How low it gets here
Of the 634 restrictions in Hertfordshire, 127 are under 2.5 m, 23 sit between 2.5 and 3.2 m — the band where a typical motorhome has to stop — 22 between 3.2 and 4.0 m, and 82 above 4.0 m. The median signed clearance is 2.40 m.
What the numbers leave out
380 of them state no height at all. That is not a clear road: somebody recorded a limit without a number. Treat those as obstacles of unknown height. Where nothing is signed, the general limit in United Kingdom applies — 5.03 m.
