The 'Four-On, Four-Off' traffic restriction is calculated based on calendar days, with each day starting after 0:00. There is no limit on the number of entries on the same day. The count is not reset every month, and restricted days should be determined based on previous travel records. It is recommended to use tools to check the restriction periods. Introduction to 'Four-On, Four-Off': 'Four-On, Four-Off' is a traffic measure implemented by the Guangzhou Municipal Public Security Bureau Traffic Police Detachment for non-Guangzhou registered small and medium-sized passenger vehicles. It stipulates that non-Guangzhou registered small and medium-sized passenger vehicles entering the central area of Guangzhou cannot drive continuously for more than 4 days (calendar days). After that, they must wait at least 4 days (calendar days) before entering again. Vehicles exempt from the 'Four-On, Four-Off' restriction during the validity period: Government vehicles include official vehicles for provincial and municipal governments stationed in Guangzhou. Business vehicles cover those frequently entering controlled areas for essential business needs of key enterprises. Cross-city commuter vehicles include those for individuals living outside Guangzhou but working in Guangzhou, who do not own a Guangzhou-registered small or medium-sized passenger vehicle and are not eligible for a Guangzhou small and medium-sized passenger vehicle quota. They can apply for a one-time transitional registration.

I've been driving for many years, and the 'drive four days, stop four days' rule doesn't actually start counting from midnight. It begins calculating from the moment you first enter the restricted zone. For example, if you drive in at 3 PM on Thursday, then your four driving days end at 3 PM on Sunday, followed by four days of stopping until you can enter again after 3 PM the next Thursday. This is very important because many people mistakenly think it starts at midnight on the calendar day, leading to fines for violations. I've experienced this myself—I thought it started at midnight on Monday, but when I entered on Monday, I got a warning. The rule is designed based on actual entry time for fairness and precision, avoiding confusion caused by date boundary conflicts. Remember, it's best to use a mobile app to record your entry time before driving out to avoid mistakes.

As an ordinary car owner, I once asked the traffic department this question. The timing start point for the 'drive four days, rest four days' rule is the exact moment your vehicle enters the restricted zone, not the fixed midnight time. This arrangement ensures relative fairness for everyone's entry and exit times; for example, entering at 7 AM means the no-driving period ends at 7 PM. I've seen friends mistakenly believe the midnight rule and drive half a day extra, resulting in hundreds of yuan in fines. The rule aims to manage traffic flow and prevent congestion, so it's advisable to record the exact entry time immediately or use a navigation app for automatic reminders. Though it involves more details, remembering that the start point is the actual entry time rather than the calendar day saves hassle.

I just started learning to drive recently and was curious whether the 'drive four, rest four' rule starts counting from midnight. Later, I found out it's not. The timer starts from the moment you drive into the restricted zone, for example, if you enter at 2 o'clock, you must stop driving at 2 o'clock. I looked it up online, and this design is to avoid errors caused by date confusion. Beginners are advised to use a timer tool to remind themselves of entry and exit times, reducing hassle and making driving more comfortable.

Paying attention to the 'Drive Four Days, Rest Four Days' rule while driving is crucial; it doesn't start from midnight. The count begins from the moment you enter the restricted zone. It's advisable to note your departure time or set reminders using a navigation app to avoid waiting until midnight and misunderstanding the four-day cycle. I once overlooked this and received a warning—the rules demand precision, and the related fines aren't cheap. For safety, maintaining a habit of timekeeping is best.

The 'four days on, four days off' timing does not follow the calendar day's midnight standard, but starts based on the exact time the vehicle enters the restricted zone. This ensures fair and continuous allocation. I also understand that the rule's original intention is to optimize traffic and prevent loopholes caused by day changes at midnight. For example, if a car enters on Wednesday morning, the parking time will also end four days later in the morning. An additional suggestion is to utilize smartphone functions for automatic tracking to simplify operations and drive with more peace of mind.
