Tagging

Roads

Tags for roads
tag=value description MUTCD signage Vienna Convention signage Other signage
headlight=required Use of headlights is always required by law MUTCD R16-7.svg R16-7, MUTCD R16-8.svg R16-8, R16-10, S30-1(CA) 🇪🇸 R-413
🇫🇷 B29
SADC: TR133

headlight=allowed Use of headlights is allowed but not legally required (likely should not be specifically tagged, just useful to know the signs that end the headlight=required required section) R16-11, MUTCD R16-9.svg R16-9 🇪🇸 S-24

headlight=recommended Use of headlights is officially recommended but not required D-500 (Canada) 🇨🇳 警-40

headlight=prohibited Use of headlights is prohibited 🇨🇴 SR-35

The above tags should be used on roads after an official sign (such as the examples in the above table) requires, recommends, prohibits, etc. headlights. In the US, this means tagging headlight=required in between and (known and often mapped as a "Daytime Headlight Section").

Please note the headlight or headlamp is often not the same as the daytime running lights (DRL), see Headlamp on Wikipedia. Thus, for eample the requirement for DRL in European Union since 2011 is not resulting in headlight=required.

Countries

Data Consumers should take into account country-wide (or area-wide) laws when assuming values for untagged ways (`no` in the US, Spain, etc. and `yes` in Switzerland, Sweden, Russia, etc.).

Mappers and Data Providers should take into account the same country-wide (or area-wide) laws when assigning values. It would be extremely redundant to tag headlight=required on every road in a country where that is the default. In these cases, the tag should be removed. It may, however, be a good idea to tag the country itself one way or another so that Data Consumers have an easily accesible default. For example: countries where headlights are required at all times could be tagged with headlight=required, countries where headlights are required outside of cities or urban areas could be tagged with headlight:conditional=required @ rural, and countries which officially recommend but do not legally require headlights at all times could be tagged with headlight=recommended as the default but still may have headlight=required signed sections.
