Signs used for physical maxheight


This tag is new, and still not supported by rendering or routing software, and should therefore be used together with maxheight=*.

Possible tagging mistakes

Country Sign Explanation
Netherlands Nederlands verkeersbord L1.svg This sign denotes a regulatory limit, which is always less than the physical limit, so it must be tagged as maxheight=4.2 instead of maxheight:physical=4.2. Note the regulatory limit indicated by this sign only affects exceptional transports (the value is always ≥ 4 m). In the Netherlands, a proper value for maxheight:physical=* cannot be deduced from road signs, but may be obtained from other information sources.
