What does the actual clear road width subsidiary sign mean?
The "actual clear road width" subsidiary sign is used to show the actual width of the road between physical obstacles, such as narrow bridges or underpasses. This sign is always placed under the "Narrower road" main sign and indicates the width in meters, for example "3.5 m". The width shown is rounded down to the nearest 0.1 meter, so that drivers know exactly how narrow the road is. The sign is especially important for larger vehicles such as trucks and buses, but also for regular cars driving on narrow roads. If the road is too narrow for vehicles with legal width, a different sign is used, namely "Width limit".
This subsidiary sign helps drivers assess whether they can pass safely through narrow areas. It provides important information that can prevent accidents or situations where vehicles get stuck.
