Rule 125
The speed limit is the absolute maximum and does not mean it is safe to drive at that speed irrespective of conditions. Unsafe speed increases the chances of causing a collision (or being unable to avoid one), as well as its severity. Inappropriate speeds are also intimidating, deterring people from walking, cycling or riding horses. Driving at speeds too fast for the road and traffic conditions is dangerous. You should always reduce your speed when the road layout or condition presents hazards, such as bends sharing the road with pedestrians, particularly children, older adults or disabled people, cyclists and horse riders, horse drawn vehicles and motorcyclists weather conditions make it safer to do so driving at night as it is more difficult to see other road users.
