This forms part of Map Editing Best Practices for Malaysia and Brunei. Editors are encouraged to follow these guidelines.

This policy is not intended as a guide to whether or not a segment should be locked. That should always be an informed decision made by an editor based on circumstances such as whether a road is "complete". This policy is a guide for the MAXIMUM locking level to be used for the convenience of the community, plus some notes about when not to lock:

  • You should not normally be locking segments unless they are complete:
    • Junction geometry adjusted for proper navigation instructions
    • Turn restrictions set correctly
    • Road type set correctly
    • Correctly named roads
  • You should not lock segments unless you are regularly visiting the forums to deal with unlock requests
  • If you lock segments, your name will be recorded on them and you will generally be considered responsible for their state

Any editor found mass-editing lock levels simply because this policy suggests a maximum lock level is likely to face reduction of editor rank and/or removal of AM/CM rights.

Road Types


Freeways should be locked to L5, including their associated ramps & junctions. They are primary routes that should all be correct by now and need to be protected to keep major routing working. Editing will normally only be done by level 5 editors or Malaysia Country Administrator

Major Highways

Major highways should be locked to level 5. They are also primary routes that should all be correct by now and need to be protected to keep major routing working. Editing will normally only be done by level 5 editors or Malaysia Country Administrator.

Minor Highways

Minor Highways should be locked at minimum level 4. Complex junctions or particularly important sections may be locked at level 4 by a local, active AM/CM if considered strictly necessary.

Primary Streets

Primary streets should be locked at minimum level 3.


Railroads should be locked at L5 to prevent accidental deletion.

Other Situations

Roads Not Matching Aerials

With the change to Google aerial imagery (which seems to be much older for some parts of Malaysia), there will probably be more situations where the current road layout doesn't match the images. It is advisable that these are locked at L5, to prevent well-meaning editors "correcting" them.

"Unexpected" Situations

These are odd situations that occur sometimes. For example: a no-right-turn where you wouldn't expect one; a short one-way segment at the end of a two-way road; a deliberate no-name segment joining double-mini roundabouts. If you think that a feature is likely to be reverted by someone who doesn't know what was intended, it is acceptable to lock it.


If an area is subject to repeated bad edits, it may be locked up. This should only be done after discussion with the community and the approval of the Malaysia Country Administrator (who may want to take further action).

Toll Segments

These should be locked to minimum L4 or L5 to prevent interference. This includes segments that is connected to Toll Segments without the Toll Road enabled.

Level 6 Locks

So far we have not identified any occasions where we really need to use L6 locks. We don't have so many L5 editors that we can't all keep track of what's going on, so we hope not to need it. But, if you have a situation that you feel needs a L6 lock, please post on the forum for discussion.


Landmarks that are important, or take a lot of effort to draw, should be locked. For example, sea, lakes and rivers, and gas stations.
