In which situation is it mandatory to maintain a minimum safety distance of 100 meters from the vehicle ahead, if you do not intend to overtake?

Question

DentroTest · Accepted Answer

The correct answer is driving through a tunnel. General Traffic Regulations stipulate that, for safety reasons in enclosed spaces (tunnels and underpasses), passenger cars and vehicles up to 3,500 kg must leave at least 100 meters or a 4-second gap if they are not intending to overtake. For vehicles over 3,500 kg, this distance increases to 150 meters or 6 seconds. In the other options (level crossings or overpasses), the general rule of 'sufficient distance to avoid collision' applies, but not this fixed figure.
