- Height indication of an underpass.
Height indication of an underpass. The indicated clearance helps you assess the underpass; do not confuse this information with closure sign C19.
How to recognise the sign
Read the image, arrows and any text on sign L1; they distinguish this version within the information category.
Difference from C19 — Maximum height
L1: Height indication of an underpass. C19: Closed to vehicles higher than 3.1 metres. Read the separate application of C19 too; similar appearance does not mean identical meaning.

Practise this sign for your theory exam
Underpass height belongs to the Information category. In the CBR theory exam a traffic sign is almost never asked on its own: you are shown a situation and have to know what you may or must do in it. In the free sign trainer you practise the signs by category, with the explanation shown right after every answer.
