Low beam (dipped beam, passing beam, meeting beam) headlamps provide a distribution of light designed to provide forward and lateral illumination, with limits on light directed towards the eyes of other road users to control glare. This beam is intended for use whenever other vehicles are present ahead, whether oncoming or being overtaken.

The international [[ECE Regulations]] for [[#Tungsten-halogen light sources|filament headlamps]]<ref>{{cite web|url= https://www.unece.org/fileadmin/DAM/trans/main/wp29/wp29regs/2013/R112r3e.pdf |title=UN Regulation 112 }}&nbsp;{{small|(313&nbsp;KB)}}</ref> and for [[High-intensity discharge lamp|high-intensity discharge headlamps]]<ref>{{cite web|url= http://www.unece.org/fileadmin/DAM/trans/main/wp29/wp29regs/R098r3e.pdf |title=UN Regulation 98 }}&nbsp;{{small|(843&nbsp;KB)}}</ref> specify a beam with a sharp, asymmetric cutoff preventing significant amounts of light from being cast into the eyes of drivers of preceding or oncoming cars. Control of glare is less strict in the North American [[Society of Automotive Engineers|SAE]] beam standard contained in [[Federal Motor Vehicle Safety Standard 108|FMVSS / CMVSS 108]].<ref>{{cite web|url= http://a257.g.akamaitech.net/7/257/2422/12feb20041500/edocket.access.gpo.gov/cfr_2004/octqtr/pdf/49cfr571.108.pdf |title=FMVSS No. 108 }}&nbsp;{{small|(2.00&nbsp;MB)}}</ref>
