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.

This tag combines complexity of maxspeed tagging with complexity of conditional tags, but sometimes it is needed to record real complexity. See more info at Conditional restrictions and Key:maxspeed pages.
