Can a smart car be driven on the highway?

[White]

smart car can be driven on the highway. The precautions for highway driving are: 1. The driver and front-seat passenger should fasten their seat belts, and the driver should not answer phone calls; 2. Avoid sudden steering wheel movements while driving at high speeds; 3. Do not change lanes arbitrarily while driving. When changing lanes or overtaking the vehicle ahead, the turn signal must be activated in advance; 4. Only adjacent lanes are allowed for overtaking, and the vehicle should immediately return to the driving lane after overtaking. Vehicles must not straddle or drive on the lane dividing line; 5. Do not reverse, drive in the opposite direction, make U-turns or turns by crossing the central divider, conduct test drives or drive training vehicles, or overtake or park on ramps; 6. Maintain a distance of more than 100 meters between vehicles. When the speed is below 100 kilometers per hour, the distance from the vehicle ahead in the same lane can be appropriately reduced, but the minimum distance should not be less than 50 meters.
