Author : Özlem Kahraman
In Turkey , to avoid the traffic accidents occurred due to excessive speed , to minimize the damage of exhaust emissions to nature and to prevent increased fuel consumption due to high speed , Highway Speed Corridor Application is in force .
According to the application , the minimum arrival time is determined by measuring the distance between the entrance and exit toll booths on the highways . If the drivers enter the highways from the toll booths and pass the exit before the specified time , it is considered that they have exceeded the maximum speed limit and a traffic ticket is applied . Speed limit set for highways ; 120 km / h for cars and 90 km / h for trucks . The speed limit penalties determined in the regulation are 235 TL if the speed limit is exceeded between 10 % and 30 %, and 488 TL if more than 30 % is exceeded .
Accordingly , for the 450 km long Istanbul-Ankara TEM highway , a ) Determine the minimum arrival times for cars and trucks in accordance with the speed limit . b ) Determine whether a truck driver who completes his journey in 4 hours will pay a traffic ticket , and if so , how much he will pay . c ) Determine whether a car driver who completes his journey in 3 hours and 15 minutes will pay a traffic ticket , and if so , how much he will pay .
