A freeway is a sign, not a kind of road
Section 1 of the Act defines a freeway as "a public road or a section of a public road which has been designated as a freeway by an appropriate road traffic sign". That is the whole definition. Not how many lanes it has, not whether it is fenced, not whether it has a barrier down the middle — the sign is what makes it one.
Two signs do it. R401 marks where a dual-carriageway freeway begins, and R402 where a single-carriageway freeway begins. Both mean the same thing for your purposes: from that sign onwards, the freeway rules are in force.
R402 is worth a second look, because a single-carriageway freeway — one road surface, traffic in both directions, and freeway rules — surprises most drivers. It is also why "it is a freeway so there is nothing coming the other way" is an assumption rather than a rule.

Who and what may not be on a freeway
Regulation 323(1) and (2). The vehicle list is closed; the exceptions to the people-and-animals rules are in subregulation (4).
| Prohibited | Detail |
|---|---|
| A vehicle drawn by an animal | Regulation 323(1)(a) |
| A pedal cycle | Regulation 323(1)(b) |
| A motorcycle with an engine of 50 cc or less, or one propelled by electrical power | Regulation 323(1)(c) |
| A motor tricycle or motor quadrucycle | Regulation 323(1)(d) |
| A mobility vehicle of 230 kg or less designed for a person with a physical defect or disability | Regulation 323(1)(e) |
| A tractor or a haulage tractor | Regulation 323(1)(f), as substituted in 2014. A tractor used in the construction or maintenance of the freeway itself is excepted |
| People on foot | Except inside an area a sign reserves for stopping or parking, or for a cause beyond their control. Traffic officers, rescue and salvage workers, freeway construction and maintenance staff, essential-service and civil-protection personnel are excepted |
| Animals | You may not leave or allow an animal on a freeway, or leave one where it may stray onto a freeway, except in or on a motor vehicle or in a signed stopping or parking area |
| Hand signals | You may not give a hand signal while driving on a freeway, except for a cause beyond your control |
The hand-signal prohibition is the one people have never heard of. It exists because putting an arm out of the window at freeway speeds is dangerous — use the indicators.
Keep left, pass right, and get out of the way
Regulation 296(1) already requires you to drive on the left side of the roadway. On a freeway that is lane discipline: the left lane is where you belong, and the lanes to the right are for passing.
Regulation 298(1) then does the passing itself — on the right, at a safe distance, and you do not move back left until you are safely clear of the vehicle you passed.
Regulation 323(5) adds a duty specific to freeways, and it is an obligation rather than etiquette. If you are driving in the right-hand lane, or the lane furthest to the right, and you become aware that another driver intends to overtake you, you must steer into a lane to the left — safely — and you may not accelerate until they have passed.
Regulation 323(6) says how the driver behind may tell you: a visible signal by flashing their headlights. That is the lawful use of a headlight flash on a freeway, and it does not entitle anyone to tailgate you while doing it.
Stopping, and the shoulder
Regulation 323(2)(c) prohibits stopping a vehicle on a freeway. Three exceptions: in compliance with a road traffic sign or a traffic officer's direction, inside an area a sign reserves for stopping or parking, or for any cause beyond your control.
A genuine breakdown or a puncture is a cause beyond your control, so pulling onto the shoulder for one is within the exception. Stopping to take a phone call, to swap drivers, to read a map or to let a passenger out is not.
When you are stationary on the roadway or the shoulder for any reason, regulation 214 requires you to display at least one emergency warning sign, placed no less than 45 metres behind the vehicle along the roadway, with the reflective side facing the traffic that will approach.
And the shoulder is not a lane. Regulation 298A prohibits driving on the shoulder of a public road; the narrow exception it allows — daylight, a road with one lane in each direction, while you are being overtaken, at 150 metres visibility — is not a freeway situation at all. Ambulances, fire and rescue vehicles, breakdown vehicles salvaging another vehicle, traffic officers, freeway maintenance and civil protection are separately excepted from the no-stopping rule by regulation 323(4)(c).
Can a learner drive on a freeway?
The honest answer is that the sources do not say. Regulation 99, which sets out learner's licence codes and what a learner's licence authorises, does not mention freeways. Regulation 323, which sets out the special provisions for freeways, does not mention learners. Neither does the Act.
