Since the Emergency Highway Energy Conservation Act in 1974, which made the 55 mph national maximum speed limit on interstate highways in the US. The limits have been on the increase. The National Highway System Designation Act of 1995 gave states complete freedom to set interstate speed limits. As a result of such legislation, …show more content…
You might ask why cant there just be a limit to what cars can go when they are made. With the highest speed limit in America being 85 mph, shouldn't all cars in America just be governed to 85 mph? The simple answer is no. If you governed cars to only be able to do certain speeds there would be lots of problems. First and foremost these contraptions could probably be taken off the car and with modifications the cars could do over the governed limit. Also if you restricted speeds you would have to lower the power output of cars and when you are trying to go up a hill or there is a large headwind you wouldn't be able to get to the appropriate speed.without the power to accelerate quickly you wouldn't be able to merge onto a highway correctly because you wouldn't get up to the speed limit in that time. Another reason why you wouldn't be able to restrict power is because when a truck need to tow something you need more power generated to cope with the extra load ur towing. When you look at braking distances from the Highway code you see about 315 feet to come to full stop when traveling 70 mph. 240 feet to stop when traveling 60 mph. The distances above are based on a reaction time of 0.67 seconds, this assumes the driver is alert, concentrating and not impaired. Driving when tired, distracted or impaired significantly increases reaction times, meaning the distances would go up. These distances are what was to be thought of safe stopping distances in the 1990’s when they were
