Highway driving for beginners in South Africa

The highway is where new drivers most often feel out of their depth. Speed is higher, consequences of mistakes are larger, and other drivers often behave unpredictably. Here's how to approach it.

Your first time: plan it

Don't accidentally end up on the highway for the first time during peak hour. Plan your first highway drive:

• Weekday mid-morning (9:30 AM - 11:30 AM) on a dry day
• Someone experienced in the passenger seat
• A route you've researched: know your on-ramp and your exit

Merging onto the highway

The biggest fear for new drivers. The rule is simple: match the speed of highway traffic before you merge.

1. Accelerate on the on-ramp to approximately 120 km/h (or the traffic flow speed)
2. Use your mirror and signal to indicate
3. Find a gap in the left lane
4. Merge smoothly - don't slow down and wait for a gap; that's dangerous
5. Cancel your signal once in lane

What not to do:

• Don't stop at the end of the on-ramp (terrifying for the car behind you)
• Don't merge at 80 km/h into 120 km/h traffic
• Don't cut across multiple lanes immediately after merging

Following distance

At 120 km/h, a car covers 33 metres per second. The average reaction time is 1.5 seconds. That means before you even touch the brakes, you've travelled nearly 50 metres.

The legal minimum is the 2-second rule (as tested in the K53 and learner's exam). Pick a fixed point on the road ahead. When the car in front passes it, count "one-thousand-one, one-thousand-two." If you reach the same point before finishing the count, you're too close. At highway speed, many defensive driving courses recommend 3 seconds for a safer margin.

In rain or at night: use at least 4 seconds minimum.

Lane discipline

South African law requires you to keep left unless overtaking. In practice, many drivers sit in the fast lane. As a new driver:

• Use the left lane for cruising
• Move right only to overtake, then return to the left lane
• Don't follow the bad examples around you

What to watch for

• Taxis changing lanes without indicating. Give them extra space.
• Trucks that are slow on uphill sections. Plan your overtake well in advance.
• Debris on the road, especially after rain. Tyres, ladders, gravel.
• Animals on rural sections of the N1, N2, and R61. Particularly at dawn and dusk.
• Potholes on older sections of national roads. Hitting one at 120 km/h can damage a tyre catastrophically.

Overtaking

Only overtake when:

• You can see well ahead (no blind rise or curve)
• You have enough speed advantage to complete the overtake quickly
• The adjacent lane is clear
• You signal before moving

Don't sit alongside a truck. Either overtake fully or fall back.

Stopping

Only pull over in an emergency. If you must stop:

• Signal and move to the hard shoulder (emergency lane on the left)
• Stop as far left as possible
• Switch on hazard lights immediately
• If possible, get occupants out of the car and behind the barrier

The hard shoulder is for emergencies only. Don't use it to overtake stationary traffic (common in Gauteng, illegal everywhere).

Speed awareness

120 km/h feels comfortable within a few minutes. That's the danger. At 120 km/h, a serious accident can happen before your brain fully registers the threat. Drive at the speed that allows you to stop within the distance you can see clearly.
