Is 30 mph considered fast?

[VonEleanor]

An average speed of 30 mph is considered slow. Here is the extended content: 1. On highways, the speed limit is generally 120 km/h (about 75 mph), while on national roads, it is typically 80 km/h (about 50 mph). Therefore, driving at an average speed of 30 km/h (about 19 mph) on national roads or highways is relatively slow. 2. Whether an average speed of 30 km/h is fast or slow depends on the road section. For example, if the speed limit on a particular road is 90 km/h (about 56 mph), then 30 km/h is slow. However, if the speed limit is 20 km/h (about 12 mph), then 30 km/h would be considered speeding. 3. Drivers should adjust their speed according to road requirements—neither too fast nor too slow. Driving too fast increases aerodynamic resistance, leading to higher fuel consumption. Additionally, excessive speed reduces reaction time in emergencies, posing traffic safety risks. 4. Driving too slowly on high-speed roads can also be hazardous, as it may lead to rear-end collisions or other accidents. Therefore, drivers should choose an appropriate speed to ensure road safety.
