From early morning, vehicles began leaving Hanoi for southern provinces and cities on the first day of the National Day holiday. Although traffic density on the Phap Van - Cau Gie expressway increased, the flow of vehicles remained steady.

Through patrols and inspections, the Traffic Police Department noted that most drivers complied with regulations regarding safe distances from the vehicle ahead. Incidents of speeding, lane encroachment, or frequent lane changes decreased, and no vehicles were found using the emergency lane.

According to the Traffic Police Department, maintaining a safe distance when traffic is heavy allows drivers sufficient time to react if the vehicle ahead slows down or changes lanes. This prevents sudden braking and constant acceleration, resulting in a smoother traffic flow and reducing the risk of chain collisions that cause congestion.

To maintain order on the route, traffic police forces increased patrols, guiding drivers to stay in the correct lanes and maintain safe distances. They also inspected and penalized cases of drivers deliberately tailgating.

Specifically, on the morning of 29/8, Expressway Traffic Police Teams 3 and 4 processed 4 cases of failure to maintain a safe distance on the Phap Van - Cao Bo - Mai Son - National Highway 45 - Nghi Son axis. Since 26/8, the two units have processed 20 drivers for this violation.

Most violations were detected through artificial intelligence cameras and zoom cameras at the expressway monitoring center. The system helps authorities monitor the distance between vehicles during circulation, recording images and license plates.

After receiving images, the Traffic Police identify the location, vehicle, and driver, cross-referencing them with road signs and distance markers to build a case file. Violating vehicles may be stopped at toll booths or issued a cold fine notice if they have already exited the route.

These enforcement efforts were implemented as Hanoi's gateways faced significant pressure ahead of the 5-day holiday. From 16h30 on 28/8, Do Muoi street, heading towards the Phap Van - Cau Gie expressway, experienced congestion for over 2 km, with cars moving slowly in a queue.

At the same time, Ring Road 3 elevated section saw congestion extending over 4 km from Trung Hoa interchange towards the western and southern gateways of the capital. Other routes, such as Vo Chi Cong, Vinh Tuy bridge, and Nguyen Trai, also experienced heavy traffic until evening.

After the peak exodus of residents from the city on the afternoon of 28/8, pressure at the southern gateway gradually decreased. Traffic police continued to maintain a presence on the Phap Van - Cau Gie route during the holiday, focusing on violations such as not maintaining safe distances, incorrect lane usage, and using the emergency lane.

"The ultimate goal of inspection and penalties is not the number of tickets issued, but to deter, warn, and raise the voluntary awareness of traffic participants to comply with the law," a Traffic Police representative stated.
