The maxspeed:conditional=* tag is used on ways to define the maximum legal speed limit which depends on certain situations, such as the time of day, weather, or another particular condition, for a highway=*, railway=* or waterway=*. This tag is used in addition to maxspeed=*, which specifies the normal maximum speed limit when the condition does not apply.

By default, values are interpreted as kilometres per hour. If the speed limit should be specified in a different unit the unit can be added to the end of the value, separated by a space.

The conditional maximum speed limit employs conditional restrictions syntax.
