You drive into a short 150-metre tunnel and see no sign showing the tunnel length (L13). Is that correct?
- No, sign L13 belongs at every tunnel, regardless of length
- ✓ Yes, sign L13 only belongs at tunnels longer than 250 metres
- No, that is an error by the road authority that you should report
Correct answer: Yes, sign L13 only belongs at tunnels longer than 250 metres
Explanation
False
Why learners get this wrong
- Sign L13 is placed specifically at tunnels longer than 250 metres
- Wrong. For a 150-metre tunnel sign L13 is precisely not required — there is nothing to report
