It is commonplace for people to drive over the posted speed limit. According to statistics posted by the transport accident commission, “The risk of involvement in a casualty doubles with each 5km/hr increase in free travelling speed above 60km/hr and a 5km/hr reduction in speed can lead to at least 15% decrease in crashes.”
Drivers who speed on highways and freeways with no repercussions can quickly develop bad driving habits. These habits may transfer to speeding in construction and playground zones. This is dangerous since there is a chance of construction workers and children abruptly crossing the road without warning.
The attitude from some drivers is that speeding does no harm. It is socially acceptable to speed as long as you do not get caught. Such driving practices can only worsen with time and eventually spreading the behaviour to other new and inexperienced drivers. Issuing speed violation tickets to such people do not change their attitude pass the next street. But, making them to always second guess themselves every time they see a SCB; will change their attitude, most especially when they get their first speed violation tickets from photo radar officer disguise behind the billboard.
Law enforcement departments have limited resources available to enforce speed limits and keep the roads safe. It is not the best use of taxpayer money to hire and train additional traffic enforcement officers when there are more cost-effective solutions that can be used. There is also a danger for the officer to get struck by a vehicle if the culprit is driving at an excessive speed and cannot stop in time.
