A vehicle must not be driven at a speed exceeding that which will enable its driver to bring it to a halt within a distance the driver can see to be clear.
This section describes the rules for keeping pace in traffic and the speed limits that apply on different types of road and to different vehicles.
As a driver, you must always be aware of your speed and judge the appropriate speed for your vehicle, taking into account:
other users of the road,
current weather conditions,
all possible hazards, and
Driving conditions relate to the volume of traffic around you and the quality of the road.
Other users of the road include motor-cyclists, cyclists, pedestrians, school children, animals and all others you as a driver should anticipate will or may be on the road.
Possible hazards include anything you can see that can, and will, give rise to an emergency, such as oncoming traffic if you are turning onto a major road. They also include anything you cannot yet see and anything you can reasonably expect to happen, such as a pedestrian walking onto the road in front of you, a child running onto the road between parked cars, and or animals on the roadway. It includes your own physical and mental state while driving (for example whether you are stressed or tired) and the condition of your vehicle.
