapCad draws from it — read straight out of the drawing engine, so this page and the software always agree.

Norms

Published by the issuing body — we link to the source rather than host a copy, because these documents get revised.

SADC Road Traffic Signs Manual, Volume 1 — Chapter 7, Road Markings
SADC · 2012
Defines every marking and its legal effect: RM1 forbids overtaking, RM2 forbids overtaking and crossing, and the words centre line and barrier line are retired. Also the module system and the barrier sight distances of Table 7.4.
SADC Road Traffic Signs Manual, Volume 4 — Chapter 12, Road Markings
SADC · 2012
The dimension tables, including the legally prescribed minimum widths and the painted island geometry of Figure 12.1.
SADC Road Traffic Signs Manual, Volumes 1 and 3 — Regulatory and Warning Signs
SADC · 2012
Sign numbering: R1 stop, R2 yield, R201 speed limit with the value as a suffix, and the W202 to W211 curve family. South Africa uses the same numbers, having adopted these volumes in place of its own.
TRH 17, Geometric Design of Rural Roads
South Africa, Committee of State Road Authorities · 1988
Stopping, passing and decision sight distances. South African rather than regional, so apply it to other member states with care.
