What are the wrong practices for motor vehicles driving on highways?

[DelRicardo]

Motor vehicles driving on highways should avoid straddling or riding on the lane demarcation lines or driving on the shoulder. Below are precautions for highway driving: 1. Speed: (1) For novice drivers who feel unsure, it's recommended to maintain a speed between 80~100 km/h on highways, with 90 km/h being ideal. (2) When exiting the highway and entering the ramp, apply the brake twice: first, reduce speed to 60~70 km/h upon seeing the 500-meter exit sign; second, slow down to 40 km/h when entering the ramp. 2. Driving and lane changing: Generally, lane changes or merging are unnecessary. Overtake directly when passing others, and if encountering slower vehicles occupying the fast lane, change lanes to overtake from the right.
