On some roadways in the USA, state or local agencies require the daytime use of headlights. These 24/7 requirements may be enforced through specific statutes/regulations or through the enforcement of mandatory use road signs.

Identifying roads with headlight use requirements

Only roads with regulatory (black and white) road signs requiring 24/7 headlight usage should be set with the Headlights required attribute. The Federal Highway Administration has guidance for how roads must be marked for headlight use requirements in order to be enforceable. Although some states require headlight use during inclement weather, the Waze app does not support alerts for these kinds of weather-only requirements at this time.

In addition to road signs, some jurisdictions may have public GIS data or other mapping resources that outline where headlight use requirements exist.