So rather than invent a rule in either direction, here is what the sources do impose on a learner who is on one.
Regulation 99(2)(a) applies wherever a learner drives. Unless the licence relates to a motorcycle or to a vehicle with no seating accommodation for a passenger, the learner must be accompanied by, and under the direct personal supervision of, a person holding a full licence for that class of vehicle, seated next to them — or immediately behind them where they cannot be seated next to them. Nothing about a freeway suspends that, and nothing about a freeway adds to it.
Regulation 323(1) does settle part of it by the back door. A Code 1 learner on a motorcycle with an engine of 50 cc or less, on an electrically propelled machine, or on a motor tricycle may not be on a freeway at all — not because they are a learner, but because the vehicle is prohibited. A Code 1 learner on a larger motorcycle is not caught by that list.
One practical note that is ours and not the law's: a driving school or a supervising driver may have their own view about a learner on a freeway, and that view is worth having. It is a judgement about readiness, not a legal prohibition.
Merging: what the manual says and what the regulations say
The Department of Transport's own learner-driver manual states that when a driver on a freeway notices a vehicle wishing to merge from an on-ramp, that driver must allow the vehicle to merge in front of them.
Regulation 323 contains no merging provision, and no merging rule was found anywhere else in the regulations. So the manual's statement is guidance from the syllabus rather than a regulation you can be cited under, and it is worth knowing in that form because the manual is what the learner's test is built on.
What the regulations do impose falls on the driver coming up the on-ramp. Regulation 299(2) says a driver shall not enter a public road unless he or she can do so with safety to himself or herself and other traffic. The obligation to find the gap is yours; courtesy from the traffic already there is the manual's expectation, not your entitlement.
The mistake
Treating 120 as the speed for everyone on the road. It is the road's limit. A goods vehicle over 9 000 kg is still held to 80 and a bus to 100, because section 59(4) of the Act means the lower of an applicable road limit and class limit governs — the higher road limit never lifts the vehicle's own.
The other one is using the shoulder as an extra lane in heavy traffic. Driving on the shoulder is prohibited, and the exception in regulation 298A is written for a two-way road in daylight while you are being overtaken — the opposite situation.
Freeway rules sit in the rules section
They are scored with the rest of the rules of the road, separately from signs and vehicle controls. The free readiness test takes a couple of minutes, needs no account, and shows the three sections apart.
Take the free readiness testCommon questions
Can a learner driver drive on a freeway in South Africa?
The regulations are silent. Regulation 99 says nothing about freeways and regulation 323 says nothing about learners. What does apply is the supervision rule in regulation 99(2)(a) wherever the learner drives, and regulation 323(1), which keeps a motorcycle of 50 cc or less, an electrically propelled machine and a motor tricycle off a freeway whoever is riding it.
What is the speed limit on a South African freeway?
120 km/h under regulation 292(c), unless a sign shows a different figure for that stretch. Vehicle class limits still apply on top: a goods vehicle over 9 000 kg is held to 80 km/h and a bus to 100 km/h, because where two limits apply the lower governs.
Is there a minimum speed on a freeway?
Not in general. The regulations set no minimum speed for freeways. A minimum applies only where the minimum speed sign R101 is displayed, and then it is the figure on the sign.
Which vehicles are not allowed on a freeway?
Animal-drawn vehicles, pedal cycles, motorcycles with an engine of 50 cc or less or propelled by electrical power, motor tricycles and quadrucycles, mobility vehicles of 230 kg or less for a person with a disability, and tractors and haulage tractors — except a tractor being used to build or maintain the freeway itself.
Can I stop on the shoulder of a freeway?
Only in compliance with a sign or a traffic officer's direction, inside a signed stopping or parking area, or for a cause beyond your control. A breakdown or a puncture qualifies; taking a call or swapping drivers does not. Put out your emergency warning sign 45 metres behind the vehicle.
Do I have to move over for a car that wants to overtake?
On a freeway, yes, if you are in the right-hand lane or the lane furthest right. Regulation 323(5) requires you to steer into a lane to the left, safely, and not to accelerate until they have passed. The other driver may signal that intention by flashing their headlights.
May I use hand signals on a freeway?
No. Regulation 323(2)(d) prohibits giving a hand signal while driving on a freeway, except for a cause beyond your control — which in practice means your indicators have failed.
