Speed, Following Distance, and Overtaking Rules
Speed limits
In settlements the general limit is 60 km/h; outside settlements 90 km/h; on motorways 110 km/h (higher where signed). Buses and vehicles towing trailers are restricted further, and category D drivers must remember that a bus carrying passengers is held to lower limits than a car. Local signs set specific limits, and a driver must always choose a speed that allows stopping within the visible distance.
Following distance
There is no fixed metre rule; the standard is the distance needed to stop if the vehicle ahead brakes suddenly. In poor visibility, rain, or ice, increase it. The two-second rule is a useful approximation in dry conditions, doubled in wet and tripled on ice.
Overtaking
Overtaking is prohibited at crossings, on bends with restricted visibility, on bridges, at junctions (except where signs permit), and where a sign or solid line forbids it. Before overtaking, confirm the lane ahead is clear, no one is overtaking you, and the vehicle ahead is not signalling a left turn. Overtaking a bus at a stop requires extra care for pedestrians.
Traps
Questions ask whether you may exceed the limit to overtake (no) and whether a slow vehicle must be overtaken on the right (only where lanes permit). A frequent trap is the driver who begins overtaking as the solid line starts - the manoeuvre must be completed before the line, not started on it.
Worked example
At 90 km/h you cover 25 m per second. A two-second gap is 50 m. In rain, double it to 100 m. If you cannot see 100 m ahead, reduce speed until you can stop within the visible distance.
