What does the zigzag line on the highway represent?

[LaErin]

The zigzag line on the highway represents longitudinal deceleration markings. Here are some precautions for driving on the highway: 1. Both the driver and front-seat passenger should fasten their seat belts, and the driver should not answer phone calls; 2. Avoid making sharp turns with the steering wheel 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 return to the driving lane immediately after overtaking. Vehicles must not ride or press on the lane dividing line; 5. Do not reverse, drive in the opposite direction, cross the central divider to make a U-turn or turn, do not test drive or operate a training vehicle, and do not overtake or park on the ramp; 6. Maintain a following distance of more than 100 meters. When the speed is below 100 kilometers per hour, the distance from the vehicle ahead in the same lane can be appropriately shortened, but the minimum distance should not be less than 50 meters.
