And further
- We use capital letters for the S, N, R road numbers, even if this is not (yet) stated on the signs. (Capital letters are the new standard)
- When roads are double numbered (e.g. S106/S122 Erasmus Bridge or A4/A58), the second road number is added as an alternative street name with road sign. This is just not shown on the map. We simply add this in the Wegschild TTS.
- If the sign shows a place name followed by a road number in brackets - for example Amsterdam (A4) - do not add this road number to the visual and spoken directions. If the road number is stated without brackets, please indicate the road number.
