What does it mean when there are dashed lines on both sides of the dashed line on the highway?

It means lane changing is allowed. It is used to remind drivers to slow down when approaching curves or downhill sections. As long as there is no solid line between the dashed lines, lane changing is permitted, but it must be done safely. Meaning of double dashed lines: When double dashed lines are painted on a road section, it indicates that the direction of travel can be changed over time. A white or yellow dashed line at the center of the road means that, under the principle of ensuring safety, vehicles can cross the line when overtaking or turning left. The meaning of double dashed lines is the same as that of single dashed lines, with the double dashed lines adding a three-dimensional sense to the lane. Yellow dashed line: A yellow dashed line at the center of a two-way two-lane road is used to separate opposing traffic flows. It is generally set on the centerline of the lane but is not necessarily limited to the geometric centerline of the road. Under safe conditions, vehicles are allowed to cross the line or turn left.
I've always enjoyed driving on highways. The dashed lines on both sides are actually lane markings, which simply mean you can change lanes. You're free to switch to the adjacent lane while driving, but always ensure safety since high speeds increase the risk of reckless lane changes. I've seen many accidents caused by ignoring this simple rule. Remember to use your turn signal before changing lanes and check the rearview mirror to confirm no cars are approaching. Also, in rainy weather, the markings become slippery and harder to see, making it easier to lose control, so slow down and stay focused in bad weather. New drivers often feel nervous, but practice makes perfect. Road design aims to keep traffic flowing smoothly, but following the rules is fundamental. In short, don't overcomplicate it—it's there to give you more freedom while driving.
From a safety perspective, dashed lines on highways indicate that lane changes are permitted, and there's no special meaning to them being painted on both sides—it's the same standard. I always remind myself to leave enough space when changing lanes, especially in heavy traffic; reckless behavior not only endangers myself but also affects others. During night driving, poor lighting and weak reflective markings can lead to misjudging positions, so it's best to use high beams to improve visibility. Additionally, checking blind spots and mirrors is a long-standing habit—never slack off. Road design prioritizes efficient traffic flow, but the key lies in drivers' self-discipline. I've also noticed variations in markings across countries, but the principle of dashed lines allowing lane changes is universal. Safety is no trivial matter—cultivate good habits.
Driving on the highway for a long time without changes in the dashed lines indicates that you can change lanes freely, as the dashed lines on both sides are the same. It means don't hesitate, but be responsible: accelerate smoothly without sudden braking, maintain a safe distance, and observe the traffic ahead and behind. In rainy or snowy conditions, the markings may become slippery, requiring even more cautious driving. The simplicity of road design aims to reduce confusion, which I find to be a convenience.
