Freeways are designed so that traffic can flow with as little disruption as possible and is governed by a specific, comprehensive set of rules. On a freeway, you shouldn't come across things that hold up traffic flow, such as:

1. Intersections
2. Turning vehicles
3. Parked vehicles
4. Pedestrians
5. Animals
6. Cyclists.

Although the number of 'everyday' driving hazards is reduced on freeways, you still need to drive carefully as freeway traffic usually moves very quickly.

Signs that show entry or exit to freeways are blue with red around the edges. Freeway direction signs are typically blue with white text. Some signs on freeways may have elements of green, which indicate that the roads and guidance indicated are for non-freeway roads ahead.

Hand signals are not permitted to use hand signals on freeways except for in emergencies.

The following vehicles are not allowed on freeways:

1. Bicycles or pedal cycles
   
2. Motor cycles with an engine capacity of 50 cc or less
   
3. Electric motorcycles
   
4. Motor tricycles or quad bikes
   
5. Tractors (unless used for road maintenance)
   
6. Animal drawn vehicles
   
7. Vehicles with a mass of 230 kg or less (e.g. vehicles constructed for use by disabled people)

Pedestrians are not allowed on freeways unless they are in a demarcated area for stopping or parking or there is a cause beyond their control that keeps them there.

Animals or animal drawn vehicles are not allowed on freeways unless they are inside a vehicle or in a area specifically demarcated for stopping or parking

Maintenance workers, emergency crews, construction workers and officials in the course of duty are exempted from these restrictions.

When driving on a freeway:

1. Keep left, unless you are overtaking
   
2. Watch for exit signs
   
3. Get into the correct exit lane in plenty of time
   
4. Signal for at least three seconds before you change lanes
   
5. You must not stop your vehicle, except in an emergency
   
6. You must not make a U-turn
   
7. You must not stop to let down or pick up passengers
   
8. If you miss your exit, don't stop and reverse – instead, drive on to the next exit.

If the vehicle behind you indicates a desire to overtake by flashing his headlights or side indicators, signal and move to the left if it is safe to do so.

In general, you may not stop on freeways unless you are instructed to do so by a traffic officer, you are in an area demarcated for stopping or parking, or for a cause beyond your control, for instance when your car breaks down.

If you break down on a freeway:

1. Indicate and steer your vehicle as far off the road as possible – don't stop suddenly
   
2. Lift up the bonnet and boot and, if possible, hang something white on the driver's door handle or window – this will show you need help
   
3. Turn on your hazard lights or use a safety triangle to warn approaching traffic
   
4. At night, turn on the inside light
   
5. If you don't have a cell phone and it isn't safe to walk to a telephone, stay in your car and wait for help
   
6. Don't stand on the freeway
   
7. If you need help from other drivers, leave plenty of space for them to stop – remember, vehicles travel fast on a freeway and it will take a while for them to slow down.
