Correct answer

  • B100 metros como mínimo.At least 100 metres.
Explanation

In tunnels or underpasses, when you do not intend to overtake, you must always keep a safe distance from the vehicle in front of at least 100 metres or a time gap of at least four seconds. For vehicles with a maximum authorised mass (MAM) over 3,500 kg, the safe distance is at least 150 metres or a gap of at least 6 seconds. Remember that overtaking is forbidden in tunnels unless there is more than one lane in your direction. The sign in the picture reminds us of the general safe distance we must keep.
