What is the speed limit mnemonic for urban roads and highways?
4 Answers
Urban roads and highways speed limit mnemonic mainly includes: Roads without centerlines: Urban roads have a speed limit of 30 km/h, while highways have a speed limit of 40 km/h. Roads with only one motor vehicle lane in the same direction: Urban roads have a speed limit of 50 km/h, while highways have a speed limit of 70 km/h. Highways: For 2-lane highways: The right lane allows speeds between 60-100 km/h with a minimum of 60 km/h, while the left lane has a minimum speed of 100 km/h. For 3-lane highways: The far right lane allows speeds between 60-90 km/h, the middle lane between 90-110 km/h, and the far left lane has a minimum speed of 110 km/h.
Back when I was learning to drive, my instructor taught me a rhyme for urban road speed limits: 'City 50, highway 70, expressway 120,' meaning generally not exceeding 50 km/h in the city, 70 on highways, and topping out at 120 on expressways. Having driven for over a decade, this rhyme has been quite helpful, especially in unfamiliar areas without road signs—it helps me estimate speed. In the city with lots of pedestrians and vehicles, driving at 50 allows good visibility of pedestrians, while 70 on highways keeps things smooth. Actual driving should adjust to road conditions, like slowing down further in rain when braking distances are longer. Always watch for roadside speed cameras—speeding tickets and fines are minor compared to safety. Don’t make the same mistake I did in my younger days, speeding on empty roads and learning the hard way.
When learning to drive, I memorized the "57 70" rule, which simply means 50 km/h in urban areas and 70 km/h on highways. The exam will test this, and the examiner may ask what the rule means. However, don’t rely solely on the rule when driving—road signs are more accurate, like the 30 km/h limit in school zones. Stay flexible. I often notice new drivers tend to exceed speed limits, so I recommend setting up a speed reminder app on your phone to build good habits. Controlling your speed not only saves fuel but also reduces the risk of rear-end collisions—easing off the gas before intersections keeps you safe and stress-free.
Remember the rule '50 in the city, 70 on highways, and 120 on expressways'—speed limits are 50 km/h on urban roads, 70 km/h on highways, and 120 km/h on expressways. The rhyme is easy to grasp, but apply it flexibly: reduce speed by 10 km/h at night or in fog to prevent skidding; buses are frequent in the city, so keep a safe distance. Safety first—speeding increases accident rates by 30%, so disciplined driving is the most reliable. Regularly check your car's dashboard, avoid exceeding speed limits, and drive steadily for long-term safety.
