Why are some highways limited to 100 km/h while others are limited to 120 km/h?
1 Answers
Highways have different speed limits of 100 km/h and 120 km/h because: Domestic highways are mostly paved with asphalt, and the friction coefficient between the road surface and tires varies. Different sections have different speed limits due to varying road conditions. Relevant information about speed limits is as follows: 1. Introduction to speed limits: Speed limits usually refer to the regulation of driving speed within a certain numerical range for a certain length of road. 2. Purpose of speed limits: The main purpose is to pre-warn drivers to reasonably control their speed in subsequent sections ahead, prevent speeding hazards, and ensure driving safety. Speed limits are an indispensable and most important part of road transportation safety.
