When passing through an uncontrolled intersection without traffic signals or speed limit signs, the maximum driving speed shall not exceed 30 kilometers per hour. Below is detailed information about vehicle speed: 1. Overview: Vehicle speed refers to the distance a vehicle travels per unit time, abbreviated as speed, commonly measured in kilometers/hour or meters/second. Vehicle speed is one of the three key parameters describing traffic flow and holds significant importance in traffic flow theory research. 2. Others: Vehicle speed can also generally refer to motor vehicle speed. To accommodate different purposes, vehicle speeds are mainly categorized into spot speed, segment speed, and design speed. Spot speed refers to the instantaneous speed when a vehicle passes a specific point on the road. Design speed is the predetermined speed used to establish design indicators for various geometric elements of the road and ensure their coordination.

I think at intersections without traffic lights, it's best not to exceed 30 kilometers per hour. This is because pedestrians or vehicles might suddenly appear on the road, and at higher speeds, it's impossible to stop in time. When I drive, I always slow down to under 30 before reaching such intersections, stay alert, and look around more to avoid blind spots at corners. You need to go even slower on rainy days or at night, as braking distances increase on wet roads. Don't underestimate this speed limit; accidents often happen in just a one or two-second difference. Safety comes first, rules are there to save lives, so don't take risks even if you're in a hurry. Make it a habit to pass through smoothly, to avoid regrets later.

According to traffic regulations, the speed at uncontrolled intersections must be kept below 30 kilometers per hour. The core of this rule is to prevent collision accidents—intersections are high-risk areas with pedestrians and bicycles crossing unpredictably, and vehicles competing for right of way. Reducing speed increases reaction space and ensures safety. I recommend drivers strictly adhere to this, not just by observing the speed limit, but also by monitoring traffic dynamics and easing off the accelerator to slow down in advance. Violating this rule inevitably leads to fines and penalty points, but more importantly, it risks harming innocent people. With years of driving experience, I've witnessed too many accidents caused by speeding—lessons that should never be forgotten.

Once I didn’t slow down at an intersection and almost hit an electric scooter rider, which gave me a cold sweat. Since then, I’ve strictly followed the 30 km/h speed limit, passing through slowly every time. This speed allows for timely braking and better visibility. Especially near schools or commercial areas, where there are many children and chaotic traffic, driving too fast is just asking for trouble. Safe driving is no small matter—checking the rearview mirror while slowing down and yielding instead of rushing can prevent many conflicts. In short, 30 km/h is the bottom line; don’t risk your life to save a few seconds.

Attention new drivers: maintain a speed limit of 30km/h when crossing unlit intersections. When I first learned to drive, I was always nervous, and my instructor repeatedly emphasized: slowing down is key—reduce to a safe speed in advance and keep your foot on the brake, ready to stop at any moment. Intersections can be complex, with other vehicles suddenly changing lanes, and 30km/h allows you to handle situations steadily. Don’t just look straight ahead—scan left, right, and behind to avoid blind-spot accidents. Also, remember the right-of-way rule: if others have priority, don’t rush. Keep your speed under control, and there’s naturally nothing to fear. As you gain experience, you’ll find that driving slower actually leads to smoother and safer journeys.

Unsignalized intersections in the community are all high-risk zones where speed must be limited to within 30 kilometers per hour. This not only prevents accidents but also accommodates pedestrians and cyclists—after all, every household has elderly or children going out. The consequences of speeding and causing a collision can be severe. Factors like road width and traffic volume at the intersection must be considered; during peak hours, driving even slower is necessary, and 30km/h strikes the right balance between efficiency and risk. During my daily commute, I always remind myself: slowing down at intersections benefits everyone, and waiting an extra second won’t hurt. A culture of safety is built on these small details—harmony comes when everyone follows the rules.
