What does a sawtooth lane mean?
2 Answers
Sawtooth lanes, also known as 'tidal flow lanes,' have been established in some cities. Roads with these lanes have special indicator lights, and driving is prohibited during non-operational hours. If mistakenly entered, drivers will be penalized with 3 demerit points and a fine ranging from 200 to 1000 yuan, which is quite severe. Additional information: 1. The name 'tidal flow lane' is symbolic, much like the ebb and flow of tides, as these lanes are specifically set up for peak traffic hours. During severe traffic congestion, tidal flow lanes can be activated. Special traffic signals are installed above the entrances to these lanes, and the types of signals vary from place to place. 2. The primary purpose of tidal flow lanes is to alleviate traffic pressure. During peak hours, vehicles that meet the requirements can use this 'dedicated lane' to avoid traffic jams. It's important to note that this lane is not like the traditional 'dashed-solid line lanes'; once entered, lane changes are not possible, so drivers should plan their routes in advance.
Those serrated lanes, actually referring to the rows of zigzag raised lines on the road, were something I frequently encountered during my long-haul driving days in my youth. They're usually installed near highway exits or sharp turns. When you accidentally drive over them, the wheels make a rattling noise and the steering wheel vibrates sharply, serving as a wake-up call against drowsiness or speeding. This design is quite effective, especially during fatigued night driving—the sudden vibration instantly snaps you back to alertness, preventing lane departure accidents. However, be mindful of tire conditions; frequent crossings accelerate wear. It's advisable to regularly check tread depth—don't cut corners on tire maintenance. Ultimately, serrated lanes are passive safety installations by transportation authorities, acting as driver-friendly reminders, but their effectiveness depends on familiarity with road conditions.
