|Multiple consecutive short and low bumps spanning the entire width of the road.|
|Used on these elements|
|Tools for this tag|
Multiple consecutive short and low bumps (a few cm at most; smaller than traffic_calming=bump would be) spanning the entire width of the road. The bumps would be spaced from a few times their own dimension to a few meters apart. The rumble strip causes noise and vibration intended to alert a vehicle driver about something beyond the rumble strip, not to cause the driver to slow the vehicle to negotiate the feature itself.
Do not confuse with longitudinally placed rumble strips to alert drivers that they are leaving their lane, which are generally not mapped by OSM. (See rumble strips.)
How to map
Add a point over the way, in the exact position of the rumble strip and tag it with traffic_calming=rumble_strip. In longer stretches, add or select the way corresponding to the entire length of the rumble strip and add the tag traffic_calming=rumble_strip.
