What does a sawtooth lane mean?

[StElena]

Sawtooth lanes, also known as 'tidal flow lanes,' are marked with dedicated indicator lights on the road. Driving in these lanes during non-operational hours is prohibited, and violations may result in a 3-point penalty and a fine ranging from 200 to 1,000 yuan. Below is some relevant information about tidal flow lanes: 1. Symbolic meaning of the name 'tidal flow lane': Just like the ebb and flow of tides, these lanes are specifically set up for peak traffic hours. When roads are heavily congested, tidal flow lanes can be activated. Above the entrance of these lanes, dedicated traffic signals are installed, which may vary by location. 2. Main purpose of tidal flow lanes: The primary goal of tidal flow lanes is to alleviate traffic pressure during peak hours. Eligible vehicles can use this 'dedicated lane' to avoid traffic jams. It's important to note that this lane is not a traditional 'dashed lane'—once entered, lane changes are not permitted, so drivers should plan their route in advance.
