It is rare to come across only one hazard at a time when driving. Most of the time you will have to deal with several hazards at once.

This means you will need to stay aware of all the hazards, but give most attention to the hazard that is most likely to develop into a dangerous situation and require you to take urgent action.

For example, if there are children playing near the kerb. They may run out after a ball or after each other. Using the system of vehicle control, choose a course as far away from the children as possible (while still keeping on your side of the road), check the mirror, use the brakes and slow down.

Identifying the ‘main’ hazard

The following illustrations show scenes involving multiple hazards for the driver of the blue vehicle. Remember, the main hazard is the one that is most likely to require you to take urgent action.

In this one-lane street scenario, the main hazard is the cyclist pulling out behind a parked red vehicle and moving into the direct path of a heavy vehicle that is fast approaching.

Identify this hazard.

Hazard A is the main hazard. The cyclist is about to pull out around the parked car and move into the path of the blue vehicle.


In this diagonal parking on both sides of the street scenario, the main hazard is the black car that’s trying to reverse out of its park but visibility is limited due to parked vehicles alongside it. The car is about to move into the direct path of a heavy vehicle that is fast approaching.

Hazard B is the main hazard. This car is reversing out of a parking space and is about to enter the path of the blue vehicle.


In this T intersection scenario with traffic at different directions, the main hazard is the green car that’s trying to make a right turn into a driveway near the intersection. The car is signalling and is about to cross path of a heavy vehicle that is fast approaching.

Hazard D is the main hazard. This car is about to turn across the path of the blue vehicle.


In this one-lane street with a zebra crossing scenario, the main hazard is a very young person, distracted by an adult on the other side of the road, is about to cross the road but not using the zebra crossing which is located near. A heavy vehicle is fast approaching the road where the young person is.

Going down steep hills

In a modern truck before descending:

  • select a low gear – one gear lower than you would use to climb the hill
  • use auxiliary brakes to control speed, where appropriate (not on slippery surfaces)
  • lightly use your foot brake to keep to a safe speed, if necessary.
