It depends:
A person hit by a car doing 30 mph (50 kmph) or under has a 80% chance of surviving 20% at 40 mph (62 kmph ish)
Automobiles are designed to be safest at normal road speed
The police have no sense of humour
My insurance bill is already too large and I have no points
Tires are rated for maximum speeds for a reason
Every time you double the speed you increase the stopping distance by more than four times. 50 mph gets stopped pretty quick. From 100 mph you end up in the ocean from Nevada.
People that die in crashes that excessive speed is a factor should be treated as suicide. (my opinion)
If you want to drive fast buy or build a race car like me. Great fun.
For safety.
Roads are built for safety and speed limits are determined by the conditions of the road on which they are posted.
Safety for both the crews and drivers in the pit.
It sets the speed at which Highway Safety Engineers determine can be driven safely on that stretch of roadway.
Before the 1940s there were no speed limits, as there was no need for them. The road system didn't support high speed travel to such an extent that a law restricting speed was a requirement. The speed limit was a twofold measure to limit fuel consumption and increase safety.
The Autobahn is Germany's superhighway system known for its high-speed limits and efficient design. It is a network of controlled-access highways without a general speed limit, though some sections do have advisory speed limits for safety.
Speed limits are based on safety, not entertainment, and many factors contribute to setting a speed limit. Residential areas, business areas and school areas all have reduced speeds because of the likelihood that a pedestrian could be hit or killed, and to allow for congestion. Freeways and interstates have higher limits because access is limited and usually moves in one direction only, making driving safer. Some people believe that governments lower speed limits to raise revenue and do not focus on safety.
In order to maintain the safety of drivers, the individual states can determine the speed limits depending on the quality of local roads.
Perhaps, the changing(increasing) number of population which most likely results to increase in the demand for transportation and therefore to the change it speed limits to regulate traffic and safety of commuters and drivers.
speed limits and operation restrictions.
Advantages of speed limits include improved road safety by reducing the risk of accidents and fatalities, better traffic flow and reduced congestion. Speed limits also help in reducing fuel consumption and emissions. Disadvantages include potential frustration for drivers, longer travel times, and difficulty in enforcement. Additionally, some argue that speed limits are set too low and can impede the flow of traffic.
Studies have shown that raising speed limits can lead to an increase in traffic fatalities. However, the relationship between speed limits and death rates is complex and influenced by various factors such as enforcement, driver behavior, and road conditions. It is important to consider the overall impact on road safety before making conclusions about the effects of raising speed limits on death rates.
