Inside a tunnel with more than one lane for each direction of travel, is overtaking permitted?

Correct answer

Yes, when there are no signs prohibiting it.

In general, inside a tunnel with more than one lane for each direction of travel, overtaking other vehicles is permitted as long as there are no specific signs prohibiting it, both on roads within and outside built-up areas. It is important to bear in mind that, even though the signage does not expressly prohibit overtaking, you must carry out this manoeuvre with caution and responsibility. Tunnels tend to have more limited visibility and space than open roads, which means you must carefully assess whether it is safe to overtake another vehicle.
