Correct answer
B. 70 m.
Explanation
You are driving on the A4 motorway - you can tell from the advance direction sign with the motorway number and from the layout of the road. The maximum speed limit for a passenger car on a motorway is 140 km/h. The minimum following distance from the vehicle in front on a motorway is easy to calculate: half of the speed in km/h expressed in metres, so at 140 km/h at least 70 m - answer B.
The Road Traffic Act says that when driving on a motorway or an expressway, a driver must keep a minimum distance from the vehicle travelling in front in the same lane, in metres no less than half of the number that gives the speed in km/h; the rule does not apply while overtaking. This is a minimum requirement - in rain or in heavy traffic the distance should be greater.
