smart can go on the highway. But it is not recommended to drive on highways. The main reason is: In the collision test between a Mercedes-Benz smart and a C-class car, when two vehicles with vastly different sizes and weights collided, the tremendous impact caused the rear of the Mercedes-Benz smart to lift up, followed by a 360-degree rotation. In such a collision test at 50 km/h, the safety of the occupants inside the car was clearly difficult to guarantee. The consequences of an accident on the highway would be unimaginable. Additional information: 1. Pedestrians, non-motor vehicles, tractors, agricultural transport vehicles, electric bicycles, wheeled special-purpose machinery vehicles, full-trailer tractors, and motor vehicles with a maximum design speed of less than 70 kilometers per hour are not allowed to enter highways. 2. Highways indicate the speed limits for lanes, with the maximum speed not exceeding 120 kilometers per hour and the minimum speed not less than 60 kilometers per hour. On highways, the maximum speed for small passenger cars must not exceed 120 kilometers per hour, other motor vehicles must not exceed 100 kilometers per hour, and motorcycles must not exceed 80 kilometers per hour.

As a frequent driver of urban compact cars myself, I can clearly tell you that Smart cars are fully capable of highway driving. Based on my experience, when driving a Smart on the highway, it's important to pay attention to speed control. Due to its lightweight body and high center of gravity, it's advisable to maintain a speed between 80 to 100 km/h to avoid instability caused by excessive speed. Regular maintenance checks on tire pressure and the braking system are also essential to ensure safety. If there's strong wind on the highway, the car body may sway a bit, so wearing a seatbelt is crucial. Additionally, urban-designed models might be noisier on highways, but they offer good fuel efficiency, making them suitable for short trips. Remember, safety first—avoid prolonged high-speed driving to prevent increased vehicle wear.

As a regular driver who often takes compact cars like the Smart on highways, I can confirm it's absolutely highway-legal. I've driven it multiple times in zones with 80-90km/h speed limits, finding it stable and fuel-efficient. However, the Smart's small engine displacement means slower acceleration – don't rush to overtake. In dense traffic, extra focus is needed to avoid sharp turns or tailgating large vehicles, as its stability can't match bigger cars. Regular maintenance should prioritize checking the chassis and suspension for looseness. While convenient for short highway trips, longer journeys may warrant more comfortable alternatives. Always monitor weather conditions, reducing speed during strong crosswinds.

From a safety perspective, driving a Smart on the highway is feasible, but rules must be followed. I have experienced driving a Smart on the highway several times, and keeping the speed below 100 km/h is relatively safe. Its compact structure is not very stable in high-speed airflow and is prone to slipping, so it is recommended to use it only on roads with lower speed limits. At the same time, ensure that the vehicle's lighting system is functioning properly and equipped with an anti-lock braking system. Regular checks of the tires and steering system can enhance safety. If driving at night or in bad weather, try to avoid the highway. Related vehicle maintenance is key to avoiding major accidents caused by neglecting minor component issues.

Within legal limits, the Smart car is allowed on highways. I understand that speed limits may vary by region, for example, maintaining a speed of 80 km/h is optimal when driving on expressways. The vehicle must comply with traffic regulations, and ensure that insurance and license plates are valid. Pay attention to road signs while driving to avoid entering high-speed zones and violating the law. Personally, the Smart car has good fuel economy on highways, but the noise level is relatively high, affecting comfort. Regular maintenance such as oil changes and filter replacements can extend its lifespan, which is beneficial for long-term highway use. Additionally, monitor traffic flow and avoid peak hours to improve efficiency.
