Question

DentroTest · Accepted Answer

According to the General Traffic Regulations, when driving through tunnels or underpasses with no intention of overtaking, drivers of vehicles whose maximum authorized mass (MAM) does not exceed 3,500 kg (such as mopeds, motorcycles or passenger cars) must keep a minimum front safety distance of at least 100 meters or a time gap of 4 seconds. The distance of 150 meters (or 6 seconds) is reserved exclusively for heavy vehicles with a MAM over 3,500 kg, while 200 meters is not a figure provided for in the general rule for this maneuver.
