Following distance is one of the most frequently tested topics in the South African learner's licence exam. The practical rule is simple; the exam questions test the specific numbers.
Following distance requirements
The National Road Traffic Act requires a minimum following distance that allows you to stop safely if the vehicle ahead stops suddenly. The practical standard used in driver training and tested in the learner's exam is the 2-second rule (the AA recommends 3 seconds for a safer margin):
- Watch the vehicle ahead pass a fixed point (a sign, a road marking)
- Count "one-thousand-and-one, one-thousand-and-two"
- Your vehicle should not reach that same point before you finish counting
| Speed | Approximate distance |
|---|---|
| 60 km/h | ~33 metres |
| 100 km/h | ~56 metres |
| 120 km/h | ~67 metres |
Heavy vehicles
Vehicles over a certain length or mass must maintain greater following distances. Articulated trucks (Code EC) are required to maintain at least 3× the normal following distance from another heavy vehicle ahead. On long highway stretches, traffic officers enforce convoy spacing.
Emergency vehicles
If an emergency vehicle - ambulance, fire truck, police vehicle - is responding with lights and siren active, do not follow dangerously close or obstruct it. The standard figure tested in the learner's exam is 150 metres as the minimum following distance. Do not overtake an emergency vehicle responding to a call unless directed by an officer.
Towing distances
When towing a broken-down vehicle with a rope or chain:
- Maximum rope/chain length: 3.5 metres
- If the rope exceeds 3.5 m: a white cloth or flag must be attached at the midpoint
- Maximum speed: 30 km/h
- The driver of the towed vehicle must be at the controls
The learner's exam angle
Following distance questions typically cover:
- The 2-second rule
- Distance behind emergency vehicles (150 metres)
- Maximum tow rope length (3.5 metres)
- Maximum speed when towing with a rope (30 km/h)
The 150-metre emergency vehicle distance and the 30 km/h rope-towing limit are high-frequency exam questions. Know both numbers exactly.

Frequently asked
- What is the minimum following distance in South Africa?
- The NRTA requires a safe following distance that allows you to stop in an emergency. The practical guide most commonly used is 2–3 seconds of travel time. At 120 km/h, 2 seconds is approximately 67 metres; the AA recommends 3 seconds as a safer standard.
- How far must you follow behind an emergency vehicle?
- 150 metres is the commonly cited figure for the learner's exam. The NRTA requires that you not obstruct or follow an emergency vehicle dangerously closely when it is responding with lights and sirens. The 150 m figure is the standard tested answer.
- Does following distance change in the rain or at night?
- Yes. The 2-second rule is a minimum for ideal conditions. In rain, fog, or at night, the recommendation is 3–4 seconds or more. The legal minimum doesn't change, but prudent driving requires more space.
- What is the maximum length of a tow rope?
- 3.5 metres. If the rope is longer than 3.5 metres, it must have a visible cloth or flag attached to its mid-point. Maximum speed when towing with a rope is 30 km/h.
