Failure to comply with the speed limit regulations on the highway is an illegal act in itself, which will greatly increase the risk of accidents. For the safety of you and others, please be sure to abide by the speed limit. If you encounter special circumstances and need to adjust the speed (such as bad weather or emergencies), the following are legal and safe suggestions for response.： ### 1. **Strictly abide by the legal speed limit** -**Significance of speed limits**: Highway speed limits are set based on road design, traffic flow and safety assessment. Speeding will significantly shorten the braking distance and increase the severity of the accident. -**Consequences**: Speeding may result in fines, points deductions, and even serious traffic accidents. ### 2. **Safe driving recommendations under special circumstances** -**Bad weather**: Such as rain, fog, ice and snow, you should take the initiative to reduce the speed below the speed limit, maintain a longer distance than usual, and turn on the fog lights or hazard warning flashes. -**Congestion or accident**: In case of congestion or accident in front of you, you should slow down in advance, avoid emergency braking, and follow the principle of "slow-stop-slow". -**Vehicle failure**: Turn on the double flashing lights, drive slowly into the emergency lane, and place a warning sign 150 meters behind the car. ### 3. **Active defensive driving skills** -**Keep the distance from the car**: Keep the distance from the car for at least 3 seconds (double the distance on slippery roads). -**Predict risks**: Observe the brake lights of the vehicle in front, road obstacles, etc., and slow down in advance. -**Avoid distractions**: Eliminate behaviors such as mobile phones and tired driving, and the reaction time will be shorter when speeding. ### 4. **Emergency handling** -**Flat tire**: Hold the steering wheel tightly, click the brake to slow down, and do not rush to the direction. -**Risk of out of control**: If the speed is too fast and the vehicle drifts, loosen the throttle and lightly adjust the direction to restore control. ### Please remember： For every 10 kilometers per hour increase, the braking distance increases exponentially. The braking distance of 120km/h is far more than 100km/h (dry roads can reach more than 100 meters). The importance you attach to your own life is also the responsibility to other road users. If it is necessary to adjust the travel time, it is recommended to leave early or choose an alternative route instead of risking speeding. Arriving safely is more important than arriving quickly.
