|Specifies a conditional maximum legal speed limit on a road, railway or waterway, which only applies under certain circumstances|

|Tools for this tag|
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.
maxspeed:conditional=120 @ (06:00-19:00)
|Speed limit of 120 km/h applies only from 6-19 h, otherwise applies 130 km/h. |
||Conditional speed limit applicable to a specific transportation mode with a weight condition.|
|maxspeed:conditional=40 @ (Mo-Fr 08:00-09:30,14:30-16:00; PH off; SH off)||Conditional speed limits during school times.|
maxspeed:conditional=60 @ wet
|Wet weather conditional speed limit|
maxspeed:conditional=60 @ snow
|Snowy weather conditional speed limit|
maxspeed:conditional=100 @ winter
|Different speed limit in winter. Commonly used in Finland where it is not the same dates every year, but the switching date is country-wide and decided yearly by a Finnish authority (information in finnish).|
|maxspeed:conditional=20 mph @ flashing||Lower speed limit when lights are flashing (used around some schools)|
maxspeed:conditional=25 mph @ children_present
|Lower speed limit when children are present (used around some schools)|
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.
