Safe Speed: A Critical Discussion

“Safety First” – An Inviolable Principle:

The theory of safe speed, developed by Dr. John Smith in his book “Road Safety: A Comprehensive Guide,” emphasizes safe speed as crucial for road safety. Traffic laws are based on scientific research on speed, as high speeds increase accident risk.

“Speed Kills”:

According to the World Health Organization (WHO), approximately 90% of traffic accidents are speed-related. Excessive speed hinders a driver’s ability to react to unexpected situations, especially in poor weather or road conditions.

Common Speed-Related Scenarios for Passenger Cars:

Scenario 1: Driving on an expressway at 100 km/h, while the maximum speed limit is 120 km/h.

Solution: Maintain the legal speed limit of 120 km/h. Exceeding the speed limit increases the risk of accidents.

Scenario 2: Driving on a national highway at 90 km/h, while the maximum speed limit is 80 km/h.

Solution: Reduce speed to 80 km/h to comply with traffic laws.

Scenario 3: Driving in an urban area at 50 km/h, while the maximum speed limit is 40 km/h.

Solution: Reduce speed to 40 km/h and be vigilant for pedestrians, cyclists, and other vehicles.
