On highways, when encountering sharp curves at a speed of 60 kilometers per hour (typically 60 mph), it is permissible to drive below the minimum speed limit during turns, but not below 40 km/h. If necessary, you must slow down. Additional extended information is as follows: Overview: Expressways, also known as highways, are roads specifically designed for high-speed vehicle travel. The definition of expressways varies across different countries, regions, eras, and academic fields. According to China's 'Highway Engineering Technical Standards', expressways are multi-lane roads exclusively for directional and lane-based vehicle travel, with full access control. The average annual daily traffic volume for expressways should ideally exceed 15,000 passenger cars, with a design speed ranging from 80 to 120 kilometers per hour. Others: Countries and regions worldwide have their own construction standards for expressways, without a unified model. There are differences in expressway systems between different countries and regions. Some nations include certain controlled-access, non-full-interchange arterial roads as part of their expressway network.

When driving on the highway, it's perfectly fine to slow down when encountering curves, and I often do so. From a safety perspective, speeding through curves can easily lead to loss of vehicle control, especially when making sudden turns at high speeds, which increases the risk of skidding. I make it a habit to pay attention to curve warning signs on the roadside in advance and start easing off the throttle to slow down as soon as I see them, ensuring a smooth turn. The key is to avoid slamming on the brakes, as hard braking at high speeds might trigger the anti-lock braking system (ABS), causing bumps or skidding instead. Combine steering with gentle braking to smoothly reduce speed. In wet or low-visibility conditions, slowing down is a lifesaving technique. Maintaining proper speed not only protects tire wear but also reduces the risk of rear-end collisions. Follow speed limit signs and practice predictive driving for a more relaxed journey.

As a frequent highway driver, I believe slowing down on curves is essential, based on vehicle dynamics principles. When taking a curve at high speed, centrifugal force pulls the car outward. If the speed is too high, tire grip decreases, increasing the risk of losing control. By slowing down appropriately, stable grip and steering control can be maintained. I recommend starting to gradually reduce throttle about 100 meters before entering the curve, maintaining a steady speed through the turn. Utilize the ABS system to assist in preventing brake lock-up. Also, note that slowing down in heavy traffic reduces the probability of collisions with vehicles ahead or behind. In short, slowing down is not cowardice but a key component of intelligent driving, helping to handle unexpected situations like road obstacles or bad weather. It ensures safety while prolonging the vehicle's lifespan.

When encountering curves on the highway, I always slow down. Because curves are more prone to accidents than straight roads, not slowing down may cause the wheels to skid or the vehicle to roll over. My approach: ease off the throttle as soon as I see the curve sign, don't wait until the turn to hit the brakes. Taking action in advance makes steering easier and avoids sudden braking that can cause shaking. Keep the speed within the limit, and even slower in rainy weather. For safety, slowing down is the norm, don't compete with others for speed.
